Presence, concentrations and risk assessment of dioxins in bottom sediments of Port of Gdynia
Summary
Researchers measured dioxin concentrations in bottom sediments at the Port of Gdynia, Poland, and assessed associated ecological risks. Dioxins are persistent toxic pollutants that, like microplastics, accumulate in marine sediments and can harm aquatic organisms and seafood consumers.

Determination of Selected Organic Contaminants in the Port of Gdynia Sediments: Towards Cleaner Baltic Ports
Researchers assessed dioxin and microplastic contamination in bottom sediments from the Port of Gdynia on the Baltic Sea, providing preliminary baseline data on organic pollutants and plastic particles in a major European seaport. Polyolefins were the dominant plastic types identified by spectroscopic analysis.
Microplastics in Harbour Seawaters: A Case Study in the Port of Gdynia, Baltic Sea
Microplastics were measured in five basins of the Port of Gdynia in the Baltic Sea across four seasons, finding concentrations of 0.082-0.524 mg per cubic meter, with polyolefins dominant and fragments and fibres the most common shapes in harbour surface waters.
The sorption of persistent organic pollutants in microplastics from the coastal environment
Researchers sampled microplastic pellets from six beaches around Taiwan and measured concentrations of persistent organic pollutants (dioxins, PCBs, PBDEs) on their surfaces, finding that pellets accumulated significant POPs loads with concentrations that correlated with proximity to industrial areas.
Microplastics in ports worldwide: Environmental concerns or overestimated pollution levels?
This review analyzed microplastic pollution data from 78 ports worldwide and found that port environments can harbor significant concentrations of microplastics in water, sediment, and marine life. About 23% of studied ports had microplastic levels in sediment above the threshold predicted to cause ecological harm. Since ports are connected to fisheries and coastal communities, this pollution could affect both marine ecosystems and the seafood supply chain.
Assessment of ecological risk for ecosystems caused by dredged materials in freshwater environments
Researchers assessed ecological risks posed by chemical contaminants in dredged freshwater sediments, evaluating metals, organic pollutants, and emerging contaminants including microplastics across multiple risk metrics to inform safe disposal and management decisions.
