Numerous scientific studies have shown various detrimental effects from exposure to bisphenol A (BPA).
The risks of exposure to this synthetic hormone are still being researched but may include such serious problems as reproductive system abnormalities, obesity, and early puberty.
Children and retail cash register workers may be at particular risk due to the vulnerability of the former and the high exposure to thermal receipts of the latter.
There are too many unknowns about the detrimental effects of BPA on human health to allow its continued under-regulated use. It's time for the US government to take steps towards banning its use in products to which consumers have direct exposure until such time that the substance's safety can be proven.
