Aim of this study was to determine the extent of pollution in the West Black Sea Coast of Turkey by measuring CYP1A associated EROD activity, phase II enzyme, glutathione S-transferase and antioxidant enzymes, catalase and glutathione reductase activities and immunochemical detection of CYP1A protein level in the liver of mullet. The fish samples were caught from six locations having a varying degree of pollution in the West Black Sea Region of Turkey in August 2005, 2006 and 2007. Mullets caught from Zonguldak Harbour, Eregli Harbour and Guluc Stream's Mouth displayed 6-9-fold higher EROD, 2-4-fold higher glutathione S-transferase and 2-3-fold higher catalase activities than the reference site, Amasra. Total polyaromatic hydrocarbon levels in mullets caught from these locations were also significantly higher (2-4-fold) than Amasra. The results Of this Study indicate that Zonguldak Harbour, Eregli Harbour and Guluc Stream are highly Polluted by polycyclic aromatic hydrocarbons and related contaminants.

Inhibitory effects of divalent metal ions on liver microsomal 7-ethoxyresorufin O-deethylase (EROD) activity of leaping mullet Bozcaarmutlu, A; Arinc, E (Elsevier BV, 2004-08-01) The purpose of the present study was to elucidate in vitro effects of Hg2+, Zn2+, Ni2+ and Cd2+ on cytochrome P4501Al (CYP1A1) dependent EROD activities in leaping mullet liver microsomes. Fish captured from the most polluted part of Izmir Bay, had highly elevated EROD activities, and induced CYP1A1 protein levels as determined by Western blotting. Although all of the metal ions caused inhibition of the initial velocity of the reaction, Hg2+ and Cd2+ exhibited much higher inhibitory effect at lower concentr...
Assessment of temporal variation and sources of PCBs in the sediments of Mediterranean Sea, Mersin Bay, Turkey Gedik, Kadir; İmamoğlu, İpek (Elsevier BV, 2011-01-01) Information on temporal distribution of polychlorinated biphenyls (PCBs) in the coastal sediments of Mediterranean Sea, Mersin was compiled using data published between 1980 and 2009, and the present study. The first congener specific PCB results from the region yield concentration levels of Sigma(41) PCBs in sediments ranging from 0.61 to 1.04 ng g(-1). Sediment profiles show penta-, hexa- and hepta-chlorobiphenyls, specifically, #149 and 153 as the most abundant congeners in all samples. Comparison of tot...
Trace metal levels in fish and crustacea from Northeastern Mediterranean coastal waters Balkas, Turgut I; Tuğrul, Süleyman; Salihoǧlu, Ǐlkay (Elsevier BV, 1982-06-01) Some fish and crustacea caught near the northeastern Mediterranean coast of Turkey between 1977 and 1980 have been analysed by the AAS technique for their H Hg, Cd, Pb, Zn, Cu, Fe, Ni, Cr and Mn contents. In the crustacea Portunus pelagicus (crab) and Penaeus keratherus (shrimp), the two essential elements Zn and Cu, showed a linear correlation. Among the bony fish, Upeneus moluccensis (gold band goat fish), a member of the Mullidae family, and Portunus pelagicus showed a much greater tendency to accumulate...
Parameterization of iron and manganese cycling in the Black Sea suboxic and anoxic environment Konovalov, S; Samodurov, A; Oguz, T; Ivanov, L (Elsevier BV, 2004-12-01) New and published data on the distribution and speciation of manganese and iron in seawater are analyzed to identify and parameterize major biogeochemical processes of their cycling within the suboxic (similar to15.6less than or equal tosigma(t)less than or equal tosimilar to16.2) and anoxic layers (sigma(t)less than or equal tosimilar to16.2) of the Black Sea. A steady-state transport-reaction model is applied to reveal layering and parameterize kinetics of redox and dissolution/precipitation processes. Pr...
The inhibitory effects of lindane in batch and upflow anaerobic sludge blanket reactors Bayramoğlu, Tuba Hande; Demirer, Göksel Niyazi (Elsevier BV, 2003-01-01) In this study, the inhibitory effects of lindane (LIN) on originally unacclimated mixed anaerobic cultures were investigated by anaerobic toxicity assay (ATA) experiments. ATA experiments revealed that 10 mg/l LIN exerted inhibitory effects on anaerobic cultures, which was recoverable. Continuous reactor experiments conducted to determine the inhibitory effects of LIN and the maximum LIN loading rate achievable in two-stage upflow anaerobic sludge blanket (UASB) reactors indicated that anaerobic granular cu...
