Why not polycarbonate & BPA?
The basic unit that makes up polycarbonate is Bisphenol A, originally synthesized in the 1930’s as an oestrogen for pharmacological use. The fragility of the structure of these bonded units results in significant leaching of Bisphenol A into a variety of substances. Bisphenol A has been shown to be an endocrine disruptor and to simulate the action of oestrogenic compounds. There is also evidence that Bisphenol A enhances growth of human breast cancer cells. Bisphenol leaching is considerably greater in polycarbonate that is scratched, cloudy, or exhibits wear of any sort. Heating also accelerates the leaching process.
