ABSTRACT: The risk associated with the exposure of humans and the environment to the impact of toxic compounds such as dioxins is associated with a number of factors such as: the level of contamination, environmental conditions and the dynamics of the food chain. The aim of the study is to provide a primary understanding of the risk of dioxins pollution in bottom sediments of the Port of Gdynia. The research was conducted to obtain data on the presence, concentration and risk assessment of PCDD/Fs in the bottom sediments of the Port of Gdynia. Sediments from five port basins were analyzed by GC-MS/MS and all PCDD/Fs congeners, capable of accumulating in fat cells of organisms, were detected in them. PCDD congeners dominated in the sediments. The highest concentration (902 ng/kg d.w.) was obtained for OCDD, dioxin with the lowest toxicity factor. The concentration of all 17 dioxin congeners (WHO-TEQ) ranged from 0.9 to 9.5 ngTEQ/kg d.w. Thus, bottom sediments from examined zones of port basins do not have a negative impact on the environment.
