Bisphenol A (BPA) is primarily used for the manufacture of polycarbonate and epoxy plastics. Polycarbonate plastic is used in products such as CDs, DVDs and dental materials. It can also be used in plastic bottles and lunch boxes. Epoxy plastic can be used in electronics, building materials, in adhesives as an internal protective coating in canned food products and bottles of fizzy drinks, and in the renovation of water and waste pipes. Bisphenol A is also present in thermal paper which is used for receipts and tickets.
Bisphenol A is a endocrine-disrupting substance found in almost all human urine and blood samples. This indicates that for most of us low doses of the substance enter into our body all the time. This takes place primarily in the food of form and drink which has been in contact with polycarbonate or epoxy plastic, since traces of bisphenol A can leach from the material.
Bisphenol A is banned in baby bottles throughout the EU. Sweden has its own ban on bisphenol A in food packaging for children up to three years of age. The Swedish Chemicals Agency has proposed that bisphenol A be banned in thermal paper used in such products as receipts and tickets.
