    COMPARISON OF HEAVY METAL CONCENTRATIONS ON EUROPEAN CHUB (Leuciscus cephalus L., 1758) FROM SARICAY CREEK AND ATIKHISAR RESERVOIR (CANAKKALE - TURKEY)
    (Parlar Scientific Publications (P S P), 2015) Selvi, Kahraman; Kaya, Hasan; Akbulut, Mehmet; Tulgar, Arinc
    The aim of this study was to evaluate some heavy metals concentration (Zn, Pb, Cd, Cu, Fe and Mn) in the water and also in gill, liver, muscle, kidney tissues of European Chub species sampled from Atikhisar Reservoir and Saricay Creek. As a result of study, it was revealed that the heavy metal levels of the water samples, taken from Saricay Creek, are statistically higher than the samples, extracted from the Atikhisar Reservoir (p<0.05). All metals, examined within the tissues of the fish from Saricay Creek were also found out to be statistically higher than the ones from Atikhisar Reservoir (p<0.05). Consequently, this research suggest that the levels of Pb, Cd and Zn, accumulated in the fish samples, which were caught from Sal-way Creek, exceed the limits that are suitable for human consumption. In conclusion, it is estimated that the fish that may be consumed from Saricay Creek may impair to human health.

    Effects of sublethal concentrations of propargite to white blood cells of common carp (Cyprinus carpio, Linnaeus, 1758)
    (Adem Yavuz SÖNMEZ, 2015) Tulgar, Arinc; Celik, Ekrem Sanver
    In this study, effects of propargite, an organosulphiric pesticide were investigated in carp’s (Cyprinus carpio) white blood cells such as lymphocyte (LYM), neutrophile (NEU), monocyte (MON), basophile (BAS) and eosinophile (EOS). Fish were exposed to control (only distilled tap water), low (0.04125 ppm), medium (0.0825 ppm) and high (0.165 ppm) concentrations of propargite. As a result of study, percentage of BAS, NEU and MON cells were generally showed an increase on the 14th day compared to the control group, in case percentage of LYM and EOS cells were decreased on the 14th day according to the control group. In conclusion, changes observed among the white blood cell types could demonstrate the immunosupresive effect of propargite.

    THE USE OF BIOMARKERS TO DETERMINE THE EFFECTS OF WATER POLLUTION ON THE ODONATA LARVAE, Aeshna affinis, IN SARICAY CREEK (CANAKKALE-TURKEY)
    (Parlar Scientific Publications (P S P), 2014) Kaya, Hasan; Selvi, Kahraman; Akbulut, Mehmet; Tulgar, Arinc
    The use of biomarkers in pollution monitoring studies is well-established, but the type of biomarkers which are suitable for use under oxidative stress conditions in this field is not well-known. In this study, biomarker responses to Na+, K+-ATPase, glutathione (GSH) and thiobarbituric acid reactive substances (TBARS) were examined, in the presence of water pollution caused by Aeshna affinis, on odonata larvae collected from Saricay, some parts of which are subject to domestic, industrial and agricultural pollution. As a result of the study, a significant increase was observed in GSH and TBARS levels in Aeshna affinis individuals collected from the polluted area compared with the living organisms collected from the unpolluted area (p<0.05) whereas a considerable inhibition of Na+, K+-ATPase enzyme activity was discovered (p<0.05). The findings of the study suggest that the polluted area of Saricay is under oxidative stress from water pollution by Aeshna affinis, which is, however, tolerated by an antioxidant defense system. In addition, the biomarkers used in this study appear to be suitable indicators to see the effects of water pollution on living organisms.
