摘　　要：采用Dustmate粉尘监测仪对马鞍山市远离交通影响的校园和市内交通道路旁空气悬浮颗粒物的污染特征进行了研究。城市道路空气悬浮颗粒物浓度有明显的日变化特征,道路旁空气悬浮颗粒物质量浓度在白天出现了一个峰值,可能是由于道路清扫所引起的。对清扫时机动车道旁和人行道上的颗粒物浓度进行的监测显示:道路人工清扫时引起的PM10及PM2.5质量浓度均高于国标或美国标准的许多倍,道路清扫对城市道路空气悬浮颗粒物浓度的影响不可轻视。The distribution characteristics of atmospheric suspended particulates in campus far from the road traffic and urban roadside were investigated with Dustmate in Ma＇anshan city.Concentration of urban road atmospheric suspended particulates takes markedly diurnal variation feature,a particulate concentration peak suspected during the day was observed,which may result from road sweeping.Road side in-site observation during road sweeping showed that the concentrations of PM10 and PM2.5 were many times those specified in GB 3095—1996 and NAAQS.The impact of urban road sweeping on atmospheric suspended particulates should not be neglected.
