Bisphenol A
Better known as “BPA†has been suspected of being hazardous to humans since the 1930’s. It has been said that even at low levels BPA can act as an Endocrine Disruptor which means that it interacts with hormone receptors and can interfere with reproduction, development, and other hormonally mediated processes. Long term health concerns point to Chronic Toxicity.
There have been over two hundred studies published all raising health concerns about BPA just since 1997. The studies have suggested everything from developmental toxicity, carcinogenic effects, heart disease, diabetes, and abnormally high levels of certain liver enzymes, and possible neurotoxicity (BAD news) to even Obesity and of course Cancer. Other ill effects may include brain damage including but not limited to; memory, learning, and mood.
Environmental Impact of plastic bottles
As an environmental contaminant BPA interferes with the way certain plants and trees break down nitrogen (think-breath). According to Environment Canada, even at low levels, BPA can harm fish and other organisms.
Identification in Plastics
Type 7 is the catch-all “other” class for plastic. Some type 7 plastics, such as polycarbonate (sometimes identified with the letters “PC” near the recycling symbol) and epoxy resins, are made from Bisphenol A monomer. When such plastics are exposed to hot liquids, Bisphenol A leaches out 55 times faster than it does under normal conditions at up to 32 ng/hour.
