Abstract:
Objective To understand the total suspended particulates(TSP)in ambient air and their characteristics on metallic elements in Xi an.Methods 96air samples were collected from the industrial area,industry-traffic mixed area,heavy traffic area and control area in Xi an during the heating season and unheating season,2001.The concentra-tions of TSP in ambient air and the contents of Pb,Mn,Cr,Ni,Cd in inorganic extracts of TSP were determined.Re -sults The concentration of TSP in ambient air(0.5865mg /m 3 )during heating season was significantly higher than that(0.3535mg /m 3 )during unheating season(P
