Introduction – Why This Testing Matters
Heavy metals such as lead, cadmium, chromium, mercury, and arsenic may be present in textile and leather products due to dyes, pigments, or raw materials.
These metals are toxic and can cause serious health issues including organ damage, neurological disorders, and skin irritation.
What is Heavy Metals Testing?
Heavy metals testing is used to detect and quantify toxic metals in textile and leather products.
Common metals tested include:
- Lead (Pb)
- Cadmium (Cd)
- Mercury (Hg)
- Chromium (total & Cr VI)
- Arsenic (As)
Why is This Testing Important?
Key Reasons:
- Protect human health
- Ensure compliance with regulations
- Prevent toxic exposure
- Required for global trade
Risks of Non-Compliance:
- Product bans
- Regulatory penalties
- Certification failure
- Health hazards
Applicable Standards & Regulations
- EU REACH Regulation
- OEKO-TEX® Standard 100
- CPSIA (USA)
- Various international safety standards
Permissible Limits (Typical Industry Values)
Metal | Limit (mg/kg) |
Lead (Pb) | ≤ 90 mg/kg |
Cadmium (Cd) | ≤ 75 mg/kg |
Mercury (Hg) | ≤ 1 mg/kg |
Chromium (total) | Varies |
Arsenic (As) | ≤ 25 mg/kg |
Key Test Parameters
- Total heavy metals
- Extractable heavy metals (sweat/simulated extraction)
- Specific elemental analysis
Test Method Overview
- Sample digestion using acids (microwave digestion)
- Analysis using ICP-MS / ICP-OES / AAS
- Quantification of metal concentration
Who Needs This Testing?
- Textile manufacturers
- Leather manufacturers
- Exporters
- Footwear industry
- Retail brands and compliance teams
Conclusion
Heavy metals testing is essential to ensure that textile and leather products are safe for consumers and compliant with international regulations. Proper material selection and chemical control help minimize contamination risks.
