Effect of water-accommodated fractions of No.0 diesel oil on embryos and larvae development of sea urchin，Hemicentrotus pulcherrimus

摘要：

The paper aims at present the acute toxic effect of water-accommodated fraction（WAFs） of No.0 diesel oil on embryos and larvae development of sea urchin, Hemicentrotus pulcherrimus by adopting embryonic development technology. The experiment was carried out with six concentrations. The results indicate that the water-accommodated fractions have evident toxic effect on two -arm and four -arm larvae. Compared with the control group, the larvae in the oil groups showed shorter body lengths and higher deformity and mortality rate by the increasing concentrations. The 48h, 72h EC50 is 3.39、1.87mg/l respectively.
