New research presented in Washington in June has shown that exposure to bisphenol A (BPA)– a chemical found ion plastics – causes abnormal heart activity in women. It is the oestrogen receptors that are responsible for this effect in heart muscle cells.
BPA is an environmental pollutant with oestrogen activity, and is used to make hard, clear plastic and is commonly used in many plastic food containers, including water bottles.
Even low doses of BPA markedly increased the frequency of arrhythmic events the researchers found and it was made worse when exposed to estradiol, the major oestrogen hormone in women.
BPA is already linked to neurological defects, diabetes and breast and prostate cancer.
