Assessing the antioxidant enzymes activity as biomarkers of oil pollution in mudskipper (Periophthalmus waltoni) from Bushehr coastal area waters (Persian Gulf)

Persian Gulf is known as an area with great amounts of oil reservoirs and due to this fact it has lots of harmful effects; so monitoring of this area is very important and it needs simple methods that reduce cost. Catalase (CAT) and glutathione reductase (GR) as antioxidant enzymatic biomarkers were assayed in liver of mudskipper Periophthalmus waltoni in 3 different stations in Bushehr coastal waters: Soltani Inlet, Shif Island and Ameri Port which showed significant differences (P<0.05) of enzyme activity in Soltani Inlet samples. Differentiation with sexes were not significant in three stations. 1-hydroxypyrene in bile of samples showed high and significant (P<0.05) amounts of oil pollution in Soltani Inlet in compare with two other stations. These three biomarkers were verified each other and have the potential of using in future studies.
