  • This experiment was conducted to elucidate the effects of fruit bagging on the amounts of pesticide residues on/in pears with two pesticides, chlorpyrifos 25% WP, and penconazole 5% WP, and two pear cultivars, Niitaka and Hwangeum-bae. Residues of chlorpyrifos and penconazole in bagged pears were only $0.4{\sim}27%$ of those in non-bagged one. Residues of both pesticides in bagged and non-bagged pears were steeply reduced in the field but slowly reduced during storage. Residues of chlorpyrifos were more in the peel than in the flesh, while penconazole in bagged pear was evenly distributed in the peel and flesh. Chlorpyrifos was evenly distributed in outer bag and inner bag irrespective of bag materials, while most of penconazole was found in outer bag rather than in inner bag. To produce safer pear from pesticide residues, removal of bag before storage is recommended.

  • 농약을 매년 사용하게 되면 토양 중의 농약잔류량은 계속 증가할 것으로 생각되기 쉬우나, 실제로 토양중 농약잔류량은 지수 함수적으로 감소하기 때문에 매년 계속해서 사용하더라도 몇 년 후에는 평형상태에 도달하여 그 이상은 증가하지 않기 때문이다.

  • This study estimated the correlation between surface area/weight ratios and pesticide residues in two varieties of tomato, mini tomato and tomato. The ratios of surface area/weight of mini tomato and tomato were $2.15cm^2g^{-1}$ and $1.00cm^2g^{-1}$ respectively. Pesticide residues were measured with four kinds of pesticide, chlorothalonil WP, chlorothalonil SC, oxadixyl WP, thiophanate-methyl WP. Ie residue amount of mini tomato was $1.4\sim2.4$ times higher than those in tomato regardless of the application date and frequency. The ratios of surface area/weight on tomato varieties played a key role for determining pesticide residue.

  • 최근, 수입농산물의 증가에 따라, 일본내에서는 사용되지 않는 농약과 일본에는 없는 사용형태인 수확후 사용되는 농약(post-harvest농약)에 특별히 높은 관심이 더해지게 되었다. 특히 수확후에 사용되는 post-harvest 농약은, 잔류량이 많아 사람의 건강을 해칠 위험이 있는 화학물질로 문제되는 일이 많은데 그 원인의 하나로서, 농산물중 농약의 잔류실태가 명확치 않은 것을 들 수 있다. 농약의 유무는 외견상으로는 전혀 판단할 수 없다. 일반적으로 농약을 사용하여 재배한 작물에도, 농약이 잔류해 있다고는 한정짓지 않는다. 전답에서 사용된 농약은, 환경중에서 또는 식물체내에서 분해되어 소비자에게 판매되게 되기 때문이다. 따라서 농약의 잔류는 검사를 하고서야 판명된다. 시판 농산물에는 어떠한 농약이 어느정도 잔류해 있는 것인가? 여기에서는 1991년도 검사한 결과를 중심으로 농약의 잔류실태에 대해서 서술하고자 한다.

  • 1. In the vegetable crops, only MEP and Malathion showed a litte higher positive rate than other pesticides in general. On the other hand, parathion and captan were not detectable at all. 2. In the fruits, pesticides, MEP, PAP and Parathion had a little high positive rate, and Diazinon, and captan were not detectable at all. 3. However, the detected values of the pesticides in the vegetables and fruits were far below from korean tolerances and internationally recommended limits and tolerances, showing only $\frac{1}{3}{\sim}\frac{1}{66}$ and $\frac{1}{8}{\sim}\frac{1}{500}$ of Korean tolerance in vegetables and fruits, respectively.

  • “시중 채소류 잔류농약 범벅”신문이나 TV에 자주 등장하는 낯익은(?) 제목이다. 그리고는“조사대상 농산물 중 OO% 허용기준치초과. 최고 OO배에 달해, 사용이 금지된 농약도 나와, 잔류농약은 식품과 함께 일생동안 섭취되기 때문에 만성중독 가능성을 배제할 수 없다”같은 내용이 그 뒤를 잇는다. “일생동안 섭취”문제는 이미 지난 10월호에서“1일 섭취허용량” 을 다루었기 때문에 이해가 된다. 하지만 식생활을 하면서 농약 섭취가 1일섭취허용량 이하로 되도록 하려면 식품에 농약이 어느 정도까지 있어야 안전한가?”가 의문이다. 그 허용기준이 농산물(식품) 중“농약잔류허용기준”이다. 이는 보통“기준치, 허용치, 허용기준, 허용기준치, 잔류허용기준”등으로 불리우고 있다.

  • The study was carried out to investigate the pesticide residual characteristics in peaches, pear and grape. Pesticide residue patterns were remarkably different because of major factors affecting the pesticide residue patterns such as ratios of surface to weight, surface matrices, cultivations, sizes, increase rate of weight, and varieties of fruits, etc.. Pesticide residue levels in grape appeared higher than those in peaches and pear, because the pesticide solution sprayed was infiltrated and accumulated between grape granules. The matrices composing of fruit surface and the ratios of surface area to weight on fruits seemed to playa key role for determining the pesticide residual characteristics in fruits.
