空气中挥发性有机物的污染来源及防治措施分析

挥发性有机物(以下简称VOCs)是臭氧(O3)与二次有机气溶胶(organic aeroso)的前体物,经光化学反应生成O3和SOA等二次污染物,VOCs内部碳氢氧化物与氮化物在紫外线照射下产生臭氧,进而破坏臭氧层引起光化学烟雾,对生态环境、气候变化造成不同程度的影响;VOCs具有致癌性,对人体健康造成了严重危害。文章对空气中挥发性有机物的污染来源及防治措施进行讨论,对VOCs定义、分类及其危害进行了概述,结合挥发性有机物监测技术,提出解决挥发性有机物空气污染的相应对策。

Volatile organic compounds(hereinafter referred to as VOCs)are precursors of ozone(O3)and secondary organic aerosol.Secondary pollutants such as O3 and SOA are formed by photochemical reaction.Carbon hydroxides and nitrides in VOCs produce ozone under ultraviolet radiation,which destroys the ozone layer and causes photochemical smog,which has varying degrees of impact on the ecological environment and climate change.VOCs is carcinogenic and has caused serious harm to human health.This paper discusses the pollution sources and control measures of volatile organic compounds in the air,summarizes the definition,classification and harm of VOCs,and puts forward the corresponding countermeasures to solve the air pollution of volatile organic compounds combined with the monitoring technology of volatile organic compounds.
