Abstract
The concentration of OPPs in fresh water, seawater and suspended particles were measured in Asan Bay, Korea from June 2004 to October 2005. During the samplingperiod, the highest concentrations of pesticides detected in freshwater and seawater were 12-3448ng/L for IBP, 3-1483ng/L for DDVP and 2-259ng/L for Diazinon. Mevinphos, Ethoprophos, Merphos, Parathion-methyl, Azynphos-methyl and Azynphos-ethyl were also frequently detected in freshwater and seawater with concentrations generally lower than 100ng/L The concentrations of OPPS generally decreased with increasing distance from the shore implying progressive dilution in the marine environment. The highest concentrations of IBP and Diazinon were odserved in August due to intensive application of these pesticides in the watershed. Adsorption of pesticides onto suspended particles was studied in Asan Bay. DDVP, Phorate, Sulfotepp, Diazinon and IBP appeared to have high adsorption capacity onto suspended particles.
