In this study anionic detergent, LAS concentration was surveyed in the coastal surface water of the Turkish Straits System (TSS) in January and August of 2012. Samples were taken at 15 stations in the TSS, which consists of Straits of Istanbul and Çanakkale and the Sea of Marmara. The mean value of LAS was found for January in the Istanbul Strait as 22.88 μg/L, in the Çanakkale Strait as 24.24 μg/L, in the Sea of Marmara Sea as 26.06 μg/L and for August in the Istanbul Strait as 43.43 μg/L, in the Çanakkale Strait as 48.25 μg/L, in the Sea of Marmara as 42.15 μg/L. The highest pollution was found at Kadıköy and the lowest at Anadolu Feneri for both months. Significant differences were found between seasons (p<0.05).
