Chemical Exposure Classes

The article rejects the idea that BPA-free labeling reliably indicates safety because BPA is often replaced with similar bisphenols. BPS is described as at least as toxic as BPA and possibly more toxic. The original mandate is characterized as benefiting the chemical industry at public health's expense. Bisphenols function as estrogen mimics that raise circulating estrogen levels. Handling thermal paper receipts can substantially increase bisphenol body burden, especially when lotion is on the hands. The California mandate made endocrine-disrupting flame retardant chemicals standard in nearly every US mattress. Perchlorate primarily targets thyroid function, with other effects framed as secondary to thyroid dysfunction. Flame retardants in mattresses are linked in the article to cancer, endocrine disruption, and children's behavioral problems. Paraben toxicity is cumulative because exposures from different products add together. Oxybenzone crosses the placenta and is linked to negative birth outcomes. Children are presented as especially vulnerable to flame retardants because exposure sources include toys, clothing, bedding, and furniture. Modern flame retardant formulations are d…
