Is bisphenol A toxic? The past is controversial.
　　About bisphenol A as environmental hormones to discuss the matter, the Japanese Chemical Industry Association issued "on the issue of environmental hormone Q & a" has been recorded: the female hormone effect of bisphenol A in 1 per 100000 of female hormones to between 1 / 10000, it made little progress. Bisphenol A is a polycarbonate, epoxy resin, unsaturated polyester monomer, and PS is formed by the polymerization of styrene monomer.
　　By comparison of the above two molecular structures, they are not of the same kind. PS does not contain bisphenol A structure, it can not be contaminated with bisphenol A impurities. Society of the plastics industry in recent years has been funded by Harvard University risk analysis center made a study on the impact of bisphenol A, according to the findings that published in 2004: About bisphenol A will lead to male hormone secretion increased "evidence of a serious shortage of". At present domestic and foreign daily drinking pure water, mineral water used plastic bottles and baby milk bottle, high-grade drinking water cup is monomer polymerization of polycarbonate using bisphenol A and acetone, its health and safety are obtained national food health organization recognized. So on the PS foam plastic tableware containing bisphenol A material, will lead to the reproductive function of arrhythmia paradox, it is groundless statement.
