According to the following article by Time, and the study that it cites, several compounds of the chemical bisphenol - used in commonly-handled products like shopping receipts and plastic containers like bottles - are likely to be unsafe for humans, and coming into contact with them can cause adverse affects such as changing hormone levels.
That article states:
BPA has been shown to cause problems with human reproduction, metabolism, neurological function and a whole host of other problems.
Research on the health effects of BPF and BPS is still in its early stages — just because a chemical has the ability to behave a certain way in the body doesn't necessarily mean it's dangerous.
...before going on to warn consumers to stay away from products that contain all three, which seems contradictory.
An article from the Scientific American goes further, citing studies and experiments that the compounds have had adverse effects, both in vitro and in vivo on animal test subjects, and concludes that the industry is not adequately regulated:
These in vivo studies agree with in vitro studies claiming that BPS is a hazard. But the problem doesn’t stop with removing bisphenol S from the market as was done for bisphenol A. The problem, according to Kurrasch, lies in the lack of industry regulation. Currently, no federal agency tests the toxicity of new materials before they are allowed on the market.
Is the chemical compound BPA unsafe for humans?
Are the chemical compounds BPF and BPS likely to be unsafe for humans, and would consumers be justified in avoiding them?
