KEY TAKEWAYS

100% Market Contamination: Hazardous substances were detected in every product tested. While individual doses may be low, the "cocktail effect" of daily, multi-source exposure poses severe long-term risks to endocrine health and fertility.


The Bisphenol Crisis: BPA and its substitutes-the most documented endocrine dis-ruptors-were nearly universal, found in 177 of 180 samples. Their high concentrations highlight a critical failure to curb toxins affecting human hormonal system in consumer structural plastics.


A Market-Wide Failure: Premium brands offer no guarantee of safety. Toxic substances, including unregulated flame retardants, are pervasive across the entire market, proving that price is not a proxy for chemical safety.


The "Toxic Legacy": Current regulatory gaps allow dangerous additives to poison the secondary raw material market. This makes safe recycling impossible and undermines the EU Circular Economy objectives. We urge EU policymakers to abandon the "substance-by-substance" approach and implement comprehensive bans on chemical classes to prevent regrettable substitution and ensure safety is a market standard, not a consumer burden.
