Abstract
Meric River Delta is located in the Thrace Region of Turkey, and it is one of the most important wetlands worldwide. Gala and Sigirci Lakes, which are known as significant lakes in Turkey in terms of especial biodiversity, are located in the Meric River Delta and they are the main lentic factors of the system. The aim of this study was to evaluate the essential and toxic element bioaccumulation levels in fishes of Gala and Sigirci Lakes from a statistical perspective by investigating a total of 25 macro- and micro-element bioaccumulations. One-Way ANOVA Test (OWAT) was applied to detected data in order to determine the statistical differences of element bioaccumulations among the fish species. Cluster analysis (CA) was also applied to detected data in order to classify the investigated elements in terms of bioaccumulation levels in fish tissues. According to the results of OWAF, although statistical differences were not recorded among the fish species in terms of essential element levels, significant statistical differences were recorded in terms of toxic element levels (P<0.05). According to the results of CA, 5 statistically significant clusters were formed, which were named as Most intense elements, Second most intense elements, Moderate intense elements, Second rarest elements, and Rarest elements. It was also found that toxic element bioaccumulation rates in fishes of Gala Lake were significantly higher than in fishes of Sigirci Lake (P<0.05).
