  2. 1. In situ remediation of contaminated sediments using thin-layer capping : efficiency in contaminant retention and ecological implications

    Author : Göran S. Samuelsson; Jonas S. Gunnarsson; Bart Koelmans; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Contaminated Sediment Remediation; Activated Carbon; Benthic Community; Ecological Effects; Stress; Resilience; Contaminant Sequestration; Capping Efficiency; Bioavailability; Bioaccumulation; Sediment-to-water fluxes; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Hydrophobic organic contaminants (HOCs) often reside in sediments sorbed to particles, most tightly to particles with high content of organic carbon. If persistent, such pollutants can accumulate in the sediment for many years and constitute a contamination risk for sediment-living organisms and organisms at higher trophic levels, including humans.

  4. 2. Fate of contaminants in Baltic Sea sediment ecosystems : the role of bioturbation

    Author : Jenny E Hedman; Jonas Gunnarsson; Nils Kautsky; Valery Forbes; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Toxicology; Toxikologi; Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : Aquatic sediments are of major importance for the cycling of environmental pollutants, acting as both sinks and secondary sources of contaminants to the ecosystem. Sediment-living organisms can affect the fate and transport of contaminants through activities like feeding and burrowing, collectively called bioturbation. READ MORE

  5. 3. Phosphorus recycling in brackish and marine environments - Sediment investigations in situ in the Baltic Sea and the By Fjord

    Author : Lena Viktorsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phosphorus; sediment; anoxia; Baltic Sea; By Fjord; benthic flux;

    Abstract : The phosphorus load to the oceans from land started to increase since around 1950 when man started to mine phosphorus-mineral from phosphorus-rich soils and bedrock. The increased use of phosphorus fertilizers in agriculture together with the growth of coastal cities increased the load of phosphorus to the coastal ocean where plankton production flourished.
