摘要
Abstract
The physicochemical composition and emission sources of sus-pended particles sampled at roadside was investigated. Suspended particles (total suspended particles (TSP) and PM10) were sampled on the weekend and on weekdays during four consecutive seasons. Water-soluble ionic species and metallic contents of suspended particles were further analyzed and used to identify the emission sources of suspended particles. Field sampling of suspended particles indicated that PM10concentration on weekends was higher than that on weekdays, while TSP concentration did not vary much between weekdays and weekend. PMl0 was contributed from the long-distance transportation of non-traffic pollutants as well as the emissions of local road-traffic sources, while TSP mainly related closely to the emissions of local mad-traffic sources. The results from chemical anal-ysis showed that the most abundant metals found in roadside suspended particles were Ca,Fe and Al,while the most abundant ions were SO42-,NO3-、NH4+. In addition, both source apportionment and backward tra-jectories indicated that the major sources contributing to suspended parti-cles sampled at roadside were vehicular emissions and fugitive road dust. However, the upwind non-traffic sources also contributed a noticeable portion of roadside suspended particles.关键词
