## Key Takeaways For Reviewing Plastic Content Data

- Independent review of laboratory data on plastic content requires evaluating method rigor and controls, not just particle counts from a lab report.
- Particle presence and chemical-additive presence are distinct questions; datasets testing for one cannot support claims about the other.
- Contamination is the central challenge in microplastics analysis, which makes documented blank controls essential for any defensible dataset.
- Validated methods have detection floors at 20–50 µm, so results cannot confirm absence of smaller particles or untested polymers.
- The Wellness Quality Institute provides independent verification of existing lab data against published criteria to support scope-locked public claims.

## Who This Guide Serves And How To Read It

This guide serves sustainability leads, founders, heads of marketing, brand directors, and procurement leads at US consumer brands. It is especially relevant for premium bottled water and functional beverage brands, baby and children’s product companies, supplement and powder brands, and health and wellness consumer packaged goods companies with a clean-label position that already make or plan to make a plastic-related claim.

Several technical terms appear throughout. Each has a plain-language definition.

- **Detection floor** is the smallest particle size or lowest concentration an instrument can reliably find. Anything below it is invisible to the method, whether or not it is present.
- **Blank control** is a sample that contains no target material, processed exactly like a real sample, to measure how much contamination the procedure itself introduces.
- **Spike recovery** is a test where a known quantity of plastic particles is added to a sample before analysis. The percentage recovered shows how well the method works in that specific product type.
- **Polymer panel** is the list of specific plastic types a test screens for. A test that covers five polymers will not detect a sixth.
- **Chain of custody** is the documented record showing who handled a sample, when, and under what conditions, from collection through analysis.
- **Reporting limit** is the lowest concentration a laboratory will formally report as a finding. Results below this level are typically recorded as “not detected,” even if trace signals exist.
- **Matrix** is the physical substance being tested, such as still water, sparkling water, or a liquid supplement. The matrix affects how well a method performs.

This guide focuses on water and similar simple-liquid products, where testing methods are most defensible. Food and complex product types sit outside this scope. The Wellness Quality Institute (WQI) serves US companies only, and its Plastic-Free Pathway Verification program is available nationally, including but not limited to California.

## Two Separate Questions Every Plastic-Content Dataset Must Answer

Every plastic-content dataset answers either a particle question or a chemical-additive question, and mixing them creates confusion.

The first question asks whether plastic particles such as fragments, fibers, or films are physically present in the product. The second asks whether chemical additives associated with plastics, such as phthalates and bisphenols, are present. These questions relate to each other, yet they remain distinct. One focuses on what plastics are made with. The other focuses on the particles plastics break into.

![Fragments of plastic suspended in blue water below the surface.](https://cdn.aigrowthmarketer.co/1784829388732-c6255482b477.webp)**Plastic doesn't disappear — it fragments. These secondary microplastics are the breakdown products of everyday objects, and independent research now detects them across the water supply. Detection, though, establishes presence, not absence.**

The evidence base for endocrine-disrupting chemicals such as phthalates and bisphenols is far more developed than the evidence base for microplastic particles themselves. Phthalates and bisphenols are well established as endocrine-disrupting compounds, with evidence from animal models, human clinical observation, and epidemiology, as documented in the [Endocrine Society’s scientific statement on endocrine-disrupting chemicals](https://pmc.ncbi.nlm.nih.gov/articles/PMC2726844/). Evidence for physical microplastic particles as a direct health hazard is newer, based on smaller samples, and methodologically contested in several key studies. Claims about particles should not borrow the confidence that belongs to claims about chemical additives.

Health language in this field needs careful hedging. Studies suggest potential associations between plastic exposure and certain biological responses. No responsible reading of the current literature supports causal claims. The [World Health Organization’s 2019 assessment, *Microplastics in Drinking-Water*](https://www.who.int/publications/i/item/9789241516198), found low concern for three potential hazard routes on the limited evidence available. It also stressed that this conclusion rests on incomplete information and that more research is urgently needed.

A dataset that tests for particles cannot support claims about chemical additives, and a dataset that tests for additives cannot support claims about particles. Knowing which question your data answers is the first step in knowing what claim it can support.

## The Contamination Problem In Practice

Contamination is the central challenge in microplastics analysis and explains why a lab report without documented controls does not qualify as a defensible dataset.

A blank control is a sample that contains no target material, typically filtered water or an equivalent clean matrix, processed through every step of the analytical procedure alongside real samples. Its purpose is to measure how much plastic the procedure itself introduces so that number can be subtracted from sample results. Without a blank control, you cannot tell whether a finding came from the product or from the gloves, air, reagents, or laboratory equipment.

![Scientists in white coats working with samples and microscopes in a laboratory.](https://cdn.aigrowthmarketer.co/1784829434095-0fc8fbcf29fa.webp)**Only a small number of laboratories can genuinely test for microplastics, and capability varies by instrument and method. WQI reviews a company's existing third-party laboratory data against a defined standard — it does not run the tests itself.**

The contamination sources are specific and well documented. [Nitrile and latex gloves shed metallic stearate additives](https://microplasticsolution.com/post/are-we-counting-gloves-or-plastic-the-error-of-2-000-particles-that-is-shaking-up-the-science-of-mi), which are salts of fatty acids used as release agents in glove manufacturing, and these have long hydrocarbon chains spectrally similar to polyethylene, the world’s most common plastic. [Automated spectral matching software can assign confidence levels exceeding 90%](https://microplasticsolution.com/post/are-we-counting-gloves-or-plastic-the-error-of-2-000-particles-that-is-shaking-up-the-science-of-mi) to erroneous stearate-as-polyethylene identifications. Ambient air deposition is measurable. [Procedural blanks across the published microplastics literature have been found to contain between 7 and 511 particles](https://journal.winnowlabs.com/science/the-challenge-of-measuring-plastics-in-humans), with a mean around 80, according to a meta-analysis cited in [Ciornii et al., *Analytical Chemistry* (2025)](https://pubs.acs.org/doi/10.1021/acs.analchem.5c00847). Organic fats and biological material can also be misidentified as polymers, particularly in lipid-rich product types.

The practical consequence of inadequate blank controls appears clearly in one of the most-cited figures in this field. A [2024 study published in *PNAS* by Qian et al.](https://www.pnas.org/doi/10.1073/pnas.2300582121) reported approximately 240,000 plastic particles per liter in bottled water, with roughly 90% identified as nanoplastics. A [subsequent commentary in *PNAS*](https://www.pnas.org/doi/10.1073/pnas.2411099121) found that the study’s procedural blanks appeared contaminated and its quality control inadequate. The critique travels with the figure every time it is cited because the finding cannot be separated from the method that produced it. The critique focuses on blank controls, which are the same contamination controls that WQI’s standard, WQI-CS-01, requires.

For a deeper dive on what a rigorous independent data review examines, see [How To Conduct An Independent Microplastics Data Review](https://www.wellnessqualityinstitute.com/articles/independent-review-laboratory-microplastics-data/?utm_term=reviewing-plastic-content-lab-data&utm_campaign=ai_growth_agent). The key point for your own dataset is that without documented blanks, you cannot separate what the product contains from what the procedure introduced.

## Method Ranges And Detection Floors In Real-World Reports

State water boards have published two analytical methods for microplastics in drinking water, and their validated ranges define the practical boundaries of what any test can reliably report. These methods provide the most stringent public reference points available for this type of analysis, and organizations may choose to treat them as examples.

The SWB-MP2-rev1 Raman spectroscopy method is validated above 20 µm through 5,000 µm. The SWB-MP1-rev1 infrared spectroscopy method is validated above 50 µm through 5,000 µm. A regulatory definition of microplastics in drinking water reaches down to 1 nanometer. The best validated methods begin at 20 or 50 micrometers, which are thousands of times larger. The 1–20 µm fraction is not validated under either method, and everything below it currently sits beyond reliable commercial measurement.

![Colorful plastic fragments in water inside a laboratory petri dish.](https://cdn.aigrowthmarketer.co/1784829410323-fb401fc7b1e4.webp)**Microplastics are particles smaller than five millimeters. Current methods can count and identify them at the upper end of that range, but reliable measurement falls away as particles get smaller — a limit that shapes every honest claim.**

FTIR, which is infrared spectroscopy, and Raman spectroscopy give different answers on the same sample because they operate on different physical principles, have different detection floors, and perform differently across particle sizes and product types. Neither method is universally superior. Each has specific strengths and failure modes. A result produced by one method is not directly comparable to a result produced by the other without documented method-equivalence review.

“None detected” means none were found above that instrument’s detection floor, for the polymers it screened, in the lot it tested. This is a bounded statement rather than a guarantee of absence. A method that begins at 50 µm cannot see anything smaller, so “none detected” can coexist with particles being present below that size.

WQI’s review criteria align with published frameworks, and these method ranges are presented as published specifications rather than WQI’s own thresholds. When you review your own lab report, check whether the stated detection floor matches the method used. A result reported at 50 µm cannot support a claim about smaller particles.

## Interlaboratory Variability: Why The Same Sample Gives Different Answers

[The same material, tested by different accredited laboratories using published methods, can produce particle-count results that disagree by factors of two to ten](https://journal.winnowlabs.com/science/the-challenge-of-measuring-plastics-in-humans). This pattern does not automatically signal poor laboratory practice. It reflects the defining technical reality of the microplastics field.

The most rigorous demonstration of this reality is the [84-laboratory interlaboratory comparison conducted by the Versailles Project on Advanced Materials and Standards (VAMAS)](https://journal.winnowlabs.com/science/the-challenge-of-measuring-plastics-in-humans), published as [Ciornii, D. et al., “Interlaboratory Comparison Reveals State of the Art in Microplastic Detection and Quantification Methods,” *Analytical Chemistry* 97, 8719–8728 (2025)](https://pubs.acs.org/doi/10.1021/acs.analchem.5c00847). [Identical reference samples were distributed to 84 participating laboratories](https://journal.winnowlabs.com/science/the-challenge-of-measuring-plastics-in-humans), and each laboratory used its normal analytical workflow. [Coefficients of variation across labs ranged from 45% to 129%](https://journal.winnowlabs.com/science/the-challenge-of-measuring-plastics-in-humans), which means the spread between laboratories was roughly half to one and a half times the mean value for a given reference sample.

The causes are specific. Laboratories use different instruments and methods, which produce different detection floors. Capability also varies within a single laboratory depending on which instrument and method are used. The VAMAS authors interpret this as a sign that the participating laboratories are not doing poor work. Instead, the field lacks standardized preparation protocols, reference materials, and validation infrastructure that would make results comparable across sites.

This finding has a direct consequence for how a dataset should be evaluated. The particle count itself is not the primary indicator of data quality. The method, the controls, and the documented performance of the laboratory against that specific method and matrix determine whether a dataset is usable. A high particle count from a poorly controlled study and a low particle count from a rigorously controlled one are not comparable. Neither can support a defensible public claim without independent review of the underlying method.

## The Controls Checklist: How To Audit Your Own Dataset

The following questions apply to any existing microplastics dataset before you draw conclusions about what it supports. A “no” or “unknown” answer to any question marks a gap that limits what the data can defensibly claim.

- Were blanks run, and were blank results reported?
- Were spike recoveries within an accepted performance window? (Published guidance such as [AOAC International](https://www.aoac.org/) offers recovery acceptance criteria as an example of a real laboratory performance standard.)
- Were replicates performed?
- Is there documented chain of custody?
- Is the data recent enough to reflect current production?
- Is the analytical method appropriate for the product matrix?
- Is the tested particle-size range stated?
- Is the target polymer panel stated, at minimum PE, PP, PET, PS, PVC, PA, PC, and PMMA?
- Are reporting limits adequate, or does a non-detect result lose meaning because the limits are too high?

Eurofins and EMSL Analytical are named in related WQI materials only as examples of laboratories with established microplastics capability in a thin market. They are not WQI-endorsed, approved, or preferred vendors, and they are not partners.

WQI qualifies laboratories by accreditation tier rather than by identity. ELAP-accredited laboratories for the applicable method are preferred. ISO/IEC 17025-accredited laboratories with the method and matrix explicitly in scope are accepted. Other qualified independent laboratories may be conditionally accepted through documented method-equivalence review and WQI technical approval.

For more on interpreting what lab results actually mean, see [Microplastics Lab Results: What The Data Actually Means](https://www.wellnessqualityinstitute.com/articles/independent-review-lab-results-microplastics/?utm_term=reviewing-plastic-content-lab-data&utm_campaign=ai_growth_agent).

## What A Reviewed Dataset Can And Cannot Support As A Public Claim

Detection can establish that a particle is present, but it cannot prove that no particles are present. Finding a particle is comparatively straightforward. The laboratory isolates it, confirms chemically that it is a polymer, and reports it. Proving that no plastic is present is a fundamentally different and far harder claim because it would require ruling out every particle below the detection floor, every polymer outside the tested panel, and every production lot that was not sampled.

A single good test result cannot stretch into a company-wide or product-line claim. As the Qian et al. study illustrates, a single striking figure gains meaning only when the method and controls stand up to scrutiny. Credible data turns into greenwashing when the claim outruns what the data actually shows.

The Wellness Quality Institute exists to close this gap. WQI is an independent verification body that reviews a company’s existing third-party laboratory data on plastic and microplastic content against WQI-CS-01. The review turns a lab report into a reviewed finding with approved claim language attached. WQI reviews existing data rather than running tests, does not certify products as plastic-free, and has no commercial stake in the outcome. That separation creates a level of credibility that a self-reported claim cannot reach.

Every Standard Met product receives a public registry entry with a registry ID that any customer, retailer, or journalist can check. Verification is scope-locked to the reviewed product, dataset, tested particle-size range, polymer panel, and production period. A Standard Not Met outcome is private. It carries no public claim, no logo rights, and no registry listing. It is never described as a failed product, and the company can resubmit with updated information.

A single assessment fee covers review, verification decision, and registry listing, with no separate mark-license or registry fee. Independent laboratory testing is arranged and billed separately by a qualified independent laboratory. Payment of the assessment fee does not guarantee a verification decision. The verification period is 24 months from the sampling date of the most recent accepted dataset.

The following table compares what a raw lab report provides against what a WQI-reviewed dataset provides.

| Attribute | Raw Lab Report | WQI-Reviewed Dataset |
| --- | --- | --- |
| **Interpretation** | Self-reported, and the market may view it as marketing | Independently reviewed against published criteria (WQI-CS-01) |
| **Claim Support** | Unclear, bounded by unknown method limits | Scope-locked claim language with required disclaimers |
| **Public Verification** | None | Public registry entry with a checkable registry ID |

A raw lab report carries a higher risk of greenwashing accusations because the market cannot verify the method behind it. A WQI-reviewed dataset reduces that risk by making the method and controls publicly checkable.

*WQI Plastic-Free Pathway Verification does not certify that a product contains zero plastic, microplastics or nanoplastics. It shows that the company is on a verified pathway toward plastic-free standards. Verification applies only to the reviewed products, submitted datasets, tested ranges, polymer panels, production or sampling periods, and supporting controls. WQI verification is not a California approval, government certification, or health or safety certification.*

## Where Independent Review Fits In Your Claim Strategy

WQI reviews existing data against published criteria rather than re-testing, so the client’s relationship with its laboratory stays the same. The review examines what the laboratory already produced, including the method, the controls, and the documented performance, and then determines what that dataset can defensibly support.

When a brand publishes its own test results, the market reads it as marketing regardless of how rigorous the underlying testing was. Self-reported results are structurally discounted because the party reporting them has an obvious interest in the outcome. Independent review by a body with no commercial stake in the result changes that dynamic.

The most common alternative to independent review is no independent review of plastic claims whatsoever. In that scenario, a company relies on self-reported lab results and internal interpretation and asks the market to trust it. Against that baseline, a scope-locked, publicly registered, independently reviewed finding becomes a materially different kind of claim.

## Frequently Asked Questions

### 1. What Does “None Detected” Actually Mean?

As explained earlier, “none detected” is a bounded statement. In practice, this means a report showing “none detected” for eight polymers at a 50 µm floor tells you nothing about nanoplastics or a ninth polymer type. Understanding these boundaries is the first step in knowing what a non-detect result actually supports.

### 2. Who Does The Testing?

A qualified independent laboratory performs the testing, not the Wellness Quality Institute. WQI reviews the resulting data, method, and controls against WQI-CS-01. WQI does not run tests, so the client’s relationship with its laboratory remains unchanged. WQI prefers ELAP-accredited laboratories for the applicable method, accepts ISO/IEC 17025-accredited laboratories with the method and matrix explicitly in scope, and may conditionally accept other qualified laboratories through documented method-equivalence review.

### 3. Is This A Certification?

This program is a verification of reviewed data and demonstrated progress toward plastic-free standards. WQI deliberately avoids the terms “certified” and “certification” for this program. A certification implies a settled, guaranteed state, and no such guarantee is scientifically available for plastic content claims. Verification describes what actually happened, which is an independent review of a dataset against a defined standard.

### 4. What Happens If Our Dataset Does Not Meet The Standard?

A Standard Not Met outcome is private. It carries no public claim, no logo rights, and no registry listing, and it is never described as a failed product. The outcome often reflects insufficient data, an unsupported method, or incomplete scope rather than anything about the product itself. The company may submit corrected or additional information for future review. Participating in the review process creates no public downside risk.

### 5. Does California Endorse This?

California has not created a consumer-product plastic standard and does not endorse the Wellness Quality Institute. WQI aligns its criteria with California’s drinking-water microplastics framework because it is the most stringent credible public reference available. This alignment does not mean California authorized, approved, or endorsed the program. A verification is not a California approval, a government certification, or a health or safety certification.

### 6. What Can We Say Publicly If We Are Verified?

A company whose dataset receives a Standard Met outcome may state that its dataset was reviewed and accepted under WQI’s Plastic-Free Pathway Verification standard. It may use the approved mark “WQI Plastic-Free Pathway Verified” for the specific products that met the standard and use approved result language tied to its Verification Scope. Every public claim links to the registry ID. Claims of “plastic-free,” “microplastic-free,” “zero plastic,” or “certified” are prohibited, as is extending a single product’s result to a product line or the whole company.

### 7. How Long Does Verification Last?

The verification period is 24 months from the sampling date of the most recent accepted dataset. After that period, continued claim use requires re-verification with current data. This reflects the reality of lot-to-lot variability, because a result reflects the production period it was drawn from. Expired registry entries remain publicly visible and marked “Expired,” so the record stays honest over time rather than quietly disappearing.
