】阅读《塑料瓶装水真的干净吗》完成下面题目（7分）
①出门在外，口渴的时候我们都习惯买一瓶水喝，瓶装水给我们的印象是干净和方便，尤其是高档瓶装水都会标榜自己“出身清白”，“从未受到过人类污染”。例如,“王岛云雨”产自澳大利亚塔斯马尼亚岛,那里号称拥有世界上“最干净的空气”,雨水自然清洁无比；“公元前1万年”产自号称“地球上最古老的水源”——加拿大卑诗省沿岸的冰川，水质更是纯正无比。然而，科学家指出，塑料瓶装水也有可能“不干净”。
②英国化学研究人员威廉·肖迪克表示，装饮用水的塑料瓶生产过程就有污染隐患，因为在制造瓶子的过程中，会使用含有锑元素的化合物作催化剂，随着塑料瓶的成型，锑元素也进入了塑料中。塑料瓶可能会持续向瓶中的水溶解重金属元素锑,这种元素长期积聚在体内可能危害健康。威廉·肖迪克对当地的15种热销瓶装水进行化学检验，结果发现天然地下水中的锑含量是万亿分之一，而刚出厂的瓶装水的锑含量平均为万亿分之一百六十。时间越长，塑料瓶中的锑元素在水中的溶解量越大，这个过程就像泡茶一样。出厂3个月后，瓶装水中的锑元素的含量竟然增加了一倍。然而，现在市场上大多数瓶装水包装上注明的保质期大多是24个月。另外，温度越高，锑元素在水中的溶解量越大，而人们对瓶装水需求量较大的季节是温度高的夏天。肖迪克表示，虽然摄入极少量的锑元素不会导致人生病，但是大量摄入则会诱发呕吐，甚至可能致命。
③美国哈佛大学的研究人员米歇尔等人发现，不少塑料瓶在加工过程中会加入名为“双酚A”（BPA）的化学物质。这种化学物质与出生缺陷、发育问题、心脏病和糖尿病患病风险高有关联。专家对它可能对人体健康造成的影响表示担忧，而一些国家已将该物质正式列为有毒物质。
④此外，荷兰研究者发现，瓶装矿泉水经常被细菌和真菌污染，污染的瓶装矿泉水对健康个体致病的危险可能有限，但对于免疫功能低下的病人和婴儿，则有更高的感染危险。
⑤英国“水与环境管理协会”的执行主席尼克·里夫斯还表示，瓶装水对环境的污染也不容忽视。全世界每年用于制造塑料瓶的塑料为270万吨，这些塑料的原料大多是从石油中提取的，仅在美国，制造这些塑料瓶就要消耗150万桶石油，这些石油可以供10万辆汽车使用一年。86%的塑料水瓶最后都变成了垃圾，需要400年至1000年才能降解。这些塑料垃圾在燃烧时会产生有毒气体和含有重金属的灰烬。
（摘自2011年5月《知识就是力量》，略有删改）
A.随着温度增高，时间增加，塑料瓶中的锑元素在水中溶解量会越大。
B.重金属元素锑一旦被人体摄入，就会诱发呕吐，甚至可能致命。
C.全世界每年用于制造塑料瓶的塑料为270万吨，这些塑料的原料大多是从石油中提取的。
D.专家认为，在塑料瓶加工过程中所加入的名为“双酚A”（BPA）的化学物质可能对人体健康造成影响。
