Abstract:The relationships between total mercury (Hg) concentration and stable nitrogen isotope ratio (δ 15 N) were evaluated in Mullus barbatus barbatus and M. surmuletus from the Mediterranean Sea and M. barbatus ponticus from the Black Sea. Mercury concentration in fish muscle was six times higher in the two Mediterranean species than in the Black Sea one for similar sized animals. A positive correlation between Hg concentration and δ 15 N occurred in all species. Increase in Hg concentration with δ 15 N was high and similar in the two Mediterranean fishes and much lower in the Black Sea species. Since this was neither related to trophic level difference between species nor to methylmercury (MeHg) concentration differences between the north-western Mediterranean and the Black Sea waters, we suggested that the higher primary production of the Black Sea induced a dilution of MeHg concentration at the base of the food webs.

The aim of this study was to monitor the heavy metal contents and fecal pollution in Tapes decussatus (carpet shell clam) from Izmir Bay (Eastern Aegean). Bivalve mollusks were sampled on January, March, July, and October 2007 in the Izmir Bay. Izmir Bay is one of the great natural bays of the Mediterranean. Concentrations of heavy metals were determined in the clams from the different seasons. Fecal coliform densities were determined to evaluate the degree of water pollution and clams' microbiological accumulation of the classical microbial pollution indicators. The concentration of heavy metals in T. decussatus from Izmir Bay were Hg 0.044-0.13; Cd 0.026-0.24; Pb 0.38-1.2; Cr 2.3-3.7; Cu 6.4-8.4; Zn 56.0-81.8, and Ni 8.1-9.6 microg/g (dry weight). The maximum values were generally obtained in July and March except Ni. This study found that the levels of heavy metals except Cr in T. decussatus were below Spanish and European Communities legislations for shellfish as food. Microbial pollution indicators (heterotrophic bacteria and fecal coliform) were measured in T. decussatus. Maximum heterotrophic bacteria and fecal coliforms were recorded in the winter while the lowest were detected in summer.

“…It is roughly L-shaped, and it is connected with the Aegean Sea. Izmir Bay is divided into inner, middle and outer bays due to topographical and hydrographical characteristics (Küçüksezgin et al 2002;Sunlu 2004). Generally, the sections of the bay are distinguished from one another by their different depth characteristics.…”

“…For sediments, there is a limited number of studies realised in Izmir Bay; although there are many investigations presently available on trace metals, some natural radionuclides and gross radioactivity concentrations, no data have appeared in literature for 210 Po and 210 Pb contents in the sediments of Izmir Bay (Uysal and Tuncer 1982;Demirkurt et al 1990;Küçüksezgin and Balcı 1994;Yılmaz 1995;Sunlu et al 1998;Küçüksezgin et al 2002;Sunlu 2004;Bergin et al 2006). Thus, measurements of activity concentrations of 210 Po and 210 Pb in sediments of Izmir Bay will be valuable for future research activities in this area.…”

Bottom sediments reflect in general the relative contamination of a sea area. Therefore, a great deal of monitoring work has been dedicated to the analysis of bottom sediments. Izmir Bay is a very important pollution centre in Turkish Aegean coast region due to a densely populated community, industrial complex and maritime transportation, and there are many streams flowing into the bay that pass through a number of industrial and agricultural areas. It had received the majority of domestic and industrial wastewaters until the wastewater treatment plant was constructed. It is well known that sediments play an important role as reservoirs of a fraction of the pollution in aquatic systems. Therefore, sediment samples were collected monthly from three stations which are located in the inner part of the bay during the period January to December 2003. Temporal variations and seasonal changes on their (210)Po and (210)Pb contents were examined, and the activity concentrations of (210)Po and (210)Pb were found to vary from 43+/-6 to 132+/-12 and 27+/-5 to 91+/-9 Bq kg(-1) dry wt, respectively. The highest values of those natural radionuclides were measured at Karşiyaka Station because of the current systems of the bay. Seasonally, the (210)Pb levels were found to increase during the winter time for all the stations.
