摘要:The atmospheric particles near the ground in urban environment can influence human health directly. After collecting samples of TSP,PM10,PM2.5 at the height of 2 meters in Putuo, Qinpu, Minhang districts of Shanghai city, we research the temporal-spatial distribution of atmospheric particulates’ mass concentrations and its effect factors. Different grain size particles show characters of TSP>PM10>PM2.5, the spatial distribution characteristics of mass concentration of three districts are respectively Putuo>Qingpu>Minhang, Qingpu>Putuo>Minhang, Qingpu>Putuo>Minhang, the temporal distribution characteristics of TSP, PM10 , PM2.5 mass concentration are autumn & winter>spring>summer. PM10 and PM 2.5 account respectively 65-73%, 40-50% of total suspended particulates. Concentrations of atmospheric particles near ground level are controlled by atmospheric temperature, humidity, dust storms, pollution emission and other factors. The temperature, humidity are correlated negatively with particle concentration, the mass concentrations of dust storms samples are double of 10-day average concentrations of non-dust storm samples, and the dust storm event increase the mass concentration of Shanghai atmospheric particulates significantly. This study makes clear of spatial and temporal distributions of atmospheric particulates in Shanghai, and provides data for Environmental Protection Departments to take measures for protecting environment.
