Evaluation of glutathione S-transferase activity as a biomarker of PAH pollution in mudskipper, Boleophthalmus dussumieri, Persian Gulf.

As an attempt to study on the biomarkers types to assess the specification of the pollutants and health status of marine ecosystems, sediments and biota (i.e., Boleophthalmus dussumieri) were collected from the Persian Gulf. The liver glutathione S-transferase (GST) activity in mudskipper was higher as compared with that in blood which could be illustrated by high metabolic rate in this organ, its key role in the metabolism of PAHs detoxification and specificity of enzymes composition. The results suggest that the liver GST activity in B. dussumieri was PAH inducible and could be extended as a biomarker of PAH pollution.
