The hormone-disrupting herbicide atrazine is contaminating nearly 25%, or about 860,000 miles, of all continental US rivers at levels that can harm wildlife and may threaten human health, a new review of federal records has found.(一项对联邦记录的最新审查发现，干扰激素的除草剂莠去津正在污染美国本土近25%的河流，约86万英里，其浓度可能危害野生动物，并可能威胁人类健康。)
一项对联邦记录的最新审查发现，干扰激素的除草剂莠去津正在污染美国本土近25%的河流，约86万英里，其浓度可能危害野生动物，并可能威胁人类健康。
The waterways cover over 20% of surface drinking water intake(取水口)s across the country, and over 675,000 private and commercial well(水井)s.
这些水道覆盖了全国超过20%的地表饮用水取水口，以及超过67.5万口私人和商业水井。
Atrazine can have severe impacts on human and animal hormone(激素)s, especially for developing children. It was found to “chemically castrate(化学阉割)” frogs, and cause some to change sexes. The herbicide is so dangerous that it has been effectively banned in 60 countries, including the European Union, since 2003.(这种除草剂极其危险，自2003年以来已在包括欧盟在内的60个国家被实际禁用。) Litigation in the US seeks to strike down(推翻、废除) its approval, but it remains the second most widely used pesticide(农药) here, with about 70m pounds sprayed on the nation’s cropland annually.
莠去津会对人类和动物的激素产生严重影响，对发育中的儿童尤其如此。研究发现，它会“化学阉割”青蛙，并导致一些青蛙改变性别。这种除草剂极其危险，自2003年以来已在包括欧盟在内的60个国家被实际禁用。美国有诉讼试图推翻其批准，但它仍是美国第二大常用农药，每年约有7000万磅喷洒在全国农田上。
