Abstract
In the laboratory experiment, concentration and rate of runoff of 7 pesticides were measured under the simulated rainfall. Total runoff rate of metolachlor, alachlor, chlorothalonil, chlorpyrifos, EPN, phorate and captafol were 57.0, 14.2, 13.2, 7.9, 7.2, 7.1 and 2.8%, respectively, and the average runoff concentrations were 940, 399, 55, 7.0, 9.3, 151 and 7.0 ppb, respectively. Significant relationship was observed between the runoff rate and water solubility in the laboratory experiment(r=0.923). Even though not very high, relatively significant results were obtained in other experimental conditions. Based on the results, runoff rate prediction
강우에 의한 농약의 토양표면 유출특성을 알아보고자 인공강우(20 mm/hr)에 의한 실내 유출실험을 7개 농약을 대상으로 수행한 결과, 유출율은 metolachor 57.0%, alachlor 14.2%, chlorothalonil 13.2%, chlorpyrifos 7.9%, EPN 7.2%, phorate 7.1%, captafol 2.8%였고, 평균 유출농도는 각각 940, 399, 55, 7.0, 9.3, 151, 7.0 ppb였다. 유출율과 농약의 물리화학적 특성(수용성, 분배계수, 토양흡착계수)과의 상관관계를 보면 실내유출실험에서 수용성과의 상관성이 높았으며(r=0.923), 그 이외의 실험조건에서도 수용성 보다 높지는 않았지만 상관성이 유사하였다. 이 결과를 바탕으로 실내 실험결과를 이용한 포장에서의 유출을 예측가능성을 확인하고자 유출을 예측식
