Synthetic compounds — technically called per- andpolyfluoroalkylsubstances or PFAS, but commonly known as “forever chemicals” — have been used for decades in industrial and consumer products, from waterproof fabrics and firefighting foams to non-stick cooking pans. They accumulate in the environment due to their chemical stability, potentially posing a threat to human and animal health.
合成化合物——技术上讲是全氟和多氟烷基物质或称全氟烷基化学品，也是人们通常所知的通常所知的“永久化学品”——几十年来一直在工业和消费品中广泛应用，包括防水织物、消防泡沫和不粘锅等。由于其化学稳定性，它们会在环境中累积，可能对人类和动物的健康造成威胁。
Chemists from Northwestern University in Illinois and the University of California Los Angeles have developed an inexpensive, low-energy process thatbreaks downtwo of the most important classes of PFAS into harmless chemicals. The discovery was published in the journal Science on Thursday.
来自伊利诺伊州西北大学和加州大学洛杉矶分校的化学家们开发了一种廉价的、低耗能的工艺，可以将两种最重要的全氟烷基化学品分解成无害的化学物质。这一发现于周四发表在《科学》杂志上。
Exposure to PFAS depresses the immune system, decreases infant andfoetalgrowth and increases the risk of kidney cancer in adults, according to a report by the US National Academies of Sciences, Engineering and Medicine published last month. It also found evidence that suggested links with other cancers.
根据美国国家科学、工程和医学研究院上个月发表的一份报告，接触全氟烷基化学品会抑制免疫系统，阻碍婴儿和胎儿的生长，并增加成年人患肾癌的风险。报告还发现这种物质与其他癌症有关的证据。
The process, which the scientists say marks a breakthrough, involves heating PFAS to about 100C withsodium hydroxideindimethyl sulfoxide, a common solvent. This sets off a series of reactions that destroys the otherwise unbreakable chemical bonds between carbon andfluorineatoms that make PFAS so stable. The products are harmless, small organic molecules and fluoride ions
科学家们说这一过程标志着一种突破，该过程是用氢氧化钠在二甲亚砜（一种常见的溶剂）中把全氟烷基化学品加热到大约100℃。翻译划线句，长按文末小程序码打卡，答案下期公布~其产物是无害的小型有机分子和氟离子。
Water companies can filter PFAS out of drinking water but the chemicals then need to be disposed of — and the only methods available today involve high temperatures or pressures.Incinerationmay release some PFAS into the air, while burying them in landfills is “just guaranteeing that you will have a problem 30 years from now because it’s going to slowlyleach out”.
自来水公司可以将饮用水中的全氟烷基化学品过滤掉，但是这些化学品需要被处理掉——而目前唯一能用方法就是高温或高压。焚烧可能会将一些全氟烷基化学品释放到空气中，而将它们埋在垃圾填埋场“只是保证问题在30年后出现，因为它会慢慢从土地中渗出”。
