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

    Författare :Göran S. Samuelsson; Jonas S. Gunnarsson; Bart Koelmans; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  3. 2. Photosynthetic water oxidation : the function of two extrinsic proteins

    Författare :Tatiana Shutova; Göran Samuelsson; Stenbjörn Styring; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photosystem II; Psb0; Cah3; water oxidation; Plant physiology; Växtfysiologi;

    Sammanfattning : The solar energy accumulated by photosynthesis over billions of years is the sole source of energy available on Earth. Photosystem II (PSII) uses the sunlight to split water, an energetically unfavorable reaction where electrons and protons are extracted from water and oxygen is released as a by-product. LÄS MER
