Abstract :The aim of this study is to determine the anthropogenic effects in lake Gala in the Thrace Region and to make an ecological risk analysis as a result of these effects. Based on the multi-element analyzes of the samples collected from the lake by Grab and Core method, using ICP-MS, which is frequently used in the calculation of ecological risk in sediment pollution studies; Ecological risk analysis of lakes with statistical analyzes such as Enrichment Factor insert ignore into journalissuearticles values(EF);, Contamination Factor insert ignore into journalissuearticles values(CF);, Geoaccumulation Index insert ignore into journalissuearticles values(Igeo);, Ecological Risk Index to Potential insert ignore into journalissuearticles values(PER);, Pollution Load Index insert ignore into journalissuearticles values(PLI);, Factor Analysis, Spearman\`s Correlation Analysis and Cluster Analysis has been made. According to the analysis results, very high contamination observed in Hg and high contamination values observed in Mn pose a remarkable threat to the ecosystem. We conclude that the lake is exposed to intense anthropogenic pressure due to agricultural wastes, industrial pollutants, domestic wastes and pollutants from transportation vehicles.
