自然水环境中抗生素的污染现状、来源及危害研究进展

随着现代分析技术的发展和人们环境安全意识的增强,抗生素等新兴有机污染物在自然水环境中的出现已引起广泛关注。简述了不同自然水体中抗生素的污染现状,分析了自然水环境中抗生素的主要来源和环境危害。分析表明:抗生素在近海海域和河流中的检出频率和浓度均高于湖泊和地下水中的值,这可能是由于人类活动以及污水排放在海洋与河流中较其他水体更频繁所致;污水处理厂出水是自然水环境中抗生素出现的重要来源之一,而抗生素在污水处理厂的去除率与其自身物理化学性质和污水处理工艺有关。

OCCURRENCES,RESOURCES AND RISK OF ANTIBIOTICS IN AQUATIC ENVIRONMENT: A REVIEW

With the development of modern analysis technologies and the enhanced consciousness of people for environmental security, occurrence of antibiotics as emerging organic contaminants (EOCs) in the environment have received growing global concerns. The present paper reviewed the pollution status of antibiotics in varied waters and analyzed the source and environmental risks of antibiotics in the aquatic environment. Results reveal that both detection frequencies and concentrations of antibiotics in coastal waters or rivers are higher than those in lakes and underground waters, which was probably due to the more frequent human activities and wastewater discharge from wastewater treatment plants (WWTPs) in the former. Wastewater discharge from WWTPs is considered one of the main resources of antibiotics present in the aquatic environment. And the antibiotics removal efficiencies in WWTPs are related to physicochemical property of antibiotics and treatment processes used in WWTPs.
