title: The relationship between the concentrations and distribution of organic pollutants and black carbon content in benthic sediments in the Gulf of Gdańsk, Baltic Sea.
abstract: The influence of the sediment's physico-chemical properties and black carbon content, on the distribution of polycyclic aromatic hydrocarbons and polychlorinated biphenyls in benthic sediments of the Gulf of Gdansk (Baltic Sea) was determined. Sediments from port, marine dump site of dredged spoils, the Vistula river mouth, Gdansk Deep were selected. The concentrations of ∑PAHs (fluoranthene, pyrene, benzo(a)anthracene, benzo(k)fluoranthene, benzo(a)pyrene, dibenzo(ah)anthracene, benzo(ghi)perylene) were 294-2200 ng/g d.w. and for ∑PCBs (28, 52, 101, 118, 138, 153, 180) were 2.4-11.3 ng/g d.w. The sediments content of loss on ignition was 1.13-16.15%, total organic carbon was 0.89-7.15%, black carbon was 0.20-1.15%. The highest correlation coefficient values (r=0.76-0.92, p<0.05) for a relationship between the concentrations of organic pollutants, and organic matter, organic and black carbon contents were obtained in harbor sediments with low content of organic matter (<5%) and high share of black carbon in total carbon (up to 40%).
