Abstract

Toxicity test for biodiesel (BD), biodiesel-derived neopentyl polyol ester (NPE) lubricant oil base, lubricant oil for diesel engine oil (LODE) and petroleum diesel (PD) was carried out using earthworm, Eisenia fefida. According to the method by OECD 207, the $LC_{50}$ values of BD and NPE were estimated as 2,450 and 1,528 mg/kg, respectively, which indicate that these compounds are classified as slightly toxic compounds. The $LC_{50}$ values of LODE and PD were estimated as 500 and 603mg/kg, respectively, showing that theses compounds are evaluated as moderately toxic compounds.

바이오디젤과 바이오디젤을 기반으로 생산된 neopentyl polyol ester (NPE)계 윤활유 베이스, 디젤유 윤활유와 석유디젤을 분석대상으로 하여 지렁이 (Eisenia fetida)를 이용한 독성 시험을 수행하였다. OECD 207규격에 근거하여 독성을 분석한 결과 바이오디젤과 NPE계 윤활유 베이스의 반수치사농도 $(LC_{50})$ 값은 각각 2,450과 1,528 mg/kg dry weight of soil로서 두 물질은 독성 이 적은 경독성 (slightly toxic) 물질인 것으로 판명되었다. 디젤유 윤활유와 석유디젤의 경우 반수치사농도 $(LC_{50})$ 값이 각각 500과 603 mg/kg로서 중등독성 (moderately toxic) 물질로 판정되었다.
