根据加拿大统计局的最新报告﹐大部分的加拿大人体内含有双酚A(bisphenol A)﹐91%的民众尿液有双酚A成分。
统计局在2007年到2009年间进行调查﹐得出上述数字。
加拿大人健康测量调查(Canadian Health Measures Survey)指出﹐12岁到19岁青少年体内的双酚A浓度最高﹐6岁到11岁的双酚A水平也比成年人高。
双酚A是化学物质﹐是聚碳酸酯纤维塑料的塬料﹐有替代人类雌激素的作用。
在加拿大人当中﹐体内双酚A平均含量为10亿分之1.16﹐大约超过体内天然雌激素水平的1000倍。
双酚A与心臟疾病﹑糖尿病及肝酵素上升有关联。过去3年以来﹐加拿大政府採取一些措施﹐减少双酚A﹐例如禁用聚碳酸酯质料製造婴儿奶瓶﹑将双酚A列入有毒物质名单。 |

双酚A(简称BPA),是世界上使用最广泛的工业化合物之一,是制造包括婴儿奶瓶、水瓶
