Bisphenol-A harms children in all of the following ways EXCEPT______.
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.(1)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.(2)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
本题设题点在数字信息处。根据句(2)可知,疾控中心的一项研究表明,长期使用含双酚的塑料奶瓶的小孩,相当于每一千克的体重消耗13微克的双酚,因此,如果以这种方式喂养一个体重为10千克的小孩,他每天吃进去的双酚大概是130微克,故答案为[C]。
