유기염소계 잔류농약이 제주도 연안 해양환경에 미치는 영향
오윤근,김정호 ( Youn Keun Oh,Jung Ho Kim ) 한국물환경학회 1997 한국물환경학회지 Vol.13 No.3
To obtain the effects of residual organochlorine pesticides in the coastal environment on the Cheju Island, the ocean environment of Cheju city and Wimi was surveyed in May, August and October 1996. The qualification defection concentration of captan, chlorothalonil and dicofol of organochlorine pesticides in the water were 0.009ng/㎖, 0.005ng/㎖ and 0.023ng/㎖ by GC-ECD, respectively. The qualification defection concentration of captan, chlorothalonil and dicofol of organochlorine pesticides in the plant and animal were 0.018ng/g, 0.010ng/g and 0.046ng/g by GC-ECD, respectively. Captan, chlorothalonil and dicofol of organochlorine pesticides used in the farm were not detected in any water, sediment, seaweed cava(Ecklonia Cava), Agar(Gelidium amansii), turban sell(Batillus cornutus) and sea urchin(Anthocidaris Crassispina). The coastal environment in the cheju island was not effected the captan, chlorothalonil and dicofol of organochlorine pesticides used in the farm on cheju island

To study the residue of organophosphorus pesticides in the ocean environment on the Cheju island, EPN[O-ethyl-O-4-nitrophenyl phenylphosphonothioate] and monocrotophos [Dimethyl-1-methyl-2-methy] carbamoylvinylphosphate] of organophosphorus pesticides are surveyed on coastal environment of Cheju city and Wimi in May and October 1996. The qualified limit detection of EPN and monocrotophos are 0.005ng/mL and 0.006ng/mL., in the water by GC-FPD, respectively. The qualified limit detection of EPN and monocrotophos are 0.010ng/g and 0.012ng/g in the solid such as sediment and sea organism by GC-FPD, respectively. EPN and monocrotophos are not detected in seawater and sediment. Moreover EPN and monocrotophos are neither detected in seaweed cava (Ecklonia cava), Agar (Gelidium amansii), turban sell(Batillus cornutus) and sea urchin(Anthocidaris Crassispina). EPN, monocrotophos used in the farm on the Cheju island are not residued in the coastal environment in the Cheju island.

제주도 연안의 수산물 생산력 향상을 위해서는 연안 해양환경 보전이 무엇보다 중요하다. 특히 골프장의 농약 오염원이 연안환경과 수산생물에 미치는 영향을 규명할 필요가 있다. 따라서 제주도의 농업 오염물질 중 유기인계 농약에 의한 연안해역의 오염을 규명하고자, 1997년 7월과 8월에 남제주도에 위치한 중문골프장에 인접한 색달동과 대포동 근해 해양환경시료에서 monocrotophos와 EPN 유기인계 농약 잔류를 조사하였다. GC-FPD에 의한 monocrotophos와 EPN의 시료중 최소 검출농도는 동ㆍ식물의 고체시료에서는 0.024ng/g, 0.020ng/g이었다. 또한 해수에서는 각각 0.012ng/mL, 0.010ng/mL이었다. 식물시료인 우뭇가사리와 미역, 동물시료인 소라와 성게에 대한 유기인계 농약의 잔류량 조사 결과 모든 시료에서 monocrotophos와 EPN이 검출되지 않았다. monocrotophos와 EPN은 색달동과 대포동에서의 해수와 저니토에서도 검출되지 않았으며, 이러한 결과는 7월, 8월에서도 동일하였다. 따라서 남제주도 중문골프장 근해 해양 환경 중에서는 monocrotophos와 EPN의 유기인계 농약오염은 없는 것으로 나타났다. To investigate the residue of organophosphorus pesticides such as Monocrotophos[Dimethyl-l -methyl-2-methyl carbamoylvinylphosphate] and EPN[O-ethyl-O-4-nitnophenyl phenylphosphonothioate] in the coatal environmen of Cheju island, samples of sea organism, water and sediment were collected at the Sackdaldong and Daepodong near the Jungmoon golf course in July and Aug. 1997. The qualified detection limit of monocrotophos and EPN by GC-FPD were 0.024 ng/g and 0.020 ng/g in the sea organism, respectively. Neither Monocrotophos nor EPN was detected in seaweed cava(Ecklonia cava), Agar(Gelidium amansii), turban sell (Batillus cornutus) and sea urchin (Anthocidaris Crassispina). They were not detected in seawater and sediment either. These results showed that the coastal area near the Jungmoon golf course in the Cheju island was not polluted by the organophosphorus pesticides such as Monoc개tophos and EPN.

The adsorption and leaching of organophosphorus pesticides (phenthoate, diazinon, methidathion) were investigated in Namwon soil(black volcanic soil), Aewol soil(very dark brown volcanic soil) and Mureung soil(dark brown nonvolcanic soil) sampled in Cheju Island. The Freundlich constant, K value, was 52.4, 31.3 and 27.7 for phenthoate, diazinon and methidathion in Namwon soil, respectively and decreased in the order of phenthoate, diazinon and methidathion among the pesticides. The K value of phenthoate was 52.4, 15.9 and 5.9 for Namwon, Aewol and Mureung soil, respectively and was the highest for Namwon soil with very high organic matter content and cation exchange capacity(CEC). The Freundlich constant, 1/n, showed a high correlation with organic matter content, i.e., its value was less than unity for organic matter rich soil(Namwon soil) and greater than unity for organic matter poor soil(Mureung soil). Total recoveries of pesticides in soil and leachate with leaching in soil column, were in the range of about 74∼86%. The leaching of pesticides was less for phenthate with high K values, and more for methidathion with low K values among the pesticides. It was slower for Namwon soil with high K values, and faster for Mureung soil with low K values among the soils.
