BPA exposure estimates wrong, say US researchers




New experiments by researchers at the University of Missouri (UM) show that exposure to the controversial chemical Bisphenol A (BPA) through diet has likely been underestimated by previous lab tests. In the new study, appearing in Environmental Health Perspectives, the researchers compared mice given a steady diet containing BPA to mice given a single exposure […]

Sperm quality found to plummet with BPA exposure




In the first human study of its kind, University of Michigan (UM) researchers have found that the controversial plastics chemical Bisphenol A (BPA) appears to be linked to decreased sperm quality and concentration. Several previous studies have documented adverse effects of BPA on semen in rodents, but none are known to have reported similar results […]

Plastic chemical BPA found to induce epigenetic changes




Scientists from Yale have shown how exposure to the ubiquitous chemical bisphenol A (BPA) induces epigenetic changes in pregnant mice that trigger hormonal imbalances in the later life of female offspring. BPA is an estrogen-like chemical that is a common component of plastics used to contain food. It is also used in baby bottles, refillable […]

Decomposing plastic refuse releasing BPA into oceans




Plastic waste in the ocean isn’t just unsightly and a danger to marine animals. Scientists have now found that certain plastics breakdown rapidly in the ocean, releasing a heady cocktail of toxic chemicals such as bisphenol A (BPA) which is known to interfere with mammalian reproductive systems. In the first study to look at how […]

Fresh concerns about BPA




Common assumptions about the controversial chemical bisphenol A (BPA) may be wrong, with new research showing that high levels of BPA remain in the body even after fasting for as long as 24 hours, suggesting that BPA exposure may come from non-food sources, or, that BPA is not rapidly metabolized, or both. The new research […]

Experts demand FDA act on BPA report




In the latest issue of the Journal of the American Medical Association, researchers from the Peninsula Medical School in the UK report a significant relationship between urine concentrations of the environmental estrogen bisphenol A (BPA) and cardiovascular disease, type 2 diabetes and liver-enzyme abnormalities. Used in the manufacture of plastic consumer products such as baby […]
