摘要
粤港澳大湾区水环境中抗生素残留问题较为严重,分析粤港澳大湾区抗生素污染特征及生态风险,可为未来该地区抗生素污染综合整治提供解决思路。首先,研究抗生素在粤港澳大湾区主要水环境介质中的时空分布特征及生态风险,确定磺胺类和喹诺酮类对水生态环境构成较大风险,应作为优先控制抗生素类型进行削减;其次,鉴于抗生素的污染源头以及环境行为,有必要开展粤港澳大湾区内饮用水源地、地下水和海水中抗生素污染状况等相关研究。在此基础上,提出港澳大湾区未来抗生素污染研究的重点关注区域和抗生素种类,并为抗生素耐药性的未来研究方向提出建议。
Background,aim,and scope The prevalent use of antibiotics,especially in human medicine,livestock and poultry farming,aquaculture,and plant disease treatment,has led to the accumulation of antibiotic residues in aquatic environments,causing severe environmental contamination.This phenomenon not only poses hidden harm to public health but also has a significant ecological impact on the structural and functional stability of aquatic ecosystems.Therefore,antibiotic pollution in the environment has become a focus of concern for the global environmental science community.Due to its rapid economic development,the Guangdong-Hong Kong-Macao Greater Bay Area(GBA)is facing severe problems of antibiotic pollution in the aquatic environment.This study aimed to analyze the pollution characteristics of five categories of typical antibiotics in different environmental media in the GBA,assess the ecological risks of these compounds in the aquatic environment,and provide research directions for the comprehensive management of antibiotic pollution in this region in the future.Materials and methods The results of published studies were summarized and organized to analyze the spatiotemporal distribution characteristics of,and ecological risks posed by,antibiotics in the water environment of the GBA.Results The detection levels of antibiotics in the water environment of the GBA are generally higher than those in other global regions,with sulfonamide and quinolone antibiotics in particular posing significant risks to the aquatic ecological environment in the GBA.Studies on the environmental behavior of antibiotics in different environmental media have shown that the main sources of antibiotic pollution in the rivers of the GBA are domestic sewage and industrial wastewater,while surface water and coastal aquaculture are important sources of antibiotic pollution in the surrounding seas.In addition to being widely present in rivers and lakes in the GBA,antibiotics have been detected at high concentrations in drinking water sources such as
