不过我在WIKI上的青春期条目 https://secure.wikimedia.org/wikipedia/en/wiki/Puberty 中发现这么一段: Bisphenol A(BPA) is a chemical used to make plastics, and is frequently used to make baby bottles, water bottles, sports equipment, medical devices, and as a coating in food and beverage cans. Scientists are concerned about BPA's behavioral effects on fetuses, infants, and children at current exposure levels because it can effect the prostate gland, mammary gland, and lead to early puberty in girls. BPA mimics and interferes with the action of estrogen-an important reproduction and development regulator. It leaches out of plastic into liquids and foods, and the Centers for Disease Control and Prevention(CDC) found measurable amounts of BPA in the bodies of more than 90 percent of the U.S. population studied. The highest estimated daily intakes of BPA occur in infants and children. Many plastic baby bottles contain BPA, and BPA is more likely to leach out of plastic when its temperature is increased, as when one warms a baby bottle or warms up food in the microwave.[48] 中文对Bisphenol A 的解释 https://secure.wikimedia.org/wik ... A%E7%94%B2%E7%83%B7 中有这么一段: 酚甲烷为一种内分泌干扰素,会影响生殖系统。在清洁聚氯乙烯、环氧树脂和聚碳酸酯纤维时,若使用氧化钠、氢氧化钠(苛性钠/哥士的)和其它碱清洁剂,会释出酚甲烷。 有关酚甲烷对人类的影响,目前说法不一:工业界资助的研究结果倾向于声称没有发现重大影响;政府资助的研究倾向于发现有重大影响。欧洲及日本学者已密切注视它对人类生殖力的影响。美国政府卫生机构称,动物实验显示,塑料瓶中通常含有的化学物质双酚A可能会引发癌变和其他功能紊乱。在实验中,接触到双酚A的老鼠身上出现乳腺癌、前列腺癌等癌症发病征兆。[1] 加拿大政府已于2008年10月18日发表公报宣布,被广泛应用于食品包装工业的双酚A是一种危险的化学品,并正式将双酚A列入有毒化学品名单,禁止在制造婴儿奶瓶的过程中添加双酚A。这一举措使加拿大成为全球首个宣布双酚A有害并禁止其用于食品包装业的国家。[2]
