Bisphenol A (BPA) is the basis for plastics such as polycarbonates and is found in consumer goods such as baby bottles, plastic microwave food containers and canned food and beverage linings. On October 2008, Canada became the first country to formally declare BPA hazardous to human health, due to its links with a wide range of health disorders from infertility, breast and prostate cancer, to thyroid malfunction, attention deficit syndrome and recurrent miscarriage. It is commonly found in PVC and PS plastic packaging (cordial bottles, yoghurt tubs) and in the lining of canned food tins.
