1. Chlorinated organic pollutants in soil and groundwater at chlorophenol-contaminated sawmill sites
Sammanfattning : Mixtures of chlorinated organic pollutants can be found in the soils at chlorophenol-contaminated sawmill, including (inter alia) polychlorinated phenols (CPs), phenoxyphenols (PCPPs), diphenyl ethers (PCDEs), dibenzofurans (PCDFs) and dioxins (PCDDs). These hydrophobic compounds have low water solubility and hence low mobility as truly dissolved compounds. LÄS MER
2. Dioxins and dioxin-like compounds in thermochemical conversion of biomass : formation, distribution and fingerprints
Sammanfattning : In the transition to a sustainable energy supply there is an increasing need to use biomass for replacement of fossil fuel. A key challenge is to utilize biomass conversion technologies in an environmentally sound manner. LÄS MER
3. Association of hydrophobic organic compounds to organic material in the soil system
Sammanfattning : 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. LÄS MER
4. The wild male mink as a sentinel for endocrine-disrupting chemicals and reproductive toxicity
Sammanfattning : Increasing evidence indicates that pollutants may affect the hormone system of humans and wildlife. These endocrine-disrupting chemicals are related to an increased risk of a variety of diseases and disorders, including adverse effects on the reproductive system. LÄS MER
5. Role of Lipids in the fate of organochlorine compounds in Aquatic Ecosystems
Sammanfattning : Both results of laboratory experiments and material collected in the field have shown the lipid composition in organisms to have a significant effect on the bioaccumulation of pollutants and on the lipid steady-state concentrations of pollutants there. The redistribution of persistent organic pollutants which occurs in organisms as a consequence of the depletion of lipid depot, was studied in a population of migrating Pacific salmon (Oncorhynchus nerka).
