摘　　要：为了解上海浦东地区冬季大气PM_(2.5)和PM_(10)污染特征和状况,以上海第二工业大学作为监测点进行了为期3个月的连续自动监测,并对污染物进行了分析。结果表明,监测时段内该地区空气污染情况较为严重,PM_(2.5)和PM_(10)日均浓度均超过我国现行的国家空气二级质量标准浓度限值。根据污染物形态和成分分析结果,综合气象、地理因素可见:该地区大气颗粒物污染以外部输入为主,本地道路扬尘、汽车尾气等对其也有较大的贡献;污染物中含有多种重金属元素,对空气质量和人体健康危害较大。To investigate the pollution characteristic of PM2.5 and PM10 in the area of Shanghai Pudong in winter, a continuous automatic monitoring was taken for 3 months which set the Shanghai Second Polytechnic University as the monitoring point. The pollutant was analyzed then. The results showed that the air pollution in this area in the monitoring period was quite serious. The minimums of the daily average concentrations of PM2.5 and PM10 were much more than the current national secondary air quality standard con- centration limit. The main pollutant of the atmosphere particles was input from outside based on the analysis results of the pollutant＇s morphology and composition, combined with the factors of the weather and geography. The raise dust from the local roadway and the automobile exhaust were also had major contribution. There were various heavy metal elements in the pollutant and with more harm to the atmosphere quality and human health.
