What’s in your wallet? Another ‘estrogen’
A chemical cousin of bisphenol A, a hormone mimic, has turned up on banknotes from around the world in addition to tainting 14 other types of papery products. Owing to the near ubiquity of BPS in paper, human exposure is likely also “ubiquitous,” conclude the study's authors. Oh, and a second new study shows that BPS behaves like an estrogen.
