摘要

Anthropogenic S emissions have been declining in eastern North America since the early 1970s. Declines in atmospheric S deposition have resulted in decreases in concentrations and fluxes of SO~2-_4 in precipitation and drainage waters. Recent S mass balance studies have shown that the outflow of SO~2-_4 in drainage waters greatly exceeds current S inputs from atoms- pheric deposition. Identifying the S source (s) which contribute (s) to the discrepancy in watershed S budgets is a major concern to scientists and policy makers because of the need to better under- Stand the rate and spatial extent of recovery from acidic deposition.
