Abstract
1999년 하계에 아산만과 겸기만 해역의 유기인계 잔류농약 분포를 조사하였다. 표층해수 중 IBP는 모든 해역에서 광범위하게 분포하였다. 아산만의 표층해수 중 IBP 농도 범위는 7월과 9월에 각각 10.3-1030.1(m=339.1), ND-319.1(m=74.8)ng/L였고 경기만 표층해수 중 IBP 농도는 7월과 9월에 각각 ND-76.2(m=29.1), ND-270.3(m=46.6)ng/L였다. Diazinon, DDVP, Ethoprophos와 Chlorpyrifos는 다소 낮은 농도를 보였지만 모든 해역에서 검출되었다. 다른 유기인계 농약(Disulfoton, Parathion Methyl, Fenchlorfos, Prothiofos, EDDP)은 일반적으로 검출한계 미만이었다. 퇴적물 중에서는 Chlorpyrifos가 다른 유기인계 농약보다 널리 분포하였다. 유기인계 농약의 시공간적 분포는 각 지역에 사용되어지는 농약의 사용량과 종류에 따라 달라진다고 보여진다. To study the distribution of organophosphorus pesticides which are extensively used for agriculture in Korea. Surface sea water samples were taken from 2 coastal areas during July and September of 1999 and sediment samples were collected from Kyeonggi bay in July of 1999. These samples were analyzed using a Gas Chromatography/Nitrogen Phosphorus Detector(GC/NPD). In coastal waters of the study areas IBP was commonly found the most compound. Traces of Diazinon, DDVP, Ethoprophos and Chlorpyrifos were also encountered. Concentration of the other major organophosphorus pesticides(Disulfoton, Parathion Methyl, Fenchlorfos, Prothiofos, EDDP) were generally be below the detection limit of the employed analytical method. In sediment of the study areas Chlorpyrifos was found the most compound. Temporal and geographical distribution of individual organophosphorus pesticides is likely to be affected by types of agricultural practices in the watershed.
