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。
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。
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1000万人丧生。
"A lot of the resistance genes we see in human pathogens originated from environmental bacteria,” Professor William Gaze, a microbial ecologist at the University of Exeter who was not involved in the study, told The Guardian.
英国埃克塞特大学的微生物生态学家威廉·盖泽教授告诉《卫报》说:“我们在人类病原体中看到的很多抗性基因都来自周围环境中的细菌。”盖泽教授没有参与这项研究。
pathogen['pæθədʒən]: n. 病原体;病菌
Drugs get into rivers via human and animal waste, as well as leaks from wastewater treatment and drug manufacturing sources.
