摘要
PM_(2.5)是当前大气重要污染物,对生态环境和人体健康均有较大的危害。论述了国内外PM_(2.5)的环境标准、分析方法、组分特征和来源。我国PM_(2.5)年平均标准限值为35μg/m~3,日平均标准限值为75μg/m~3;目前,PM_(2.5)浓度监测手段主要有手工监测、自动监测和遥感监测;PM_(2.5)的主要组分有水溶性阴阳离子、含碳组分、无机重金属元素等;PM_(2.5)的来源以机动车尾气、燃煤、扬尘为主。
PM_(2.5) is an important pollutant in the atmosphere,which is harmful to the ecological environment and human health. The environmental standards,analytical methods,component characteristics and sources of PM_(2.5) at home and abroad have been discussed. The annual average standard limit of PM_(2.5) is 35 μg/m~3 and the daily average standard limit is 75μg/m~3 in China.At present,the monitoring methods of PM_(2.5) concentration mainly include manual monitoring,automatic monitoring and remote sensing monitoring. The main components of PM_(2.5) include water-soluble anions and positive ions,carbon-containing components,inorganic heavy metal elements and so on. PM_(2.5) mainly comes from motor vehicle exhaust,coal combustion and dust.
