摘要:	Atmospheric aerosol particles and metallic concentrations were monitored at the Experimental Farm of Tunghai University (EFTU) sampling site in this study. Total suspended particulate matter (TSP) was collected by using a PS-1 sampler at the farm-sampling site, in central Taiwan, from July 2001 to April 2002. At the same time, PM2.5 and PM2.5-10 were also measured with a Universal sampler from January 2002 to April 2002. Only subjects with the most complete data records on TSP sampling (N=43) and PM10 sampling (N=23) were used in this analysis. Taichung Industrial Park, Taichung Kang Road (traffic) and a Hospital Incinerator surround the Experimental Farm of Tunghai University. Atmospheric concentrations of metallic elements were analyzed by a flame atomic absorption spectrophotometer (AA-680/G). The results indicated that the metallic elements Mg, Cu and Mn were the largest components in the TSP fraction; the metallic elements Fe and Cd were the largest composition in the PM2.5-10 fraction; however, the metallic elements Pb, Zn, Cr and Ni were the largest abundance in the PM2.5 fraction. The atmospheric metallic elements in the TSP, PM2.5 and PM2.5-10 fractions came different emission sources, such as soil, traffic, industry and resuspended particles. ? 2002 Elsevier Science B.V.
