Food containers negatively affect fertility for three generations
When scientists exposed pregnant mice to levels of bisphenol A equivalent to those considered safe in humans, three generations of female mouse offspring experienced significant reproductive problems, including declines in fertility, sexual maturity and pregnancy success, the scientists report in the journal Toxicology and Applied Pharmacology.
Bisphenol A, an industrial chemical, is found in polycarbonate plastics used in food and drink packaging, and in epoxy resins, which coat the insides of some food containers and plumbing pipes. Thermal paper receipts and dental sealants also may contain BPA.
A national study found detectable levels of BPA in 93 percent of 2,517 human urine samples tested in 2003-04, suggesting that most of the U.S. populace is regularly exposed to the chemical. BPA also has been detected in human ovarian follicular fluid, placental tissue and fetal plasma, said University of Illinois comparative biosciences professor Jodi Flaws, who led the new analysis. According to the National Institutes of Health, the primary route of human exposure to BPA is diet.
