Abstract In this paper was investigated the influence of drying technique on oil amount in sediments. Drying techniques used for sediments were oven at 600C or freeze dryer. For the comparison of the results wet and dried of sediments the highest oil pollution level was found in freeze drying technique. The comparison of the oil amount found in freeze drying sediment are 20 time fold wet weight method and two time fold oven method. The best results were obtained for freeze dryer method in tested techniques. Instead of the results showed that a seriouse lack exist for the determination of oil concentration in sediment.
