  2. 1. Bioavailability of organic contaminants in a changing climate

    Author : Matyas Ripszam; Peter Haglund; Roland Kallenborn; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; organic contaminants; sorption; dissolved organic carbon; bioavailability;

    Abstract : The effects of predicted future climate change was investigated with special emphasis on the association of organic contaminants with dissolved organic carbon (DOC) in the Baltic Sea.An automated method was developed for the measurements of DOC - water distribution constants at realistic DOC concentrations in brackish water.

  5. 3. Association of hydrophobic organic compounds to organic material in the soil system

    Author : Silviu-Laurentiu Badea; Mats Tysklind; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HOCs; Organic Matter; Clay; DOM; Environmental Science; miljövetenskap;

    Abstract : Contaminated soils and sediments have been identified as significant secondary sources of organic contaminants.  Leaching tests may be useful tools to estimate the mobility of contaminants via the water phase and thereby the risk for groundwater and surface water contamination.

  6. 4. Contaminated sediments: Methods to assess release and toxicity of organic chemical mixtures

    Author : Lukas Mustajärvi; Anna Sobek; Jarkko Akkanen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sediment; Hydrophobic organic contaminants; Flux; Bioturbation; Passive sampling; Passive dosing; Mixture toxicity; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Bottom sediments around the world store large amounts of legacy hydrophobic organic contaminants (HOCs), forming mixtures of unknown chemical composition. Primary emissions to the environment of many HOCs have been reduced as a consequence of regulation. READ MORE

  7. 5. Tools for Evaluating the Fate and Bioaccumulation of Organic Compounds in Aquatic Ecosystems

    Author : Erick Nfon; Ian Cousins; Jan Hendriks; Stockholms universitet; []
    Keywords : Baltic Sea; Biomagnification; Exposure; Food web; Fugacity model; Stable isotopes; Organic contaminants; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The bioaccumulation of organic contaminants in aquatic ecosystems has been a key focus in environmental toxicology over the last decades. Bioaccumulation is a key concept in ecological risk assessments since it controls the internal dose of potential environmental contaminants. READ MORE
