	title = {Trace metals in rain at forested sites in the {Eastern} {United} {States}.},
	abstract = {Precipitation was collected intermittently between 1975 and 1982 as wetfall-only at four forested sites in the Southeastern United States and analyzed for Cd, Mn, Pb, and Zn. Mean concentrations at these rural sites were low.  Significant temporal and spatial trends were observed: all metal concentrations were higher during warm weather periods; concentrations of Cd and Pb decreased from 1976-1977 to 1980-1982; and for this later period Cd and Pb also exhibited significant differences in concentration among sites.  Manganese exhibited no significant trends. Metal concentrations in rain are negatively correlated with rainfall amount. We estimate that in-cloud aerosol scavenging dominates the long-term total wet deposition of these elements, but it is more important for Pb than for Cd and Mn.},
