An international laboratory report says “arsenic: 3.4 µg/L, ISO 17294-2:2023,” but a translated PDF shows 3.4 mg/L. The chemical name survives, yet the reported concentration becomes one thousand times larger. Translating ICP-MS water-test reports accurately requires exact chemical identities, units, sample preparation, reporting limits and qualifiers. It also requires restraint: a measurement of an element does not by itself prove safety, contamination severity or compliance with a particular country’s drinking-water regulations.
This guide answers searches for ISO 17294-2:2023 translation, water-quality ICP-MS lab report translation, trace metal results in µg/L and mg/L, arsenic and lead analysis, uranium isotope data, limits of detection and quantification, total versus dissolved elements, laboratory blanks, sample dilution, measurement uncertainty and environmental certificate translation. Each section solves one local interpretation problem so a translator, laboratory customer, purchasing officer or educator can recover the intended scientific meaning.
The public ISO catalogue identifies ISO 17294-2:2023 as the third edition, published in October 2023 and corrected in February 2024. It addresses determination of many selected elements, including uranium isotopes, in water and certain digested matrices by inductively coupled plasma mass spectrometry. This independently written educational guide uses the public scope and general metrological principles; it does not reproduce licensed methods or pretend to replace a laboratory’s approved analytical procedure.
Read the measurement as an evidence system
The standard, quantity and scientific language
ICP-MS means a method, not a compliance verdict
Inductively coupled plasma mass spectrometry creates measurable signals associated with ionized elements and mass-to-charge behavior. The result depends on which elements were selected, how the water was prepared and how the laboratory validated its measurement. A machine name alone says nothing about whether drinking water is legally suitable.
Translation failure: A translated report says “ICP-MS approved water” where the source only names a method. First ask what physical quantity this term denotes. A chemical name, a concentration, a limit and a quality-control status all occupy different roles in an analytical record. English fluency can hide a category mistake, especially after a table has been extracted from PDF into plain text. A good translation makes the role visible before attempting to make it sound elegant.
Practical repair: Restore the analytical method and separate any later regulatory judgment, which needs its own criterion, context and authorized reviewer. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
The edition and the corrected version
The ISO 17294-2:2023 designation identifies the published method edition. The public catalogue also notes a February 2024 correction. A corrected version is not evidence that an old test used a brand-new edition, and a test date is not the same as a standards publication date.
Translation failure: A 2016 laboratory reference is silently rewritten as 2023 to make a brochure look current. Check the upstream record that gives this field meaning. A laboratory number is attached to an analyte, sample, method, preparation state and reporting convention. When those connections are lost, a plausible phrase can become scientifically false. Reconstruct the connections before choosing a target-language equivalent, then keep them in the final page.
Practical repair: Keep the historical citation, mark conflicts for clarification and never fabricate a laboratory procedure by editorial updating. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Analyte list versus the scope of the standard
The method can address many elements, but the published scope is not a statement that a particular laboratory measured every listed element in every sample. A report may contain only a selected panel or a limited request. The tested analyte list is normally found in the report’s own results table.
Translation failure: The summary claims mercury was not detected when the certificate does not include a mercury test. An abbreviated source often tempts editors to supply the sentence they think the author intended. That is where evidence can be fabricated. If the source is ambiguous, retain the ambiguity clearly or request clarification; do not fill missing data with a familiar textbook value, a default threshold or a convenient assumption.
Practical repair: Write “not reported” or leave the matter unasserted, rather than converting an absent measurement into a non-detect. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Chemical symbols preserve identity
As denotes arsenic, Pb lead, Cd cadmium, Hg mercury and U uranium. Exact capitalization is important: the symbol As is not the ordinary English conjunction as. A translated name should be linked to its invariant chemical symbol and the correct result row.
Translation failure: A layout program changes As to AS and an automatic glossary interprets it as a company abbreviation. Think about the next reader, not only the original translator. The value may travel into a procurement spreadsheet, environmental disclosure, government query or internal monitoring chart. A short qualification removed at translation time can become an apparent fact downstream. Keep distinctions explicit enough that an excerpt remains defensible.
Practical repair: Verify each symbol against the source row, retain scientific case and add the local-language element name only as clarification. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Units µg/L, mg/L and ng/L
Trace-element concentrations in water commonly use mass-per-volume units. One milligram is one thousand micrograms; one microgram is one thousand nanograms. The micro sign may render as µ or a plain-language equivalent such as ug, but converting it to m changes the magnitude.
Translation failure: 3.4 µg/L is reproduced as 3.4 mg/L although the value was not recalculated. Compare numerical data in the rendered PDF and the editable file. The wrong symbol, header or decimal separator can change meaning without producing a spelling error. For technical reports, visual proofing is part of semantic proofing: the layout tells readers which value belongs to which element, location and unit.
Practical repair: Retain the laboratory’s certified original unit and present any converted value in a separate, explicitly derived field. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Units, limits and preparation of water
The meaning of a litre
The denominator L refers to volume of the water sample, not to a kilogram of soil or a mass fraction of a dried solid. The same numerical value can describe a different physical quantity when a denominator is changed. A mixed report may include digested sludge and water, making that distinction essential.
Translation failure: A table of water concentrations is relabeled mg/kg after an unrelated soil-report template is applied. Separate the source evidence from any explanation added for teaching. It is legitimate to explain unfamiliar notation in a translator’s note, but not to rewrite the laboratory’s result as if the explanation were measured. Label the original figure and any calculated, inferred or externally sourced interpretation as different kinds of statements.
Practical repair: Read each sample matrix and denominator together; never change units to match a website’s preferred display style. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Detection and quantification are different boundaries
A detection limit concerns recognizing an analyte signal against background under particular conditions. A limit of quantification, LOQ, concerns a concentration that can be reported quantitatively with an acceptable performance basis. Neither limit is a universal chemical constant or a synonym for zero.
Translation failure: The phrase “below LOQ” becomes “none present,” creating a claim the instrument did not establish. A translation checklist should look for an authority boundary. Laboratories measure, regulators apply rules, clients define purchasing criteria and translators preserve meaning. Those responsibilities may meet in the same document, but a target-language phrase should not transfer one actor’s power to another. This is particularly important when a reader is looking for a simple pass or fail.
Practical repair: Preserve the limit, the qualifier and its unit; explain in ordinary language that concentration was not quantified above the stated reporting boundary. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Inequality signs are part of the numerical result
A report may use <0.2 µg/L to represent a bound rather than an exact concentration. Removing the less-than sign converts a qualified statement into an apparently quantified result. The legend may distinguish ND, NQ and other codes, and those meanings must come from the issuer.
Translation failure: A copy-and-paste operation drops the sign, leaving a clean but false 0.2 µg/L. Read the report as a chain of decisions. The sample is collected, prepared, measured, qualified and reported; only afterward may someone compare it with a criterion. If a translation jumps directly from an isolated figure to a product or health conclusion, inspect which evidentiary steps were skipped and restore the missing scope.
Practical repair: Compare the original laboratory image against the exported table and protect less-than signs, flags and footnote references as atomic data. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Matrix dependence and complex samples
A water matrix contains the other substances surrounding the target element: salts, organic matter, suspended material and relevant preparation reagents. Interferences and dilution needs can change the reporting performance. The public ISO summary expressly notes that working ranges vary with matrix conditions.
Translation failure: A low LOQ obtained for clean drinking water is presented as guaranteed for concentrated industrial wastewater. First ask what physical quantity this term denotes. A chemical name, a concentration, a limit and a quality-control status all occupy different roles in an analytical record. English fluency can hide a category mistake, especially after a table has been extracted from PDF into plain text. A good translation makes the role visible before attempting to make it sound elegant.
Practical repair: Retain the actual matrix, preparation method and laboratory-specific reporting limit; do not import idealized performance values into another sample. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Filtered and unfiltered portions
A dissolved-fraction result and a whole-sample result need not represent the same material. Filtering can separate particles, while other treatments may be used for defined total or recoverable measurements. These are operational descriptions attached to laboratory procedures, not interchangeable plain-language labels.
Translation failure: “Filtered sample, dissolved lead” becomes “total lead in all water and sediment.” Check the upstream record that gives this field meaning. A laboratory number is attached to an analyte, sample, method, preparation state and reporting convention. When those connections are lost, a plausible phrase can become scientifically false. Reconstruct the connections before choosing a target-language equivalent, then keep them in the final page.
Practical repair: Keep the source fraction, filtration note and test-method references; an additional total measurement cannot be generated through translation. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Quality-control evidence and analytical confidence
Digestion and extraction scope
Digestion can prepare sample constituents for measurement by transferring relevant material into a form the instrument can analyze. What is recovered depends on the selected process and analytical validation. A translation should not claim that every possible chemical form was dissolved merely because an acid digestion was performed.
Translation failure: The source names a digestion method; the translation promises “complete extraction of all metals.” An abbreviated source often tempts editors to supply the sentence they think the author intended. That is where evidence can be fabricated. If the source is ambiguous, retain the ambiguity clearly or request clarification; do not fill missing data with a familiar textbook value, a default threshold or a convenient assumption.
Practical repair: State what procedure was recorded and preserve the issuer’s qualifications instead of adding an unverified recovery guarantee. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Spectral interference versus contamination
An interference is an analytical complication that influences signal interpretation. Contamination refers to unintended material entering a sample or procedure. These are different problems even though both may affect confidence in a trace-level result. The vocabulary should reflect the particular QA finding.
Translation failure: “Interference investigated” is translated as “water contaminated during testing.” Think about the next reader, not only the original translator. The value may travel into a procurement spreadsheet, environmental disclosure, government query or internal monitoring chart. A short qualification removed at translation time can become an apparent fact downstream. Keep distinctions explicit enough that an excerpt remains defensible.
Practical repair: Keep interference, blank, carryover and contamination as distinct terms and identify which one the laboratory actually reported. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Method blanks and reagent blanks
At very low analyte concentrations, laboratory containers, reagents and processing steps can contribute measurable background. Blank samples help identify those possible contributions. A blank value is not an independent environmental monitoring station and cannot be inserted into the sample results as if it described a river.
Translation failure: “Blank 0.1 µg/L” is incorrectly presented as a tap-water concentration. Compare numerical data in the rendered PDF and the editable file. The wrong symbol, header or decimal separator can change meaning without producing a spelling error. For technical reports, visual proofing is part of semantic proofing: the layout tells readers which value belongs to which element, location and unit.
Practical repair: Label the blank’s exact control role and leave data treatment to the laboratory’s documented quality procedure. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Calibration and ongoing verification
Calibration establishes a relationship between known references and instrumental response. Verification checks that relevant performance continues to meet specified requirements. Neither process certifies that every environmental sample is safe. A report may also have controls applied at defined intervals throughout a run.
Translation failure: A verification pass is translated as a drinking-water safety approval. Separate the source evidence from any explanation added for teaching. It is legitimate to explain unfamiliar notation in a translator’s note, but not to rewrite the laboratory’s result as if the explanation were measured. Label the original figure and any calculated, inferred or externally sourced interpretation as different kinds of statements.
Practical repair: Preserve control names and outcomes, separating analytical performance evidence from a decision about a particular sample. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Internal standards are not sample ingredients
An internal standard is introduced for analytical control and correction in a validated procedure. Its measured behavior can help evaluate variation or interference. It is not evidence that a customer deliberately added that chemical to the sampled water, and its recovery is not the water’s contamination percentage.
Translation failure: “Internal-standard recovery 95%” becomes “the sample contains 95% metal.” A translation checklist should look for an authority boundary. Laboratories measure, regulators apply rules, clients define purchasing criteria and translators preserve meaning. Those responsibilities may meet in the same document, but a target-language phrase should not transfer one actor’s power to another. This is particularly important when a reader is looking for a simple pass or fail.
Practical repair: Translate the label as a laboratory control and keep percentages apart from mass-per-volume results. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Isotopes, species and interpretation boundaries
Spike recovery and fortified samples
Laboratories may introduce a known analyte quantity into a control or sample to evaluate analytical recovery. The reported percentage is a performance comparison based on that addition, not the environmental element concentration. It may have its own acceptance criteria and matrix-specific interpretation.
Translation failure: “Spike recovery 96%” is shown on a public pollution chart as a 96% contaminant level. Read the report as a chain of decisions. The sample is collected, prepared, measured, qualified and reported; only afterward may someone compare it with a criterion. If a translation jumps directly from an isolated figure to a product or health conclusion, inspect which evidentiary steps were skipped and restore the missing scope.
Practical repair: Retain the fortified-sample label and ask the laboratory to interpret any failed control instead of inventing a source-sample conclusion. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Dilution factors and final reported values
A laboratory may dilute a high-concentration or difficult sample before measuring it. Instrument readings, dilution factors and final reported concentrations are separate fields. Reapplying a factor to a finalized result can multiply an amount twice and create a serious magnitude error.
Translation failure: A final 0.040 mg/L result is multiplied by a listed factor of ten again. First ask what physical quantity this term denotes. A chemical name, a concentration, a limit and a quality-control status all occupy different roles in an analytical record. English fluency can hide a category mistake, especially after a table has been extracted from PDF into plain text. A good translation makes the role visible before attempting to make it sound elegant.
Practical repair: Check the column’s definition and retain the laboratory’s official final concentration rather than recomputing an ambiguous field. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Uranium and isotope notation
The standard’s title explicitly includes selected elements and uranium isotopes. An isotope-resolved result has an identity different from an aggregate elemental result. Chemical mass concentration and radiological activity or human dose are not interchangeable quantities, even when uranium is involved.
Translation failure: A uranium concentration row is labeled “radiation dose” in a translated medical or environmental summary. Check the upstream record that gives this field meaning. A laboratory number is attached to an analyte, sample, method, preparation state and reporting convention. When those connections are lost, a plausible phrase can become scientifically false. Reconstruct the connections before choosing a target-language equivalent, then keep them in the final page.
Practical repair: Preserve each isotope notation and the original unit, and refer any health or exposure interpretation to an appropriate qualified authority. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Chromium species versus elemental chromium
An elemental chromium measurement cannot by itself identify chromium(VI) or another chemical species. Different forms can have different significance in specific regulatory settings. Similar distinctions arise for arsenic species and other analytes when the source specifies chemistry beyond elemental identity.
Translation failure: Cr 5 µg/L is rewritten as Cr(VI) 5 µg/L without a speciation result. An abbreviated source often tempts editors to supply the sentence they think the author intended. That is where evidence can be fabricated. If the source is ambiguous, retain the ambiguity clearly or request clarification; do not fill missing data with a familiar textbook value, a default threshold or a convenient assumption.
Practical repair: Keep the unqualified elemental symbol and flag any request for a species-specific compliance statement as needing separate evidence. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Precision, uncertainty and decision rules
Measurement uncertainty describes limits on the reported estimate; a legal maximum describes an external acceptance rule. These quantities are not synonyms. A result close to a criterion may require a specified decision rule before a regulator or purchaser can make a defensible conclusion.
Translation failure: The laboratory reports a concentration near a limit, and the translation declares a universal pass. Think about the next reader, not only the original translator. The value may travel into a procurement spreadsheet, environmental disclosure, government query or internal monitoring chart. A short qualification removed at translation time can become an apparent fact downstream. Keep distinctions explicit enough that an excerpt remains defensible.
Practical repair: Separate the measurement, uncertainty, criterion, jurisdiction and decision authority, preserving each without giving the translator an invented approval role. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Making the multilingual report traceable
Sample collection and station identity
The numerical result belongs to a collected sample, location, matrix and time. Upstream and downstream stations, wells, container labels and report revision IDs are essential to reconstructing evidence. A correct chemical translation attached to the wrong station remains materially wrong.
Translation failure: The translated table swaps the IDs UP-03 and DN-03 while copying every analyte value correctly. Compare numerical data in the rendered PDF and the editable file. The wrong symbol, header or decimal separator can change meaning without producing a spelling error. For technical reports, visual proofing is part of semantic proofing: the layout tells readers which value belongs to which element, location and unit.
Practical repair: Match identifiers and collection information against the issuer’s record and preserve leading zeros, dates and directional codes. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Rounding and significant figures
Rounding changes the way precision is communicated. A certificate may report 0.0047 mg/L, while a commercial summary displays 0.005. The rounded figure may be convenient, but it must not replace a certified source measurement without permission or clear editorial identification.
Translation failure: A localization platform rounds all trace-element values to two decimal places, making several low concentrations appear as 0.00. Separate the source evidence from any explanation added for teaching. It is legitimate to explain unfamiliar notation in a translator’s note, but not to rewrite the laboratory’s result as if the explanation were measured. Label the original figure and any calculated, inferred or externally sourced interpretation as different kinds of statements.
Practical repair: Preserve source digits and units; display simplified values only in a clearly labeled derived summary with appropriate caveats. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Mixed reporting units in one table
A laboratory may use µg/L for trace elements and mg/L for relatively abundant elements. It may also place blanks, controls and sample results on adjacent pages. A blanket unit replacement or reflowed PDF can make separate values appear directly comparable when they are not.
Translation failure: A calcium row in mg/L inherits the µg/L header of the previous page. A translation checklist should look for an authority boundary. Laboratories measure, regulators apply rules, clients define purchasing criteria and translators preserve meaning. Those responsibilities may meet in the same document, but a target-language phrase should not transfer one actor’s power to another. This is particularly important when a reader is looking for a simple pass or fail.
Practical repair: Inspect the final document visually, repeat headers where needed and verify each analyte–result–unit–qualifier combination. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Laboratory revisions and corrections
A laboratory can issue a revised certificate to correct its own errors or add information. The translator should preserve both the new revision marker and the provenance of the underlying report. Quietly replacing an old page can confuse reviewers trying to establish what was available at a given date.
Translation failure: A customer receives revision B but the translated cover still identifies revision A. Read the report as a chain of decisions. The sample is collected, prepared, measured, qualified and reported; only afterward may someone compare it with a criterion. If a translation jumps directly from an isolated figure to a product or health conclusion, inspect which evidentiary steps were skipped and restore the missing scope.
Practical repair: Reconcile the report number, revision, date and attachments before release, and keep an auditable record of corrections. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Regulatory values are not built into the method
ISO 17294-2 describes measurement of selected elements; it does not provide one global statement of drinking-water acceptability. National limits depend on jurisdiction, water category, regulatory date and sometimes chemical form. Standards for a method and standards for a decision have separate functions.
Translation failure: A water sample measured using ISO 17294-2 is automatically labeled “ISO certified safe.” First ask what physical quantity this term denotes. A chemical name, a concentration, a limit and a quality-control status all occupy different roles in an analytical record. English fluency can hide a category mistake, especially after a table has been extracted from PDF into plain text. A good translation makes the role visible before attempting to make it sound elegant.
Practical repair: Publish the data as laboratory evidence; add legal interpretation only with an explicitly identified criterion and authorized source. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Final verification before release
A readable target summary without overclaiming
The final translation should make analyte, fraction, unit, reported value, limit and sample identity easy to find. Readers should also see whether the number is measured, estimated, bounded or missing. A readable report is not one that hides uncertainty; it is one that shows why the statement is appropriately limited.
Translation failure: An editor removes qualifiers to make the chart more attractive to consumers. Check the upstream record that gives this field meaning. A laboratory number is attached to an analyte, sample, method, preparation state and reporting convention. When those connections are lost, a plausible phrase can become scientifically false. Reconstruct the connections before choosing a target-language equivalent, then keep them in the final page.
Practical repair: Prefer a complete sentence such as “Arsenic was reported at 3.4 µg/L for sample W-18 under the stated method and conditions,” without inventing a public-health verdict. Before approving the page, read the complete original sentence, table header and adjacent note together. A well-formed target sentence should be equally precise about what is known and what is still conditional; readability is useful only if the underlying evidence remains intact.
Worked examples of consequential translation errors
Arsenic scale error
Original: “As 3.4 µg/L, site W-18.” Faulty rendering: “As 3.4 mg/L.”
The number appears unchanged, but it now means one thousand times as much. That error can distort a comparison to any monitoring threshold. The correct English rendering preserves µg/L, or explicitly identifies 0.0034 mg/L as a calculated conversion. A reviewer should confirm the value against the signed laboratory report, not merely against a copied spreadsheet.
The repair must be visible in the final published document, not only in the translator’s working notes. When an organization relies on bilingual records, the result should be checked by a reviewer who can compare each original number and qualifier directly with its destination cell. Keep approval and amendment history so users know which version supports the decision they are making.
A non-detect becomes zero
Original: “Cd <0.10 µg/L.” Faulty rendering: “Cd = 0 µg/L.”
The first is a bounded statement; the second asserts a precise zero concentration. The laboratory may have reached a reporting threshold without establishing absence. Restore the inequality and the relevant legend. If a public summary is required, say the element was below the stated reporting limit rather than promising that none exists.
The repair must be visible in the final published document, not only in the translator’s working notes. When an organization relies on bilingual records, the result should be checked by a reviewer who can compare each original number and qualifier directly with its destination cell. Keep approval and amendment history so users know which version supports the decision they are making.
A filtered result becomes total concentration
Original: “Dissolved lead in filtered sample: 2.1 µg/L.” Faulty rendering: “Total lead in water: 2.1 µg/L.”
The sample fraction has been changed. Suspended material is not necessarily represented in the original result. Restore the filtered and dissolved qualifiers and any digestion reference. If a contractual criterion requires a different fraction, that is an additional analytical requirement, not a translation preference.
The repair must be visible in the final published document, not only in the translator’s working notes. When an organization relies on bilingual records, the result should be checked by a reviewer who can compare each original number and qualifier directly with its destination cell. Keep approval and amendment history so users know which version supports the decision they are making.
A quality-control percentage becomes a pollution level
Original QA line: “Spike recovery 96%.” Faulty public chart: “Pollution 96%.”
Recovery is a metric of analytical performance after a known addition; it does not describe the percentage of contaminated water. Keep the item in the quality-control section with its actual title. Never merge a QC metric into the environmental results series to make a chart appear more complete.
The repair must be visible in the final published document, not only in the translator’s working notes. When an organization relies on bilingual records, the result should be checked by a reviewer who can compare each original number and qualifier directly with its destination cell. Keep approval and amendment history so users know which version supports the decision they are making.
Chromium becomes a specific species without evidence
Original: “Chromium (Cr), 5 µg/L.” Faulty rendering: “Hexavalent chromium 5 µg/L.”
An elemental result is not a speciation result. The new term could carry a different regulatory meaning, but no such chemical analysis is documented. Restore chromium (Cr) and query the issuing laboratory if a species-specific answer is needed.
The repair must be visible in the final published document, not only in the translator’s working notes. When an organization relies on bilingual records, the result should be checked by a reviewer who can compare each original number and qualifier directly with its destination cell. Keep approval and amendment history so users know which version supports the decision they are making.
Location and result become separated
Original: “UP-03 groundwater, 14 May, lead 1.2 µg/L.” Faulty rendering swaps the identifier to “DN-03.”
The numeric value and unit are copied correctly, yet they now identify the wrong monitoring location. Station codes are evidence keys, not words to localize freely. Check them against original table images, collection notes and report revisions before publishing.
The repair must be visible in the final published document, not only in the translator’s working notes. When an organization relies on bilingual records, the result should be checked by a reviewer who can compare each original number and qualifier directly with its destination cell. Keep approval and amendment history so users know which version supports the decision they are making.
Ten questions from translators and laboratory readers
Does ICP-MS itself certify drinking-water safety?
No. It is a measurement method; a water-safety finding also requires the relevant legal or technical criterion and its proper application.
What is 10 µg/L in mg/L?
It is 0.010 mg/L. A converted value should be distinguished from the laboratory’s original reported unit.
Can a less-than result be displayed as zero?
No. It is a reporting bound and should retain the laboratory’s limit and convention.
Does elemental chromium mean chromium(VI)?
No. Specific oxidation states or species must be established by appropriate analytical evidence.
Can drinking water and wastewater have the same LOQ?
They can, but one must not assume so. Matrix and method performance can affect the applicable limits.
Is spike recovery an environmental concentration?
No. It describes a control based on a known addition, usually expressed as a performance percentage.
Do uranium isotope results equal radiation dose?
No. Isotope identification, mass concentration, activity and dose are different physical and interpretive quantities.
Can a translator replace a 2016 ISO citation with 2023?
No. Preserve what the source says, and discuss later standard status in a clearly separate note.
What if the regulator requires dissolved metals but the report is total?
State the mismatch. Do not relabel the fraction; obtain a method-appropriate result or authoritative clarification.
