第2012期:Experts call for tighter limits on chemical in water

'Forever chemicals' are used in a wide range of products from food packaging to make-up because of their water-resistant properties. “永久性化学物质” 因其防水的特性被广泛用于食品包装和化妆品等各类产品中。 UK water companies are required to test for 47 different types of PFAS. If levels are considered high risk, guidelines suggest the water isn't used for drinking purposes. 目前，英国各自来水公司按要求需对水中47种全氟和多氟烷基物质（PFAS）的含量进行检测。如果含量被认定为过高，根据英国饮用水监管局的指导方针，这些水则不可用作饮用水。 The Royal Society of Chemistry says this still exposes people to medium-risk levels and doesn't cover thousands of other types of PFAS. It wants tests for all PFAS and a tenfold reduction in the levels deemed acceptable, more in line with the US. 英国皇家化学学会表示，即便这样，人们仍会接触到一定量的有害物质，而且目前的检测并没有涵盖数千种其它类型的全氟和多氟烷基物质。该机构希望可以对水中所有类型的全氟和多氟烷基物质进行检测，并将饮用水中全氟和多氟烷基物质含量的最高限量降低十倍，更加接近美国的标准。 词汇表forever chemicals 永久性化学物质food packaging 食品包装make-up 化妆品water-resistant 防水的PFAS “per-and polyfluoroalkyl substances” 的缩写，全氟和多氟烷基物质guidelines 准则，指导方针exposes 使…暴露于tenfold 十倍的deemed 被视为in line with 与…处于同等水准
