Abstract

Although the removal efficiency of residual pesticides using tap water were ranged from -1.25 to $13.27\%$, the removal efficiencies of residual pesticides using both powder CaO and liquid CaO were $5.16\~l7.61,\;8.7\~41.59\%$, respectively. And those results showed much higher residual effect of the CaO washing than tap water washing. Natural CaO made by burning of scallop-shell considered to be a good reducing agent for pesticides. Furthermore, liquid CaO showed much higher removal efficiency than powder CaO. However, powder CaO also can be used as a good natural eliminator of pesticides in Mini-Tomato.

대표적 8개 유기인계 농약에 대한 tap water 세척의 제거효과인 $-1.25\~13.27\%$에 비해 powder CaO와 liquid CaO 세척은 각각 $5.16\~17.61,\;8.7\~41.59\%$로 매우 높은 농약제거 효과를 보였다. 조개껍질을 연소시켜 얻은 천연 CaO는 잔류농약 세척제로 사용하기에 적합하다고 사료되며,특히 액체가 가루에 비해 농약제거제로 더욱 효과적인 것으로 나타났다. 그러나 가루제품 역시 tap water로 세척 한 것에 비해서는 다소 높은 제거율을 보여 세척제로서의 사용이 가능한 것으로 판단된다. 이에 CaO등을 활용한 천연물 세척제가 조속히 실용화되어 국민의 안전한 식탁을 지키는데 활용되어야 할 것이다.
