The European Commission has announced a ban on the use of the chemical Bisphenol-A in plastic baby bottles. There has been international concern over its use for some time, with Canada declaring Bisphenol-A toxic in September. The commission is acting on fears that Bisphenol-A (BPA) harms children. Scientists say the chemical can interact with children's hormone systems in such a way that it affects healthy growth, body function and immune response. BPA is one of the most widely produced chemicals worldwide, among its uses, from food packaging to baby bottles. A study for the Center for Disease Control found that babies fed this way were the most exposed to the chemical, consuming up to 13 micrograms of BPA each day per kilogram of body weight.
