남해안일대(南海岸一帶)에서 1974년 9월에 수집한 패류(貝類), 해조류(海藻類), 저질토(底質土) 및 수질(水質)중의 유기염소계(有機鹽素系) 농약잔류량을 분석한 결과는 다음과 같다. 1) 패류(貝類)중 잔류농약은 산지(産地) 및 종류에 따라 달리 나타났는 바 산지(産地)별로는 충무>여수>목포의 순으로, 패류(貝類)별로는 소라>바지락>홍합>백합>꼬막의 순으로, 농약별로는 aldrin> ${alpha}-BHC$ > heptachlor > ${gamma}-BHC$ > dieldrin > heptachlor epoxide > endrin의 순으로 $0-49;{mu}g/kg$ (육질(肉質) 생체중(生體重))의 범위에 존재하였다. 2) 완도산(莞島産) 해조류(海藻類)중 잔류농약은 미역>파래>김>의 순으로 그리고 ${alpha}-BHC$ > ${gamma}-BHC$ > aldrin > dieldrin > heptachlor > heptachlor epoxide > endrin의 순으로 $0-60;{mu}g/kg$(건물중(乾物重))의 범위에 존재하였다. 3) 수질(水質) 및 저질토(底質土)중의 잔류농약은 지역별로는 영산강> 낙동강>섬진강>충무양식장의 순으로 수질(水質)에서는 ${alpha}-BHC$ > ${gamma}-BHC$ > aldrin >heptachlor >dieldrin > heptachlor epoxide > endrin의 순으로 $0-180;{mu}g/kl$의 범위에 존재하였으며 저질토(底質土)에서는 ${alpha}-BHC$ > ${gamma}-BHC$ > aldrin > dieldrin > heptachlor > heptachlor epoxide > endrin의 순으로 $0.7-18;{mu}g/kg$(건물중(乾物重))의 범위에 존재하였다. 특히 영산강 및 낙동강 하류(下流)의 수질(水質)중 BHC함량(含量)은 미국에서의 환경기준치(環境基準値)를 훨신 상회(上廻)하였다.
The appearance of organochlorine pesticide residues in shellfish, seaweed, mud and water samples collected from south coast of Korean peninsula in September 1974 was surveyed to obtain the following results. 1) The residues in shellfish samples were found to be in the orders of Choongmoo > Yeosoo > Busan > Mokpo area, top-shell >short-necked clam > mussel > hard clam > red-shell, aldrin > ${alpha}-BHC$ > heptachlor> ${gamma}-BHC$ > dieldrin > heptachlor epoxide > endrin and in the range of $0-49;{mu}g/kg$ edible fresh muscle. 2) The residues in seaweed samples from Wando area were found to be in the orders of tangle > green laver > laver, ${alpha}-BHC$ > ${gamma}-BHC$ > aldrin > dieldrin > heptachlor > heptachlor epoxide > endrin and in the range of $0-60;{mu}g/kg$ dry matter. 3) The residues in water samples were found to be in the orders of Yeongsan River > Nakdong River > Seomjin River > Choongmoo shellfish farm, ${alpha}-BHC$ > ${gamma}-BHC$ > aldrin > heptachlor > dieldrin > heptachlor epoxide > endrin and in the range of $0-180;{mu}g/kl$ while those in mud samples were in the order of ${alpha}-BHC$ > ${gamma}-BHC$> aldrin > dieldrin > heptachlor > heptachlor epoxide > endrin and in the range of $0.7-18;{mu}g/kg$ dry matter. It should be noted that BHC contents of water samples from Yeongsan and Nakdong rivers were far above the recommended environmental levels in USA.
