Endocrine disruptor include DDT, polychlorinated biphenyls (PCB's), bisphenol A (BPA), polybrominated diphenyl ethers (PBDE's), and a variety of phthalates. In fact, almost all plastic products, including those advertised as "BPA free", have been found to leach endocrine-disrupting chemicals. In a 2011, study it was found that some "BPA-free" products released more endocrine active chemicals than the BPA-containing products. Other forms of endocrine disruptors are phytoestrogens (plant hormones). Xenoestrogens are a type of xenohormone that imitates estrogen. Synthetic xenoestrogens include widely used industrial compounds, such as PCBs, BPA and phthalates, which have estrogenic effects on a living organism. Alkylphenols are xenoestrogens. The European
Endocrine disruptor are appropriate", however this study was conducted over a year before the EPA announced the final structure of the screening program. The EPA is still finding it difficult to execute a credible and efficient endocrine testing program. As of 2016, the EPA had estrogen screening results for 1,800 chemicals. In 2013, a number of pesticides containing endocrine disrupting chemicals were in draft EU criteria to be banned. On the 2nd May, US TTIP negotiators insisted the EU drop the criteria. They stated that a risk-based approach should be taken on regulation. Later the same day Catherine Day wrote to Karl
