Abstract

This study was conducted to experiment the removal efficiency of 6 pesticides in fruits and vegetables using various washing solutions. As results, the average removal efficiencies of pesticides washed with tap-water were 68.3%, whereas those washed by ultrasonic cleaning for 2 and 5 minutes were 73.7% and 82.5%, respectively. Using different washing solutions with various additional materials such as 0.5% detergent, 5% vinegar, 5% salt and flour, the removal rates were 82.9%, 76.9%, 75.8% and 75.7%, respectively. With 0.5% detergent, pesticides were 20% more removed when washed by ultrasonic cleaning than tap-water washing; moreover, Chlorthalonil in cherry tomato showed the highest removal efficiency while EPN in grape washed with tap-water showed the lowest. The order of removal efficiencies of pesticides were Chlorthalonil (90.0%)>Procymidone (81.3%)>Chlorpyrifos (76.6 %)>Endosulfan (75.7%)>Fenitrothion (75.5%)>EPN (73.8%).

치커리, 청경채, 방울토마토, 포도 등 과 채류 4종에 Chlorpyrifos, Chlorothalonil, Endosulfan, EPN, Fenitrothion, Procymidone 등 농약 6종을 인위적으로 부착시켜 잔류농약 제거율을 조사한 결과, 수돗물 세척에서 전체 평균 제거율은 68.3%, 수돗물을 이용한 초음파 2분 및 5분간 세척에서 73.7, 82.5%로 나타났고, 4종의 첨가제액를 이용한 세척에서는 0.5% 세제액(82.9%)>5% 식초액(76.9%)>5% 소금물(75.8%)>5% 밀가루액(75.7%) 순으로 나타나 0.5% 세제액이 가장 높은 제거율을 보였으며, 나머지 3종류의 첨가제는 비슷한 제거율을 나타내었다. 첨가제액를 이용한 초음파 세척에서는 첨가제액 세척보다 $1{\sim}3%$ 정도 높게 나타났으며, 0.5% 세제액으로 5분간 초음파 세척시 89.3%로 수돗물 세척보다는 20%정도 높은 제거율을 보였다. 한편 전체 결과에서 최고 및 최저 제거율은 방울토마토중 Chlorthalonil 이 99.0%(0.5%세제 초음파 5분간 세척), 포도 중 EPN이 47.8%(물세척)로 나타났고, 농약별로는 Chlorthalonil(90.0%)>Procymidone(81.3%)>Chlorpyrifos(76.6%)>Endosulfan(75.7%)>Fenitrothion(75.5%)>EPN(73.8%) 순으로 높은 제거율을 보였다.
