摘要：2005年对上海市闸北区空气中可吸入颗粒物(PM_(10)——空气动力学当量直径小于10μm的颗粒物的总称)的污染状况进行了一年的连续监洲。结果表明：全年各月PM_(10)污染均以2级为主,占总样本数的67．6％；其次是1级占20．O％,3级占11．0％,4级占1．4％。全年空气质量状况最好的为9月份,最差为11月份。PM_(10)浓度与CO和NO_2浓度呈现出显著的相关性,说明机动车尾气是该区域PM_(10)的主要来源；PM_(10)污染程度还明显地受到降水、气温、气压、风向、风速、相对湿度等气象条件以及北方沙尘暴的影响。
Ambient air pollution of Inhalable particle （PM10, Particles with aerodynamic equalivent diameter lower than 10μm） were monitored continuously in Shanghai Zhabei Area in 2005. Results indicated that, during the whole year, the monthly pollution level of PM10 stayed mainly class 2 with 67.6%, the second was class 1 with 20.0%, the third was class 3 with 11.0%, the fourth was class 4 with 1.4%. The seasonal variation showed that the best air quality occurred in September while the worst occurred in November. PM10 concentration con＇elated significantly to CO and NO2, which demonstrated that vehicle exhaust might be the predominate sources of PM10. It was also found that PM10 pollution was obviously associated with such meteorological conditions as precipitation, atmospheric temperature, atmospheric pressure, wind direction, wind speed and relative humidity, and external transportation like dust storm in north China .
