    Comparative Study of some Haematological Parameters in European Eel (Anguilla anguilla L., 1758) Caught from Different Regions of Ceyhan River (Adana, Turkey)
    (Ege Univ, Fac Fisheries, 2007) Sahan, Aysel; Altun, Tulay; Cevik, Fatma; Cengizler, Ibrahim; Nevsat, Erdal; Genc, Ercument
    This study was carried out in a agricultural, industrial, domestic and slaughterhouse discharging region (around Buyukmangit Village) of Ceyhan River and just under the dam's crest of Aslantas (Osmaniye) founded on the same river in the summer season of 2004. Water temperature, chemical oxygen demand (COD), pH, nitrate-nitrogen (NO3-N), nitrite-nitrogen (NO2-N), ammonia nitrogen (NH3-N), and soluble reactive phosphorus (SRP) values in these two stations were determined to the comparative effects of possible differences of water quality on haematological parameters. Forty fish were caught monthly from each station. Erythrocyte, leucocyte, haemoglobine (Hb), leucocyte cell (lymphocyte, monocyte, neutrophil, eosinophil) proportions and sizes of these cells of the fish were compared for two stations. As regard to water quality parameters, Station II was found in contaminated. Moreover, 75% of fish from Station II were found to be infested by swim bladder parasite Anguillicola crassus. In the study, leucocyte values and neutrophil proportion were found increased by means of environmental stressors (P< 0.05).

    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.
