PM2.5监测的微粒分级技术及测定方法的介绍

Introduction to Separation Techniques and Concentration Measurements for PM2. 5 Monitoring

把PM2.5纳入空气质量常规监测体系将对空气质量评价产生重大影响,通过环境立法旨在促进人为源微粒的控制与减排。PM2.5的监测涉及微粒分级及浓度测定两个方面,对微粒分级及测定方法的应用进展进行综述,为专业技术人员加深理解PM2.5及选择合适的监测方法提供参考。

In China, great impacts will take place on the air quality evaluation system when PM2. 5 is brought into the routine air quality monitoring through environmental leg islation. Particulate matters separation and concentration measurement are the two main steps in PM2. 5 monitoring. In this paper, separation techniques and measurements are analyzed and summarized, which provides references for deep comprehension of PM2. 5 and the selection of suitable monitoring measures.
