Seaports affect the environment through various functions related to cargo handling, connectivity sea and land transport networks, industrial, logistics, distribution activities. The purpose of this study was perform a preliminary assessment contents dioxins microplastics in bottom sediments Port Gdynia. identification plastic particles carried out on basis visual microscopic observations, as well spectroscopy analysis. Fragments fibres were dominant when categorised by particle shape, while transparent, white, black dominated colour. predominant polymer types identified polyolefins their derivatives. These findings suggest that low-density plastics are present seabed sediments, probably result biofouling. Samples also tested for presence dioxins. In sediment surface layer, highest concentrations obtained octachlorodibenzo-p-dioxin (5.54–962 ng/kg d.m.), which has low toxicity. most toxic congener (2,3,7,8-tetrachlorodibenzo-p-dioxin) very (0.19–0.32 s.m.). values toxicity coefficient ranged from 0.01 9.77 s.m. results showed studied zones Gdynia Port, analysed pollutants do not cause high ecological risk require permanent monitoring.
