N2 - In China's largest city, Shanghai, dry deposition fluxes of Cd, Pb, As and Hg were 137, 19354, 2897 and 9.4μgm -2a -1, respectively in an urban area, intermediate in a suburban area, and 51.7, 5311, 1703 and 7.3μgm -2a -1, respectively in a rural area. Enrichment factors were Cd>Pb>As>Hg. Seasonal variations of metals differed: Pb and As were dominated by fossil fuel combustion, Cd was related to industrial pollution, and natural source controlled Hg levels.
