Bisphenol-A harms children in all the following ways EXCEPT
News Item 1
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. (6) 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. (7) 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.
选项
A、At least 13mg.
B、Nearly 13mg.
C、Nearly 130mg.
D、At least 300mg.
答案
C
解析
根据句(7)可知,疾控中心的一项研究表明,用含多酚的塑料奶瓶喂养小孩,会让小孩长期与这种化学物质接触,相当于每一千克的体重消耗13微克的多酚,因此,如果以这种方式喂养一个体重为10千克的小孩,他几乎每天吃进去的多酚是130微克,故答案为[C]。
