城镇职工医疗保险_世界各地河道均被抗生素污染 非洲和亚洲最严峻

英国约克大学发起了一项河道研讨,对环球72个国度711个所在的河道水质举行检测,发明65%的河道抗生素浓度凌驾平安规范,最差的超标300多倍。泰晤士河被视作欧洲最清洁的河道之一,其多条支流被检测出含有最少5种抗生素。

抗生素污染是致使细菌发生耐药性的门路之一。一些发生耐药基因的细菌若是没有被抗生素杀灭,会继承流传耐药基因,一朝一夕,照顾耐药基因的细菌会越来越多,形成抗生素失效,后果不堪设想。

研讨人员称,非洲和亚洲的河道抗生素污染堪忧,欧洲、南美洲和北美洲的状态也不容乐观,抗生素污染已成为一个环球性问题

Rivers around the world are contaminated with dangerous levels of antibiotics, according to a major new study.

一项新研讨显现,世界各地的河道都被抗生素污染了,污染程度已到达风险程度。

Concentrations of antibiotics in some waterways exceed safe levels by 300 times, a global team of scientists led by the University of York found.

英国约克大学率领的国际科学家团队发明,一些河道的抗生素浓度超越平安值300倍。

The Thames was contaminated with five antibiotics, including levels of ciprofloxacin – used to treat skin and urinary tract infections – that were three times what is considered safe.

泰晤士河被五种抗生素污染,个中用于医治皮肤和尿路感染的环丙沙星程度超越平安值的两倍。

Researchers looked at 14 commonly used antibiotics in rivers flowing through 72 countries and found antibiotics were in two-thirds of samples.

研讨人员在流经72个国度的河道中查找14种经常使用抗生素,并在三分之二的样本中发明了抗生素。

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.

科学家忧郁河道中的抗生素会致使细菌发生抗体,这意味着这些抗生素不克不及再用作人类药物。联合国估计,对抗生素耐药性的上升会在2050年前致使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·盖泽传授通知《卫报》说:“我们在人类病原体中看到的许多抗性基因都来自周围情况中的细菌。”盖泽传授没有介入这项研讨。

Drugs get into rivers via human and animal waste, as well as leaks from wastewater treatment and drug manufacturing sources.

抗生素药物经由过程人体和动物排泄物进入河道,污水处理厂和制药厂泄漏的抗生素也会进入河道。

In one site in Bangladesh, levels of metronidazole – which is used to treat mouth and skin infections – were 300 times greater than what is considered safe. The most common antibiotic was a urinary tract infection antibiotic called trimethoprim, which was present in 307 of 711 sites tested.

在孟加拉国某地的河道中,甲硝唑程度超越平安值300倍。甲硝唑是用来医治口腔和皮肤感染的。最常见的抗生素是医治尿路感染的甲氧苄啶,在环球711处河道取样点中,有307处河水中都检测到了甲氧苄啶。

Scientists flew out 92 testing kits to partners across the world who took samples from local rivers. Researchers found Bangladesh, Kenya, Ghana, Pakistan and Nigeria were home to the most contaminated rivers. The team said that the safe limits were most frequently exceeded in Asia and Africa.

科学家向世界各地的协作机构分发了92套测试东西,用来从本地河道中提取样本。研讨人员发明,孟加拉国、肯尼亚、加纳、巴基斯坦和尼日利亚的河道是受抗生素污染最严峻的。研讨团队称,亚洲和非洲的河道超越平安局限的频次最高。

However, sites in Europe, North America and South America also had high levels of contamination showing that antibiotic contamination was a “global problem".

不外,欧洲、北美洲和南美洲的河道也查出高程度的抗生素污染,这说明抗生素污染是一个“环球性问题”。

Professor Alistair Boxall, from the York Environmental Sustainability Institute, said: “The results are quite eye opening and worrying, demonstrating the widespread contamination of river systems around the world with antibiotic compounds.

约克情况可持续发展研讨所的阿利斯泰尔·博克斯奥尔传授说:“研讨结果让人张口结舌,也让人觉得担心。研讨显现,世界各地的河川体系遭到抗生素化合物的大面积污染。”
