dc.description.abstractThe Black Sea has been increasingly threatened by pollutants over the past decades due to uncontrolled shipping, accidental crude oil spills, and discharge of industrial and domestic wastes from coastal settlements. There are few studies concerning biomarker responses to pollutants in the Black Sea. In this study, CYP1A-associated 7-ethoxyresorufin O-deethylase (EROD) activity (induced by polycyclic aromatic hydrocarbons, polychlorinated biphenyls and dioxins) the phase II detoxifying enzyme glutathione S-transferase (GST) and the antioxidant defense enzyme catalase (CAT) were used as biomarkers. Fish were collected in August 2005 by net, from five sites representing a pollution gradient in the West Black Sea Region of Turkey. Mullet collected from the Zonguldak Harbor, a highly urbanized and industrial city in the West Black Sea Region, had 7-fold higher EROD activities than Kefken, a less contaminated site. The mullet samples collected from Sakarya River Mouth, Melen Stream Mouth and Guluc Stream Mouth displayed between 2 and 3 fold higher EROD activities compared to Kefken. GST activities of the samples from the four sites with elevated EROD activities ranged between 2- and 3-fold higher than in fish from Kefken. Likewise CAT activities of samples from these four sites were 4-fold higher than Kefken. In this study, the elevated biomarker responses indicate that Zonguldak Harbour, Sakarya River, Melen and Guluc Stream have tendency to create a local pollution in the Black Sea. Additionally, the pollution status of Zonguldak Harbour was the highest between the sampling sites with regard to toxic organic pollutants.
