Summary

Researchers investigated the ecotoxicological effects of 3-methylphenanthrene, a marine oil spill contaminant, on Japanese spiky sea cucumber (Apostichopus japonicus), finding concentration- and time-dependent decreases in gastrula survival rate, increased bioaccumulation, and significant inhibition of CYP450 and p53 gene expression across all treatment groups.

In the Marine environment, 3-methylphenanthrene mainly comes from Marine oil spill accidents and the waste water discharge from the coastal petrochemical enterprises. In order to reveal the ecotoxicological effects of 3-methylphenanthrene pollutants on A. japonicus, it was exposed to different concentrations of the substance. The results showed, the survival rate of A. japonicus gastrula decreasing gradually with the extension of exposure time and the increase of exposure concentration; The bioaccumulation of 3-methylphenanthrene in A. japonicus increased significantly with the extension of exposure time and the increase of exposure concentration; Compared to the control group, the expression of CYP450 and p53 genes of A. japonicus was significantly inhibited in each treatment group. The above results provide the basic data for the evaluation of the biological toxicity of 3-methylphenanthrene towards A. japonicus.
