Ecotoxicological Effects of Solid Waste Storage Areas on Aquatic Systems: Example of Yedig ller, Kütahya

Yedig ller region where has been used as solid waste storage area of Kütahya since 35 years, consists of seven lakes including two dried lakes and the region is exposed to intense pollution. In the present study, samples were collected from the bigest lake of Yedig ller, which has an intensive fishing activity and some physicochemical parameters of lake water, such as pH, temperature, dissolved oxygen, % oxygen saturation, conductivity, salinity, nitrite, nitrate, phosphate, were determined. In addition, levels of some elements (Zn, As, B, Cd, Cr, Cu, Pb) were determined in water, sediment, and in the muscle of some fish species (Carassius gibelio (Bloch 1782), Squalius pursakensis (Hankó 1925) ve Capoeta sieboldii(Steindachner 1864)). Data obtained were evaluated according to the criteria of SKKY (Water Pollution Control Regulation) and TGK (Turkish Food Codex). Our results show that, the levels of As and Cd in fish muscle were detected as higher than the limit specified in the Turkish Food Codex. Furthermore, our results determined that, in terms of inorganic pollution parameters, the water quality of the Yedig ller was IV. class according to Continental Water Pollution Control Regulations for Domestic Water Supplies Quality Criteria.
