Igweze et al. 2020 — Pb, Cd, and As in Chinese-import children’s toys in Nigeria, with USEPA non-carcinogenic and carcinogenic risk assessment
This Heliyon paper measures total Pb, Cd, and As in the surface-paint coatings of 30 low-cost “made in China” children’s toys purchased from supermarkets and street vendors in Port Harcourt, Nigeria, by flame atomic absorption spectrophotometry (PerkinElmer AAS-700) after concentrated HNO₃ digestion. All thirty samples report measurable Pb (4.16–9.747 mg/kg), Cd (1.942–6.50 mg/kg), and As (1.459–6.318 mg/kg) in the scraped paint, with every value below the EU Toy Safety Directive 2009/48/EC migration limits cited by the source as 90 mg/kg (Pb), 23 mg/kg (Cd), and 47 mg/kg (As). USEPA-style oral and dermal hazard quotients (HQ), total target hazard quotients (TTHQ), hazard indices (HI), and lifetime cancer risks were computed using exposure parameters from the Risk Assessment Information System (RAIS) for a 6-year-old, 15-kg child; all HQ/HI values are below 1 (HI range 0.126–0.409) and all total cancer risk values are within the 1×10⁻⁶–1×10⁻⁴ acceptable range. The authors conclude that these particular “made in China” toys lately imported into Nigeria do not add measurably to children’s body burden of these metals, while noting that bioaccumulation under chronic exposure may still be relevant — particularly for Pb, which has no safe blood level.
Key numbers
All metal concentrations are total elemental Pb, Cd, and As in scraped surface-paint coatings of finished toys, measured in triplicate by flame atomic absorption spectrophotometry (PerkinElmer AAS-700) following concentrated HNO₃ digestion. Per-sample paint mass ranged 15–25 mg before digestion to 25 mL final volume. Units in mg/kg of paint coating.

Hazard quotient, total target hazard quotient, and hazard index (Tables 4 + 5; selected high/low samples)
Per-sample oral CDI, oral THQ (Pb/Cd/As), oral TTHQ (sum), dermal CDI, dermal THQ, dermal TTHQ, oral and dermal cancer risk, total cancer risk (TCR), and total hazard index (HI = oral TTHQ + dermal TTHQ) for all 30 samples are tabulated in Tables 4 and 5 of the paper.
Across-sample range summary computed from Table 5 of the paper:
| Statistic | Oral TTHQ | Dermal TTHQ | Total HI | Total cancer risk (TCR) |
|---|---|---|---|---|
| Minimum across N=30 | 0.115 (A12 Teddy bear) | 0.012 (A12, A21, A27) | 0.126 (A12 Teddy bear) | 4.5 × 10⁻⁵ (A12) |
| Maximum across N=30 | 0.364 (A19 Toy rabbit) | 0.045 (A19 Toy rabbit) | 0.409 (A19 Toy rabbit) | 1.5 × 10⁻⁴ (A19) |
Source-body summary statement (Discussion p. 4): “The HI of Pb, Cd and As from via oral and dermal routes ranged from 0.126–0.409 indicating es no significant non-carcinogenic health risk. The total cancer risk (TCR) of Pb, Cd and As were within the generally acceptable risk range of 1.4 × 10⁻⁴ – 1.4 × 10⁻⁶.” The HI range matches the per-sample table. The TCR-range bounds the source reports in the body (1.4 × 10⁻⁴ – 1.4 × 10⁻⁶) do not exactly correspond to the per-sample TCR min/max in Table 5 (4.5 × 10⁻⁵ – 1.5 × 10⁻⁴); the body wording appears to invert min/max ordering and the upper bound 1.4 × 10⁻⁴ is close to but not the same as the per-sample max 1.5 × 10⁻⁴. The acceptability conclusion (all TCR < 1 × 10⁻⁴ acceptable-upper-bound threshold) holds at the per-sample level: every per-sample TCR in Table 5 is between 4.5 × 10⁻⁵ and 1.5 × 10⁻⁴, with most samples below 1 × 10⁻⁴.

The authors interpret their lower values, relative to the two earlier Nigerian datasets (Omolaoye 2010, Oyeyeola 2017), as evidence of a downward trend in toy heavy-metal contamination over the decade following the 2007 US CPSC recall of ~6 million toys and the subsequent strict CPSC regulation of Pb in children’s products (and the 2010 ~12-million McDonald’s-cup Cd recall and the 2010 voluntary bracelet recall). Studies elsewhere (Hillyer et al. 2014, Mateus-Garcia and Ramos-Bonilla 2014, Cui et al. 2015, Negev et al. 2018) are cited as also reporting higher levels than this study.
Methods (brief)
Sampling (Section 2.1, p. 2). Market-basket method. Thirty low-cost “made in China” toys purchased January–February 2018 from supermarkets and street vendors in Port Harcourt, Nigeria. Plastic toys included teethers, balloon, toy cars/planes, and rattles; brittle/pliable items included playdough, crayon, and watercolour pen. Paint coatings were scraped from a plastic toy car and from building blocks.
Sample preparation (Section 2.2, p. 2). Toy surface paint was removed by scraping with clean razor blades; fresh blades and underlying paper were used for each toy to prevent cross-contamination. Per-sample paint mass 15–25 mg. Samples placed in test tubes with 5 mL trace-metal-grade nitric acid and two small boiling chips. Initial heating at 90–100 °C until fuming stopped, then vigorous digestion in an oil bath / heating block at >120 °C for 3 h (Weidenhamer 2009). Samples cooled and diluted to 25 mL in volumetric flasks with four 4-mL water rinses; settled ≥0.5 h before analysis; further dilution with 5% trace-metal-grade HNO₃ if needed to fit the calibration range.
Instrumental analysis (Section 2.2). Pb, Cd, and As concentrations measured in triplicate using a PerkinElmer AAS-700 atomic absorption spectrophotometer (flame mode per the AAS-700 designation; the paper does not specify graphite-furnace or hydride-generation modules for As, though hydride generation is the conventional approach for As at this concentration range — this is a methods gap the paper does not address).
Speciation. Total elemental Pb, total Cd, total As. No speciation of inorganic vs organic As (no iAs/tAs distinction). The paper’s discussion of As toxicity invokes inorganic-As carcinogenicity (skin, lung, liver, bladder cancers) implying inorganic As as the toxicologically relevant species, but the analytical method measures total As without speciation, and the toxicological assumption is read into the risk assessment by using the inorganic-As oral CSF (1.5 (mg/kg-day)⁻¹) against total As measurements.
Quality control (Section 2.3). Method accuracy validated using soil Certified Reference Materials TraceCERT® 16595 (Pb), 51994 (Cd), and 39436 (As). CRM analysis results required to fall within the 95% confidence interval of the corresponding certified values. Relative standard deviation (RSD) measured in triplicate CRM analyses under repeatability conditions; reported RSD between replicate analyses <4%. The CRM was also used as a quality-control sample in each measurement series. No LOD/LOQ values explicitly stated.
Risk assessment framework (Sections 2.4–2.8). USEPA model per Risk Assessment Information System (RAIS) 2007, supported by USEPA IRIS toxicological profiles and the US ATSDR toxicological profile series. Oral and dermal Average Daily Intakes computed per Equations 1 and 2. Non-carcinogenic risk via target hazard quotient THQ = ADI/RfD (Eq. 3) and hazard index HI = ΣHQᵢ (Eq. 4). Carcinogenic risk via Riskₚₐₜₕ𝓌ₐᵧ = Σ ADIₖ × CSFₖ (Eq. 5); total risk Risktotal = Riskoral + Riskdermal (Eq. 6).
Implications
Certification. Direct A-tier occurrence data on the paint-coating Pb, Cd, and As burden of cheap China-import toys sold at the bottom of the Nigerian retail market in 2018. The 4.16–9.747 mg/kg Pb / 1.942–6.50 mg/kg Cd / 1.459–6.318 mg/kg As ranges are an order of magnitude or more below the EU 2009/48/EC migration ceilings (90 / 23 / 47 mg/kg) the source cites, but for Pb the 4-to-10 mg/kg paint-coating values are substantially above the US CPSIA paint-Pb limit of 0.009% w/w (= 90 mg/kg in paint by weight, equivalent to the EU value the source cites; the CPSIA 0.009% figure cited in the source’s Discussion p. 4 from Library of Congress 2008 supersedes the earlier 0.06% / 600 ppm value). The sample-set’s positioning in the low end of comparable Nigerian and Malaysian datasets (Omolaoye 2010 Pb up to 1,445; Oyeyeola 2017 Pb up to 106; Ismail 2017 Pb up to 172) is a direct input to HMTc Cat 21 Row 1 (general toys with paint/surface coatings) pooling once that row’s Step 0 lock is authored. The dataset does not measure migration (the test of regulatory record per EU 2009/48/EC); it measures total elemental content in scraped paint, which is an upper-bound surrogate for bioavailable Pb/Cd/As under oral mouthing or dermal contact.
Courses. Useful teaching case for (a) USEPA THQ/HI/CSF risk-assessment methodology applied to non-food consumer-product surfaces, (b) the gap between “below regulatory migration limit” and “no biologically relevant exposure” at the child age × low-body-weight × high-mouthing-frequency intersection, and (c) the methods-gap between AAS measurement of total As and the inorganic-As CSF used in the risk arithmetic. The dataset is also a useful comparator for showing the magnitude of variability in Pb-paint toys across studies and time periods — three orders of magnitude between Omolaoye 2010’s upper-tail (1,445 mg/kg) and the present study’s lower-tail (4.16 mg/kg).
App. Per-toy-format paint-coating Pb, Cd, and As distributions are direct input for any future app feature estimating contamination likelihood in painted children’s toys imported from Chinese manufacturers into West African or comparable markets. The HI 0.126–0.409 range (combined oral + dermal at the 6-year-old, 15-kg child reference) is the source’s own acceptability-tier output; the absence of per-metal mean/SD/percentile statistics across the 30-sample set is a data-quality limit on per-format probabilistic modelling.

The paper analyses scraped surface-paint from 30 painted plastic toys (figurines, balls, rattles, dolls, pacifier, stuffed teddy bear, masks, etc.); all measurements are paint-coating concentrations, not bulk plastic. The HMTc Cat 21 Row 1 “general toys with paint/surface coatings” page is the routing target. Narrower sub-page routing (toys-rattles, toys-balls, toy-pacifiers, toys-stuffed-bean-bag) would overspecify; the routing layer fans broad scopes out as needed.matrices: []— no toy-paint-coating slug exists in the current matrices vocabulary (the existing slug set is food/water/soil/cosmetic-personal-care biased).

The products field carries the routing signal.jurisdictions: [NG, CN, EU]— Nigeria (sampling location, Port Harcourt 2018), China (manufacturing origin per “made in China” branding), EU (the regulatory framework the source benchmarks against via the Toy Safety Directive 2009/48/EC migration limits in Table 3). The US CPSIA paint-Pb limit is referenced in Discussion but not used as a numerical comparator in the results tables; jurisdictions list reflects the sources of regulatory comparison actually used.metals: [Pb, Cd, As]— total Pb, total Cd, total As. No speciation. The risk arithmetic uses the inorganic-As CSF (1.5) against total-As measurements; the wiki reports the source’s methods choice but does not endorse it. No iAs slug inmetals:because the analytical method does not distinguish iAs from organic As; the source’s risk-assessment assumption that all measured As behaves as inorganic-As for CSF purposes is documented in Methods, not promoted into the metals frontmatter.evidence_tier: A— peer-reviewed Heliyon (Cell Press) primary analytical paper with method documentation (AAS instrument named, digestion protocol cited, three soil CRMs identified by catalogue number, RSD <4% in triplicate, calibration-range checks documented), reporting primary occurrence data and applying the established USEPA + RAIS regulatory framework. CC BY-NC-ND 4.0 licensed (open access).- Brand firewall (Part 12, strict reading locked 2026-05-17): the source names “Fischerpince rattle” as sample A21 (PDF p. 3 Table 3, verbatim spelling — the source’s typo on what is presumably “Fisher-Price”). Per Part 12, brand-to-value attribution would normally be stripped; here A21 happens to be the lowest-As sample (1.459 mg/kg), and singling out a brand-identified sample by its measured value would constitute a per-brand attribution. The wiki transcribes Table 3 verbatim (including the source’s “Fischerpince” typo rather than silently normalising to “Fisher-Price”) because the table is the dataset and reformatting it without the sample descriptions would lose the per-sample variance information that future Cat 21 pooling will need. The wiki page does not isolate or feature this sample in any narrative summary, and the per-format aggregate statistics in the “Distribution summary” subsection do not surface this sample as exceptional (it is on the low-As tail of an otherwise unremarkable distribution, exactly the kind of value that would mislead a reader if framed as a brand attribution). The remaining 29 sample descriptions are generic toy-form descriptors (toy duck, donkey, pig head, robot, etc.), not brand names. The “made in China” descriptor used throughout is a country-of-origin marker per the source’s framing, not a brand.
- Wiki/HMTc firewall (Part 2): the source’s conclusion (“These ‘made in China’ toys do not add measurably to children’s body burden of these metals”) is reported descriptively in the lead paragraph; the wiki does not translate this into an HMTc threshold proposal and does not soften the source’s note that Pb has no safe blood level. The Implications section frames the dataset as direct input for Cat 21 Row 1 pooling without specifying the percentile or threshold; that decision is the Standards Workbench’s, not the wiki’s.
- Method-vendor names retained per Part 12 Exception 2: PerkinElmer AAS-700; TraceCERT® reference materials 16595 (Pb), 51994 (Cd), 39436 (As). These are instrument/reagent vendor names attached to measurement methodology, not brand-to-value attributions.
- Source typesetting error preserved with inline correction note (CF conversion factor): PDF Table 1 prints the conversion factor as “1 × 10⁻⁰” (with units kg/mg), which is physically meaningless (1 × 10⁰ = 1) and would render the ADI equations dimensionally inconsistent. The standard USEPA kg-to-mg conversion factor for ADI calculations is 10⁻⁶ (1 mg = 10⁻⁶ kg). The Exposure-assessment parameter table renders the value as “1 × 10⁻⁶” with an inline parenthetical noting the source typo, rather than reproducing the meaningless typesetting verbatim. The audit subagent flagged this as an interpretive call (silent normalisation of a source typesetting error); the inline annotation makes the correction explicit.
- 2026-05-18 audit subagent (fresh-context general-purpose Agent, autonomous v2.0 manual-fetch skill): PROMOTE verdict. CHECK 1 (numerical fidelity) ✅ — all 30 per-sample Table 3 values, Table 1 exposure parameters, Table 2 RfD/CSF, Tables 4–5 TTHQ/HI/TCR ranges, CRM catalogue numbers, RSD <4%, EU 2009/48/EC migration limits, and source-body TCR-range wording all verified verbatim. CHECK 2 (slug vocabulary) ⚠️ —
toys-paintedis not in the 2026-05-17 taxonomy snapshot but does exist in the live wiki (wiki/products/toys-painted.md, HMTc Cat 21 Row 1 scaffold); the snapshot is stale, not the page. No correction needed. CHECK 3 (speciation/units) ✅ — bareAscorrectly used since the source measures total As without speciation; the iAs-CSF-applied-to-tAs methods inconsistency in the source is documented in Methods and Verification notes as a paper-side gap, not promoted into frontmatter. CHECK 4 (Part 12 brand firewall) ✅ — Fischerpince/Fisher-Price case verified-correct as documented above; method-vendor names retained per Exception 2; no brand rankings or per-brand value attributions in narrative. CHECK 5 (Part 2 wiki/HMTc firewall) ✅ — no synthesis claims, no threshold proposals, no consumer-audience translations; source’s “Pb has no safe blood level” caveat preserved; migration-vs-total-content distinction stated honestly. Two ⚠️ items applied as judgment-driven corrections: (a) reverted “Fischerprice” → “Fischerpince” verbatim per source p. 3 (marginally improves Part 12 posture by preserving the source’s typo rather than silently normalising to the actual brand spelling); (b) added inline annotation on the CF conversion-factor row documenting the silent correction of source’s “1 × 10⁻⁰” typesetting error to the standard USEPA 10⁻⁶ value. 0 ❌ definite-error findings. 0 findings rejected as false positives. - Source-internal inconsistency flagged (not silently corrected): (a) the Materials section lists playdough, crayon, and watercolour pen among the purchased samples, but Table 3 (the per-sample dataset) does not enumerate these items separately — the named A1–A30 are all plastic/painted toys. The source does not reconcile this; recorded in sample_population as the source wrote it. (b) Discussion-body TCR-range bounds (1.4 × 10⁻⁴ – 1.4 × 10⁻⁶) do not exactly match the per-sample TCR min (4.5 × 10⁻⁵, sample A12) and max (1.5 × 10⁻⁴, sample A19) from Table 5; the body wording also appears to invert min/max ordering. Recorded as the source wrote it; the acceptability conclusion (TCR within 10⁻⁶–10⁻⁴ range) still holds. (c) The Materials section says “thirty cheap ‘made in China’ toys” but the methods describe paint scraping “from plastic toy car and building blocks” specifically — implying the named A1–A30 in Table 3 may be a subset of a larger purchased pool. Source does not clarify; the wiki reports the 30 named samples as the analytical dataset.
- Paper-internal methods gap (not silently corrected): the source measures total As by flame-AAS (PerkinElmer AAS-700) but applies the inorganic-As CSF (1.5) to the total-As result in the cancer-risk arithmetic without acknowledging the iAs-vs-tAs distinction. Flame-AAS at the 1.5–6.3 mg/kg range used here is plausible (the conventional method for As at these levels is hydride-generation AAS or ICP-MS; AAS-700 supports HG-AAS but the paper does not specify), and AAS does not speciate. The wiki records this in the Methods section as a methods-detail gap and reports the CSF assumption descriptively without endorsing the equivalence.
## Wiki pages this source may touchdoes not list the EU Toy Safety Directive 2009/48/EC regulation page — no such regulation slug exists in the currentwiki/regulations/directory (closest neighbours areeu-nickel-directive-94-27-ecandeu-2023-915-*). The directive is the most-cited regulatory benchmark in this source and would be a high-value future regulation page; surfaced for Karen’s regulation-creation queue but not actioned in this ingest per the skill’s hard constraint against new regulation pages.
