Abstract
A freshwater fish carp(Cyprinus carpio) was exposed to two organophosphorus insecticides in laboratory to investigate the potential of its bioconcentration. The results are summarized as follows: Bioconcentration factor of diazinon and fenitrothion after 24-hour exposure at 1 ppm concentration was 31 and 57, respectively, for the whole fish. The factor varied among different tissues of the fish in the decreasing order of viscera>rests>gills>muscle. When the fish was exposed to fenitrothion for 28 days at three different concentrations of 6, 30 and 150 ppb, bioconcentration factor in the whole fish ranged from 96 to 138, with a decreasing tendency at higher water concentration. The pesticide was continuously absorbed by the fish, but reaching an equilibrium at the tissue concentration of about 3.5 ppm.
잉어에 의한 두 가지 유기린계(有機燐系) 살충제의 생물농축(生物濃縮)을 추구(追求)하기 위하여 실험실 조건하에서 수행한 실험결과 는 다음과 같다. 1) Diazinon과 fenitrothion의 1 ppm농도에서 잉어에 의한 생물농축계수(生物濃縮係數)는 24시간후에 각각 31과 57이었다. 이 계수(係數)는 잉어의 부위(部位)에 따라 달리 나타났는 바 내장(內臟)>기타 부위>아가미>근육(筋肉)의 순서로 나타났다. 2) 잉어를 fenitrothion의 세가지 농도에 28일간 노출시킨 결과 생물농축계수(生物濃縮係數)는
