New research by the Canadian Health Department has identified traces of bisphenol A in the urine of 91% of Canadians. The study, known as the Canadian Health Measures Survey, tested for levels of 80 possible contaminants in urine and blood samples taken from people between the ages of 6 and 79 representative of the entire population.
The results have already been used by Canadian politicians to justify their recent banning of bisphenol A (BPA) in containers of infant foods. The Canadian initiative has caused a sea change in the attitude of public health watchdogs to the influence of endocrine disruptors such as BPA on the declining fertility rates of Western communities in North America, Europe and Oceania.
Given that BPA has a short life in the human body, the results indicate a major regular source of BPA in the North American environment. This has long been identified as coming from plastics used in can linings, plastic beverage containers and crown and screwcap seals on beverages, including wine and beer as well as soft drinks.
