우리나라 주요(主要) 하천수(河川水)에 대(對)한 농약잔유실태(農藥殘留實態)를 파악(把握)하여 농약안전사용(農藥安全使用)의 기초자료(基礎資料)로 활용(活用)코자 5대강(大江) 본류(本流)를 중심(中心)으로 주요(主要) 지류유입지점(支流流入地點)을 강별(江別)로 5개소(個所)를 선정(選定), 갈수기(渴水期)(4월(月))와 성수기(盛水期)(8월)에 동일(同一) 지점(地點)에서 시과(試科)를 채취(採取)하여 하천수중(河川水中) 농약잔유량(農藥殘留量)을 조사(調査)하였다. 조사대상지역(調査對象地域)이나 조사시기(調査時期)와는 무관(無關)하게 하천수중농약잔유량(河川水中農藥殘留量)은 극미량(極微量)으로 검출(檢出)되었다. 대체(大體)로 성수기(盛水期)가 갈수기(渴水期)에 비(比)해 다소(多少) 높은 수준(水準)으로 검출(檢出)되었는데, IBP와 diazinon의 경우는 그러한 현상(現象)이 더욱 현저하였다. 유기인계농약(有機燐系農藥)은 IBP와 diazinon만이 검출(檢出)되었으며, fenthion, fenitrothion, chlorpyriphos, chlorpyriphos-methyl, chlorfenvinphos, phenthoate, 및 edifenphos는 어느 시료(試料)에서도 검출(檢出)되지 않았다. IBP와 diazinon의 조사최고치(調査最高値)는 각각(各各) 1.53과 0.39ppb이었다. 유기염소농약(有機鹽素農藥)은 조사시기(調査時期)에 따른 차리(差異)가 거의 없었다. Aldrin은 어느 시료(試料)에서도 검출(檢出)되지 않았으며, dieldrin과 p.p`-DDT는 극(極)히 일부(一部) 시료(試料)에서만 극미량(極微量)으로 검출(檢出)된 반면(反面), BHC와 heptachlor및 ${\alpha}-endosulfan$의 검출빈도(檢出頻度)는 다소(多少) 높은 편(便)이나 그들의 잔류수준(殘留水準)은 매우 낮았다.

To obtain basic information for the safe use of pesticides, the aquatic environment of 5 major rivers was surveyed in April and August 1982 for organochlorine and organophosphorus pesticide residues. Regardless of sampling times and sites, pesticide residue levels were very low. Of the organophosphorus pesticides surveyed, only IBP and diazinon were detected in water samples while fenthion, fenitrothion, chlorpyriphos, chlorpyriphos-methyl, chlorfenvinphos, phenthoate, and edifenphos were not detected in any water samples. Residue levels and detection frequencies of IBP or diazinon were much higher in water samples collected in August than those collected in April. Detection frequencies of organochlorine pesticides, on the other hand, were high, but their actual residue levels were very low. BHC was detected nearly in all water samples while aldrin was not found in any samples. Detection frequencies of heptachlor, endosulfan, and o.p`-DDT were considerably high but dieldrin and p.p`-DDT were detected in a few water samples and their residue levels were also very low.
