拨开云中'雾':论PM2.5监测技术与形成机制的研究现状及发展

摘要

雾霾问题是现今中国经济社会发展进程中面临的一个重要挑战,如果长期得不到解决将会给中国带来越来越大的社会、经济负担.雾霾天气是一种大气污染状态,其中的PM2.5(直径小于等于2.5μm的颗粒物)则被认为是造成雾霾天气的"元凶".本文全面分析PM2.5的监测技术以及形成机制,并基于分析数据对PM2.5的监测及防治的发展提出指导意见.%Haze problem is an important challenge in the process of economic and social development in China today, and if it is not solved in the long term, it will bring more and more social and economic burden to China. Haze weather is a state of air pollution, and PM2.5 (particles with a diameter of less than 2.5 mu m) is considered to be the root cause of haze. This paper comprehensively analyzes the monitoring technology and formation mechanism of PM2.5, and provides guidance for the development of PM2.5 monitoring and control based on the analysis data.
