“…The metals can move with the food chain. For this reason, detection of trace metal levels in rivers is an important indication for environmental pollution (Vaisanen et al 1998;Polat 1998;Barlas 1995;Tunay 1996;Cirik 1995;Uslu 1998;Karpuzcu 1991;WHO 1984;Singh and Kumar 2006;Dolgova and Kudryavtseva 2006). Therefore, various methods have been developed to determine levels of many metals in water and soil.…”

Different sources of pollution in Karasu Creek were investigated to obtain the water quality and ratio of contamination in this region. To achieve the main objectives of the present study, water samples were collected from Karasu Creek, starting from flow pattern at the upstream site of Akkaya Dam to the end of the dam, crossing the place where the Creek drains into. Dissolved oxygen, electrical conductivity, temperature and maximum/minimum pH were measured systematically for 12 months in the stations, where the water samples were collected. Chemical analyses of the water samples were carried out by using Cadas 50 S brand UV spectrometer to find out the Pb, Fe, Cu, Zn, Ni, Cr, Cd, S, F and Cn concentrations. These concentration were determined in microg/lt as 80-850; 180-4,920; 10-6,100; 440-25,530; 130-2,400; 120-280; 20-150; 214,250-1,113,580; 1,560-4,270 and 40-690, respectively. To determine metal levels of the water samples, multivariate analyses (element coefficient correlation, coefficient correlation dendrogram, hierarchical cluster analysis dendrogram, model summary and ANOVA) were used. The analyses yielded highly accurate results. There were positive correlations between some elements and their possible sources were the same. The stations which resembled each other along the creek were divided into three groups. The water quality of the creek was low and had toxic qualities. Eutrophication developed in Akkaya Dam along the creek. The source of pollution was thought to be industrial and residential wastes. Absolute (0-100 m), short distance (100-500 m) and medium distance (500-2,000 m) conservation areas should be determined in pollution areas along Karasu Creek and they should be improved.
