摘    要:为调查马鞍山市城区主干道近地面空气质量状况,马鞍山市环境监测中心站于1999年1月19日~1月21日对城区3条主干道的5个监测点近地面空气质量进行了监测.结果表明,在城市整体环境空气质量良好的情况下,交通干道近地面空气污染较严重,主要污染源是机动车尾气,NOx、CO、TSP是特征性污染物,其中NOx平均分布浓度与车流量近似成正相关,从时间分布上看,NOx平均分布浓度早上最高,晚上次之,中午最低.指出,为改善城市的环境空气质量,必须加强对机动车尾气的监督管理.

关 键 词:主干道  近地面空气质量  机动车尾气  马鞍山市

Abstract:From January 19, 1999, to January 21,1999, the near ground air quality of three urban main roads and five monitoring sites in Maanshan were monitoring by Maanshan Environmental Monitoring Center in order to investigate the state of near ground air quality of urban main roads. Monitoring results indicated that near ground air of urban main roads was heavy polluted. Main pollution sources was motor vehicle exhaust, NO X, CO,TSP were the characteristic pollutants. According to time sequence, concentration of NO x was highest in morning , second in noon, and lowest in evening. It should strengthen the supervision and management of motor vehicle exhaust to improve urban air quality.
Keywords:Main road  Near ground air quality  Motor  vehicle  exhaust  Maanshan
