公路两侧大气污染防治研究进展

机动车尾气和轮胎磨损颗粒中含有大量有毒有害成分,这些颗粒物随着大气飘移在公路两侧沉降,造成土壤、天然水系和农作物等的二次污染。本文按照ISO对大气污染的定义,给出公路两侧大气污染的定义,从污染现状、来源、危害、分布规律及影响因素等方面入手,综合评述目前公路两侧大气污染的研究成果。

Research Progress of Air Pollution Control Along Road Sides

There are lots of poisonous and harmful compositions in the exhaust of motor vehicles as well as in the tire wire particles,which will lead to the secondary pollution of soil,natural water and crops when drifting and settling along the road sides.The definition of air pollution on both sides of the road was given according to the meaning of atmosphere contamination in ISO.And the research achievement of present air pollution along roadsides was reviewed comprehensively from aspects such as current situation,origin,detriment,distribution and influence factors of the contamination.
