Abstract

LAS pollution was determined in the Black Sea, Istanbul Strait and Sea of Marmara. The pollution level varied 4.38-24.01 µg/L at surface, 8.75-17.20 µg/L at 10 m., 7.55-24.61 µg/L at 30 m. and 8.55-26.08 µg/L at deep water in the Black Sea; 6.80-30.19 µg/L at surface, 1.26-19.79 µg/L at 10 m 5.66-32.17 µg/L at deep water in the northern entrance of Istanbul Strait; 3.66-20.17 µg/L at surface, 7.11-26.54 µg/L at 10 m, 4.19-67.09 µg/L at 30 m, 5.01-44.28 µg/L at deep water in southern entrance of Istanbul Strait; 1.26-28.98 µg/L at surface 1.59-45.64 µg/L at 10 m 6.01-29.21 µg/l at 30 m, 7.08-52.29 µg/L at deep water in the Sea of Marmara. Generally, the anion active substance amount was high in deep water and thermocline and decreased toward the surface water. The pollution level was high in the Sea of Marmara, lower in the Istanbul Strait than in the Black Sea.
