  2. 1. Simplifying complex models : Application of modeling tools in exposure assessment of organic pollutants

    Author : Emma Undeman; Michael McLachlan; Kathrin Fenner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mass balance model; environmental modeling; exposure modeling; bioaccumulation; organic contaminants; emission estimate; plant model; steady state; poly parameter linear free energy relationship; PPLFER; ecosystem susceptibility; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Thousands of chemicals are used in society, but the exposure to humans and other organisms has been measured only for a small number of compounds. Modeling tools constitute low-cost and effective alternatives to measurements for the assessment of exposure. READ MORE

  4. 2. Binding of benzo(a)pyrene metabolites and derivatives to DNA : characterization using optical spectroscopy techniques

    Author : Ola Undeman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : DNA with covalently bound benzo(a)pyrene (BP) derivatives was studied with fluorescence spectroscopy, fluorescence decay measurements, fluorescence quenching measurements, light absorption and linear dichroism of flow oriented samples. The modified DNA was prepared in three different ways: (1) by incubating calf thymus DNA with rat liver micromomes, necessary cofactors and benzo(a)pyrene or derivatives of benzo(a)pyrene, (2) by isolating DNA.

  5. 3. Simulating Transport and Understanding Future Fluxes of Organic Carbon in Rivers Draining into the Baltic Sea

    Author : Kim Dahlgren Strååt; Emma Undeman; Martyn Futter; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Riverine organic (TOC, Total Organic Carbon) and inorganic (DIC, Dissolved Inorganic Carbon) carbon are the main sources of carbon in the Baltic Sea. While the importance of this contribution has been evaluated, there are currently several gaps in our knowledge of the mechanisms governing organic carbon dynamics in this region, especially for the particulate form, and the impact of future climate change on organic carbon transport.
