Egirdir lake, located in the province of Isparta, the lakes region, is the one keeping most of the wetlands in Turkey. In this study, we determine heavy metal concentrations (Fe, Al, Cd, Cr, Co, Mn, Cu, Hg, B, Ni, Pb, and Zn) together with their spatial distribution, degree of pollution, and potential ecological risk in Egirdir Lake sediments. This region is wealthy in both floristic and faunistic aspects. Four different stations were chosen as sampling points. Samples were taken every three months, and the seasonal and annual average concentration of the elements was determined. The accumulated average heavy metal amounts were found ordered as Fe>Al>Mn>Cr> Ni> Pb>Zn>Cu>Co>Cd in bottom sediments, respectively. Hg and B were not determined in bottom sediments. Heavy metal contents were measured with ICP-OES. The results from analysis show high positive correlations among metals.
