同位素示踪法在大气颗粒物重金属污染溯源中的应用进展

Application progress of isotope tracer technique for clarifying the origins of heavy metals in atmospheric particulate matter

近年来,大气颗粒物污染问题备受关注。大气中重金属等污染物与颗粒物结合在一起,随其进行迁移,危害生态系统和人类健康。对大气颗粒物重金属来源进行解析是治理的必要前提。概述了大气颗粒物重金属来源分析方法,重点综述了当前同位素示踪法在大气颗粒物重金属溯源中的应用现状,并对该领域的研究前景进行了展望。

Pollution of atmospheric particulate matter has caused great attention recently. Heavy metals and other pollutants in air may be bonded with atmospheric particulate matter. These pollutants migrate with atmospheric particulate matter, causing side effects to ecosystem anf human health. Source analysis of the heavy metals in particu- late matter is an effective way to deal with the pollution. This study summarized the methods of source analysis for heavy metals of atmospheric particulate matter. Emphasis of this study focused on the present application status of isotope tracer technique for clarifying the origins of heavy metals in atmospheric particulate matter. Research pros- pects were also proposed.
