    Bioaccumulation of some heavy metals in different tissues of Dicentrarchus labrax L, 1758, Sparus aurata L, 1758 and Mugil cephalus L, 1758 from the Camlik lagoon of the eastern cost of Mediterranean (Turkey)

    In this study, bioaccumulation of the heavy metals (Fe, Zn, Cd) in the liver, gill, gonad and muscle tissues of Dicentrarchus labrax, Mugil cephalus and Sparus aurata were investigated seasonally. Camlik is the important fisheries lagoon located in The Iskenderun Bay, Mediterranean cost of Turkey. Due to heavy industrial and agricultural activities in the region, the bay has the polluted coastal waters of Turkey. Therefore, the levels of cadmium, zinc, iron were determined in the muscle in each species because of its importance for human consumption and also the liver, gill, gonad were analysed since these organs tend to accumulate metals. Heavy metal levels were found generally higher in the liver and gill than the gonad and muscle tissues in three species; the levels of all metals in a given tissue were generally higher in Mugil cephalus than the other two species. Data collected in this study suggest that Camlik lagoon is affected by a relatively metal pollution. The concentrations of Zn concentrations in the muscle tissues exceeded the acceptable levels for a food source for human consumption and other metals in the edible parts of the investigated fish were in the permissible safety levels for human uses.

    Solubility, structure and probable effects on marine environment of slag from the iron and steel works in Iskenderun
    (Ege Univ, 2006) Sarihan, Ercan; Avsar, Dursun; Goksu, M. Z. Lugal; Polat, Sevim; Cevik, Cem; Cevik, Fatma; Ozutok, Meltem
    Solubility, structure and probable effects on marine environment of slag that it is remnant from Iskenderun Iron and Steel Works examined between March and July 2005. For this purpose, the solubility of slag studied in seawater, pure water, rain water and mixture of sea and pure water. Concentration of heavy metals in seawater, sediment, seston and marine organisms investigated. While standard methods were used for the solubility experiments on the slag, AAS and GFAAS methods were used for heavy metal analyses. It has been seen that the slag did not dissolve in water under natural conditions. The results of heavy metal concentrations, within seawater, sediment, seston and marine organisms, and the slimmer probability of dissolving of the slag with rainwater in the slag store area of the Iron and Steel Works showed that the slag was not a pollution factor for Iskenderun Bay from the heavy metal point of view.

    Variations of heavy metal levels of seston benthos and sediment seasonally in Camlik Lagoon (Karatas, Adana)
    (Ege Univ, 2006) Dural, Meltem; Goksu, M. Z. Lugal
    In this research, samples were taken seasonally from the Tuzla Lagoon and heavy metal (Cd, Pb, Cu, Zn, Fe) concentrations in the sediment, seston and benthos were measured. The concentrations of heavy metals in the seston, benthos and sediment samples were determined by using Flame Atomic Absorption Spectrophotometry (FLAAS) and Grafite Furnace Atomic Absorption Spectrophotometry (GFAAS) after wet digestion method. In recent years, decrease on the amount of local rainfalls, the lack of fresh and seawater sources, sedimentation, agricultural fields around the region, new domestic places and increasing salinity can be thought as the reasons of loosing the ecological balance in the lagoon. Results in this study showed that, in general, maximum bioaccumulation of Zn (2295,06 mu gg(-1)) and Cd (17,06 mu gg(-1)) was detected in seston, Fe (30441,70 mu gg(-1)) and Pb (67,29 mu gg(-1)) in sediment and maximum Cu (72,24 mu gg(-1)) levels were detected in benthos. As the conclusion, changes of detected levels of heavy metals on seston, sediment and benthos are seasonally independent.
