资源简介：
A 3.5-year study was conducted to determine the signifcance of atmospheric
deposition to the pesticide concentrations in runoff. Both wet and dry
atmospheric depostion were collected at six sites in the central San Joaquin
Valley, California. Wet deposition samples were collected during individual
rain events and dry deposition samples were collected for periods ranging from
three weeks to four months. Each sample was analyzed for 41 currently used
pesticides and 23 transformation products, including the oxygen analogs of nine
organophosphorus (OP) insecticides. Ten compounds in rainfall and 19 in dry
deposition were detected in at least 50% of the samples.
