环境空气和废气中二噁英类污染物的采集研究

Study on Collection of Dioxins in Ambient Air and Waste Gas

二噁英类污染物是一类持久性有机污染物,具有高毒性、难降解等特点,对环境和人体健康构成严重威胁。准确采集环境空气和废气中的二噁英类污染物是开展二噁英污染监测与治理的基础。本文综述了环境空气和废气中二噁英类污染物的采集方法,重点介绍了大气颗粒物和气态二噁英的采集方法,比较分析了不同采集方法的特点及适用条件,并探讨了采样过程中的质量控制措施。研究表明,采用合适的采样设备和采样方法,并严格控制采样质量,是准确获取二噁英污染数据的关键。本文可为环境空气和废气中二噁英类污染物的监测和管理提供参考。

Dioxins are persistent organic pollutants,which are highly toxic and difficult to degrade,posing a serious threat to the environment and human health.Accurate collection of dioxin pollutants in ambient air and waste gas is the basis of monitoring and controlling dioxin pollution.This paper reviews the collection methods of dioxins in ambient air and waste gas,focuses on the collection methods of atmospheric particles and gaseous dioxins,compares and analyzes the characteristics and applicable conditions of diff erent collection methods,and discusses the quality control measures in the sampling process.The research shows that the key to accurately obtain dioxin pollution data is to adopt appropriate sampling equipment and sampling method and strictly control sampling quality.This paper can provide reference for monitoring and management of dioxins in ambient air and waste gas.
