Persistent organic pollutants (POPs) in Pelagic systems
Article Abstract:
Research indicates that the excess nutrient discharge, or persistent organic pollutants, increases biomass and production, which in turn decreases the uptake ability of primary producers such as phytoplankton. The lower uptake results in greater eutrophication and a larger amount of pollutants settling into the organic sediment matrix, affecting the food chain.

Comparison of temporal trends (1940s-1990s) of DDT and PCB in Baltic sediment and biota in relation to eutrophication
Article Abstract:
A comparison is presented between sediment and biota data for the Baltic Sea over a 50-year range. Both sediment and biota samples show an increase in halogenated organic compounds from 1940 to 1950; however, biota information demonstrates a sharper decline in the levels of those compounds from 1970 to 1998 than the decline observed in sediment information.

Eutrophication and contaminants in aquatic ecosystems
Article Abstract:
A study is presented on the interaction between pollutants and eutrophication, focusing on the Baltic Sea. Environmental risks are found to be dependent on several factors, including contaminant speciation, media and matter association, substance mobility, and food chain pathways.
