It is a key ingredient in polymers that are used to make adhesives, containers, electronic coatings, boat hulls.
The plastic monomer and plasticizer bisphenol A (BPA) is one of the highest volume chemicals produced worldwide.
"Risk-Based Green Screen Assessment of Bisphenol A" (PDF). They also found that BPA produced estrogenic effects in cells at levels 5 to acknowledgement phd thesis husband 10 times lower than those used for safety assessments by companies that manufactured polycarbonate plastics. Other EDCs, such as DDT and diethylstilbestrol, have been associated with congenital (birth) defects, reduced fertility, and diseases such as obesity, diabetes mellitus, and cancer in humans. Retrieved Wittcoff, Harold; Reuben,. 35 BPA binding to ERR- preserves its basal constitutive activity. BPA has also been discovered to exert very subtle effects on sexual behaviour in animals. Various conditions were found to facilitate the leaching process, including photochemical breakdown, exposure to high temperatures, the presence of ethanol, and the age of the plastic or resin.
Bisphenol A based plastics have been in commercial use since 1957. Studies employing standardized toxicity tests used globally for regulatory decision-making indicate that the levels of BPA in humans and the environment are below levels of potential concern for adverse effects. Molecular and Cellular Endocrinology. Fetal brain development Environmental exposure to BPA has the potential to affect the developing brain during gestation, according to research.
