水环境优控污染物筛选研究进展

Research progress on screening priority pollutants in aquatic environments

随着社会经济的快速发展,大量污染物排放到水环境中,使得水环境污染和治理问题备受关注.明确水环境优控污染物是科学有序开展水污染治理的前提.本文综述了水环境优控污染物筛选的原则和常用技术方法,并分析了不同方法的优缺点.通过比较不同水环境体系优控污染物的筛选结果,发现不同系统的优控污染物名单具有较大差异,因此应根据各地不同的污染特征,制定因地制宜的优控污染物名单.此外,在传统污染物筛选工作的基础上,未来应加强对新污染物的监测和评估,及时更新优控污染物名单,为水环境的保护和治理提供更全面的决策依据.

With the rapid development of economy,a large amount of pollutants have been discharged into the aquatic environments,making the treatment of aquatic pollutants being one of the most concerned environmental problem.Screening priority pollutants is a prerequisite for the scientific and orderly control of pollution in aquatic environments.This paper reviews the principles and commonly used methods for screening priority pollutants in aquatic environments,and discusses the advantages and disadvantages of different methods.Significant differences were observed in the list of priority pollutants in different aquatic systems,indicating that it is necessary to generate a specific list of priority pollutants for different systems based on their pollution characteristics.Besides screening priority pollutants from traditional pollutants,the monitoring and assessment of emerging pollutants should be strengthened in the future.It is also necessary to update the list of priority pollutants in a timely manner to provide more comprehensive decision-making basis for the protection of aquatic environments and the treatment of pollutants.
