世界各地河流均被抗生素污染 非洲和亚洲最严重 1 Rivers around the world are contaminated(污染) with dangerous levels of antibiotics, according to a major new study. 一项新研究显示，世界各地的河流都被抗生素污染了，污染程度已经达到危险水平。 antibiotics [ˌæntɪbaɪ'ɒtɪks] n. [药] 抗生素；抗生学 Concentrations of antibiotics in some waterways exceed safe levels by 300 times, a global team of scientists led by the University of York found. 英国约克大学带领的国际科学家团队发现，一些河流的抗生素浓度超出安全值300倍。 exceed [ɪk'siːd; ek-] vt. 超过；胜过 The Thames was contaminated with five antibiotics, including levels of ciprofloxacin (环丙沙星)—used to treat skin and urinary tract infections(尿路感染)—that were three times what is considered safe. 泰晤士河被五种抗生素污染，其中用于治疗皮肤和尿路感染的环丙沙星水平超出安全值的两倍。 4 Researchers looked at 14 commonly used antibiotics in rivers flowing through 72 countries and found antibiotics were in two-thirds of samples. 研究人员在流经72个国家的河流中查找14种常用抗生素，并在三分之二的样本中发现了抗生素。 5 Scientists fear antibiotics in rivers cause bacteria to develop resistance meaning they can no longer be used in medicines for humans. The UN estimates that the rise in antibiotic resistance could kill 10 million people by 2050. 科学家担心河流中的抗生素会导致细菌产生抗体，这意味着这些抗生素不能再用作人类药物。联合国预计，对抗生素耐药性的上升会在2050年前导致1 000万人丧生。 bacteria [bæk'tɪərɪə] n.
