ABSTRACT
Alkylphenol polyethoxylates (APEs) called environmental endocrine disruptors has been shown to accumulate in water around the world. In this study, the pollution level of alkylphenolic compounds was measured and quantified in water, sediment, and the tissues of fishes collected in two rivers, Sakarya and Degirmendere Rivers, Turkey. Butylphenol (BP) were detected in sediment samples at one sampling stations of both rivers with 1.68 and 3.15 µg/g sediment, while nonylphenol (NP) were detected with the amount of 4.46 µg/g sediment in one sampling station in Degirmendere river. Fish samples also showed the presence of alkylphenolic compounds in both rivers. The level of alkylphenol pollution in two rivers of Turkey was determined to be in the range of alkylphenol level reported in Europe but lower than that of in the USA.
