BPA’s A is Bisphenol– an origanic synthetic compound with two hydroxyphenyl groups, it has been used since 1957.
Bisphenol A- are certain plastics and epoxy resins, BPA based plastic is clear and tough it is made into a variety of common consumer goods, such as water bottles, sports equipment, cd’s, and dvd’s. Epoxy resins containing BPA’s are used to line water pipes and coating on the inside of many food and beverage cans, and also in making thermal paper such as that used in sales receipts. In 2015 there was 4 million tonnes of BPA chemical produced for manufacturing polycarbonate plastics.
BPA inhibits estrogen mimicking hormone like properties that raise concern about it’s suitability in some consumer products and food containers. BPA is unsafe to the point that governments across the world have banned it, however the US and Canada only banned BPA for baby bottles and infant formula packaging. What about the rest of the plastics that contain BPA?
The FDA says that at current levels it is safe which occurs in the food, the European Food Safety Authority (EFSA) reviewed the new data and experts concluded that it is unsafe for humans. The EFSA will not revise their opinion that the known levels of exposer to BPA is safe.
Patricia Hunt a geneticist and Tim A. Osswald an expert in polmar engineering at the University of Wisconsin they both agree that the BPA in plastics can work themselves free, when the plastic is heated whether it’s a Nalgene bottle in a dish washer or a food container in the microwave, or a test tube being sterilized in an autoclave.
In recent years dozens of scientists around the globe have linked BPA to a myriad health problems such as, mammary and prostate cancer, genital defects in males, early on set of puberty in females, obesity, and even behavior problems such as attention- deficit hyper activity disorder.
Hunt focuses on aneuploidy, which is an abnormal number of chromosomes in eggs that causes birth defects, and miscarriages. Hunt exposed pregnant mice to BPA just as the ovaries in their developing female fetuses were producing a life time of eggs, when the exposed fetuses became adults, 40% of the eggs were corrupted we’re actually affecting three generations simultaneously Hunt said.
