Abstract

Toxicity test for biodiesel (BD), biodiesel-derived neopentyl polyol ester (NPE) lubricant oil base, lubricant oil for diesel engine (LODE) and petroleum diesel (PD) was carried out using microalgae, Chlorella vulgaris. According to the method of OECD 201, the $EC_{50}$ values of BD and NPE were estimated as 84 and 69 mg/L, respectively, which indicates that these compounds are classified as slightly toxic compounds. The $EC_{50}$ values of LODE and PD were measured as 42 and 24 mg/mL, respectively, showing that these compounds are considered as moderately toxic compounds.

바이오디젤과 바이오디젤을 기반으로 생산된 neopentyl polyol ester (NPE)계 윤활유 베이스, 디젤유 윤활유와 석유디젤을 분석대상으로 하여 독성을 평가하였다 조류를 이용하여 수용액 상에서 화학물질의 독성시험을 조사하는 OECD 201에 근거하여 Chlorella vulgaris를 96시간 동안 배양하면서 독성시험 분석한 결과, 바이오디젤과 NPE계 윤활유 베이스의 반수저해농도 $(EC_{50})$ 값은 각각 84와 69mg/L로서 두 물질이 독성 이 적은 경독성 (slightly toxic)물질인 것으로 판명되었다. 디젤유 윤활유와 석유디젤의 경우 반수저해농도 $(EC_{50})$ 값이 각각 42와 24 mg/L로서 중등독성 (moderately toxic) 물질로 판정 되었다.
