In this work the oil and detergent pollutions were investigated in sea water, near the refinery of TUPRAŞ and Ali Ağa, Istanbul Strait, Golden Hom and Çanakkale Strait. The pollutions were higher in refinery areas. The results inadequate that there is apparently no regular seasonal variation in oil and detergent amount. The maximum oil concentration in sea water was found 29.55 µg/L for Istanbul Strait 4214.29 µg/L for Golden Hom and 42.96 µg/L for Çanakkale Strait in 19.02.2005 and 90.02 µg/L for TUPRAŞ 3, 71.77 µg/Lfor Ali Ağa 2, in 07.Agust. 2006., in sediment 9573.38 µg/g for Istanbul Strait, 1126.45 µg/g for Golden Horn, 31.52 µg/g for Çanakkale Strait in 21.02.2005, 1500.6 µg/g for TUPRAŞ in 13.11.2006, 58.64 µg/g for Ali Ağa in 7.12.2006. These oillevels found are higher than the limit values for sea water and sediment. The LAS levels found are similar in earIier findings of this area.
