초록

황토유황합제는 우리나라에서 농작물 생산에 살균살충작용을 가지는 것으로 알려져 친환경유기농자재로 널리 사용되고 있으나, 알칼리성이 강하여 작물에 약해를 보일 뿐 아니라 농업자의 피부 및 안점막에 자극성이 있는 것으로 보고되고 있어 제품으로서의 안전성에 대한 우려가 높다. 본 연구에서는 작물의 약해를 저감하기 위해 pH를 조정하여 제조한 황토유황합제 3종(pH 9, pH 10, pH 11)의 인축 급성독성시험을 시행하여 인체 안전성을 확인함으로써 친환경유기농자재 개발시 최적의 제품 선정에 기초자료로 활용하고자 하였다. 랫드를 이용한 급성경구독성시험 결과 황토유황합제는 $LD_{50}$이 2,000 mg/kg b.w. 이상이었으며, 급성경피독성시험 결과 또한 모두 4,000 mg/kg b.w. 이상인 저자극성으로 분류되었다. 피부 및 안점막자극성 시험 결과에서도 모두 저자극성으로 구분되었으며 pH 9~11 범위에서 제품간 독성분류의 차이는 나타나지 않았다.

Abstract

Loess-sulfur complex has been widely used as an environmental friendly organic materials for insecticides and fungicides in crop cultivation. However, there are high concerns about skin and eye irritation for farm workers due to the high alkaline properties of loess-sulfur complex. The acute toxicity evaluation was conducted with three samples of loess-sulfur complex in different pH (pH 9, 10, 11) in order to supply the evidentiary data for selecting the optimal product among the test materials. The results of acute oral toxicity using rats showed $LD_{50}$ of over 2,000 mg/kg b.w. for all three samples of loess-sulfur complex. The calculated acute dermal $LD_{50}$ of all tested materials was over 4,000 mg/kg b.w.. The Skin and eye irritation indicated that all tested materials have no irritation. Consequently, it was suggested that loess-sulfur complex be low in acute toxicity at all different pH values (pH 9~11).
