New pollutants in river and lake water:Occurrence characteristics,ecological risks,and prevention and control measures
The frequency and types of new pollutants detected in rivers and lakes are increasing,including persistent organic pollutants,endocrine disruptors,antibiotics,microplastics and other new pollutants.Management of new pollutants has become one of the priorities of ecological environmental protection.Compared with traditional pollutants,new pollutants pose potential risks to the safety of river and lake ecosystems and the health of drinking water.China's new pollutant management started late in general,facing fewer technological monitoring means,the bottom of pollutants being unclear,lacking of better related prevention and control regulations etc.In this paper,the development of policies and action plans for new pollutants are sorted out,the characteristics and ecological risks of new pollutants in rivers and lakes are analyzed,the research progress on new pollutant prevention and control technologies in rivers and lakes is summarized,and new pollutant prevention and control strategies for rivers and lakes and methods for evaluating the effects of health risks are proposed,so as to provide a reference for the prevention and control strategies of new pollutants in rivers and lakes.
