不同发育期诸氏鲻虾虎鱼对钻井液的敏感性比较
Comparison of the sensitivity of Mugilogobius chulae at different developmental stages to drilling fluid
摘要
Abstract
Objective To sreen suitable developmental stage of Mugilogobius chulae for acute toxicity test. Methods The prelarva, middle larva, postlarva, juvenile, young, and adult M. Chulae were exposed to water-based drilling fluid in five concentrations and the acute toxicity of drilling fluid to M. Chulae at different development stagesa was compared with that in the control group. Results The 48 h median lethal concentration ( LC50) of the drilling fluid to M. chulae prelarva was 157 mg/L and to the middle larva was higher than 500 mg/L. The 96 h LC30 to the middle larva was 79 mg/L and to the postlarva was 625 mg/L. The 96 h LC50 of the drilling fluid to juvenile, young and adult fish was obviously exceeded 500 mg/L. That of the drilling fluid to Anemia nauplius was 105 mg/L. The sequence of sensitivity to drilling fluid of M. Chulae at different developmental stages was prelarva ＞ middle larva ＞ postlarva ＞ juvenile, young and adult. Concolusion Prelarva of Mugilogobius chulae is suitable as a laboratory organism for acute toxicity evaluation of marine pollutants.关键词
