Marine ecosystems face a significant ecological challenge due to the introduction and cycling of hazardous substances. The recent stabilization concentrations specific substances, which were previously decreasing, indicates ongoing processes within ecosystem. These continue make these substances available food chain, even following implementation restrictions elimination known anthropogenic sources. present study investigated transfer mercury, PBDEs, PCBs their congeners via trophic by combining consumer dietary characteristics pollutants using European perch (Perca fluviatilis) its prey as model organisms. elevated mercury accelerated magnification in population at one sampling sites appear be linked selective consumption Decapoda. However, frequency occurrence any particular item diet does not account for declining slopes site. Furthermore, distant sites, PBDEs do exhibit consistent slopes. This suggests significance pollution loads neighboring water bodies migration patterns assessed species.
