浅析重庆市机动车尾气对环境空气质量的影响

Investigation into Automobile Vehicle Exhaust Impacts on the Ambient Air Environment in Chongqing

通过重庆市交通路边监测站的长期在线监测,对交通干道环境空气质量进行了统计与分析。并与重庆市其他环境空气监测点进行分析比较得出,机动车尾气是造成重庆市环境空气污染的重要因素之一。同时结合国内外一些先进的预防和控制汽车尾气污染的方法,提出了合理的防治措施,以防止机动车尾气污染进一步蔓延。

The author conducted statistical analysis based on air quality data, which generated from long-term moni- toring for traffic roadside stations as well as ambient air quality monitoring stations in Chongqing. The study sug- gested that, vehicle exhaust, which mainly comprised by particulate matter, nitrogen oxides, carbon monoxide, ozone, and organic matter, contributes one of major factors for ambient air poIlution in Chongqing. Furthermore, the paper proposed some feasible prevention and control methods in dealing with automobile exhaust, both domestic and abroad. The paper concluded with some control measures which might suitable for local automobile exhaust mitigation and control.
