dc.description.abstract 아산만 해역의 유기인계농약 분포특성을 2004년 6월부터 2005년 8월까지 조사하였다. 조사 기간 동안 28가지의 유기인계 농약이 아산만에서 검출되었다. IBP는 표층수에서 가장 빈번하게 다량으로 검출되었다(최대 6,343.7ngl−1 ). DDVP, diazionon, ethoprophos, methidathion도 비교적 높은 농도로 표층수에서 검출되었으며 최대 검출 농도는 조사기간 중 매달 100ngl−1 이상이었다. Malathion, mevinphos, phorate, chlorfenvinphos도 비교적 높은 농도로 검출되었다. 많은 유기인계 농약들이 여름에 많이 사용되어지기 때문에 해양환경에서 겨울보다 여름에 더 빈번히 검출되었다. 해수 중 유기인계 농약의 농도는 만 입구에서 외만으로 갈수록 감소하여 이 농약들이 해양환경 중에서 분해, 희석되는 것으로 판단되었다. 아산만에서 측정된 diazinon 농도는 해양수질 환경기준인 20,000ngl−1 을 넘지 않았다. 표층수에서 검출된 malathion, parathion의 농도는 각각 해양수질 환경기준인 250,000ngl−1 과 60,000ngl−1 를 넘지 않았다. DDVP, phorate, stirofos, EPN, azinphos-methyl, IBP 는 다른 유기인계 농약보다 부유입자에 잘 흡착되는 것으로 나 타났다. 아산만에서 채취한 시료에서 계산된 유기인계 농약의 부유입자에 대한 흡착계수( Kd−particle )는 보고되어진 토양에의 흡착계수( Kd−soil )와 밀접한 관계가 있는 것으로 나타났다. Distribution characteristics of organophosphorous pesticides(OPs) in water and suspended particles were studied in Asan Bay, Korea, from June 2004 to October 2005. 28 organophosphorous pesticides could be detected in Asan Bay during this study. The most commonly and abundantly measured OPs in the surface waters were IBP (max= 6,343.7ngl−1 ). DDVP, diazionon, ethoprophos and methidathion were also observed at relatively high concentrations. Their maximum concentrations exceeded 100ngl−1 in almost every month. Malathion, mevinphos, ph orate and chlorfenvinphos were also detected at relatively high concentrations. Many OPs more frequently appeared in summer than in winter due to the intensive application of pesticides in summer months. The concentration of OPs generally decreased with increasing distance from the mouth of Asan Bay. This result implies progressive dilution of these pesticides in the marine environment. Measured concentrations of diazinon were well below 20,000ngl−1 which is a limit set by the seawater quality standard of Korea. The concentrations of malathion and parathion in the surface waters of Asan Bay did not exceed the seawater quality standard of Korea( 250,000and60,000ngl−1 respectively). OPs adsorbed on suspended particles were also studied. DDVP, phorate, stirofos, EPN, azinphos-methyl and IBP had higher adsorption capacity onto suspended particles than other pesticides. Calculated pesticide-particle adsorption coefficient( Kd−particle ) for samples collected in Asan Bay were closely related to the reported pesticides-soil adsorption coefficient ( Kd−soil ). -
