  3. 2. Biological, physico-chemical and biogeochemical dynamics of hydrophobic organ compounds

    Författare :Johan Axelman; Deborah L. Swackhamer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; zoologisk ekologi; Animal Ecology;

    Sammanfattning : This thesis presents new findings pertaining to several processes that govern the fate and effects of hydrophobic organic compounds (HOCs) in the environment. Two groups of HOCs, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), have been used as model compounds. LÄS MER

  5. 4. Ecological and physiological aspects of contaminant accumulation and transport by the filter-feeding mussel, Mytilus edulis

    Författare :Mikael Björk; Jussi Kukkonen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Marine Ecotoxicology; marin ekotoxikologi;

    Sammanfattning : This thesis examines the influence of food availability on the bioaccumulation kinetics and the transport of hydrophobic organic contaminants (HOCs) by the Baltic Sea blue mussel, Mytilus edulis. In laboratory studies, food availability was found to significantly modify the rate of physiological processes involved in filter-feeding. LÄS MER
