2. 1. Colloidal Organic Pollutants in Road Runoff: Sources, Emissions and Effective Treatment Technologies

   Author : Anna Markiewicz; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; organic pollutants; nanoparticles; stormwater; sorption filters; road dust; emulsions; washwater; vehicle wash; road runoff; microparticles; sweepsand; colloids; street sweeping;

   Abstract : Thousands of organic substances circulate in our society and are diffusely emitted through traffic, combustion and leaching from constructions and building materials into the urban environment. The research in this PhD thesis focuses on road runoff as the highest concentrations of pollutants are frequently found in runoff from areas with high traffic intensity. READ MORE

4. 2. Persistent organic pollutants in benthic foodwebs

   Author : Niklas Holmqvist; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; limnologi; Marinbiologi; limnology; aquatic ecology; marine biology; Hydrobiology; Ekologi; Ecology; Intraspecific interactions; streams; nutrients; lakes; crayfish; eels; Persistent organic pollutants; Benthic foodwebs; akvatisk ekologi; Environmental chemistry; Miljökemi;

   Abstract : Concentrations of persistent organic pollutants (POPs) in aquatic biota are dependent on several factors both on individual and on system level. Bioaccumulation of POPs in pelagic biota in lakes as well as fish in streams has been shown to be dependent on nutrient regime of the system. READ MORE

5. 3. Towards International Chemical Safety : Taking Action on Persistent Organic Pollutants

   Author : Henrik Selin; Loftsson Elfar; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Convention on Long-Range Transboundary Air Pollution CLRTAP ; persistent organic pollutants POPs ; regime analysis; social learning; Miljö; Föroreningar; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Abstract : Persistent organic pollutants (POPs) have been subject to increased international ro-operation over that past decade. The first international effort to address POPs collectively as a distinet class of pollutants was made under the United Nations Economic Commission for Europe (UNECE) and within the framework of the Convention on Long-Range Transboundary Air Pollution (CLRTAP), which geographically covers North America, Europe and the region of the former Soviet Union.

6. 4. Human exposure to persistent organic pollutants : Illustrated by four case studies in Europe

   Author : Jana Weiss; Åke Bergman; Janice Huwe; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human exposure; Persistent organic pollutants POPs ; Environmental chemistry; Miljökemi;

   Abstract : An extensive use of chemicals in countless consumer products has resulted in human exposure to several persistent organic pollutants (POPs). Sufficient knowledge about their chemical composition properties and environmental faith is required, to be able to proper risk assess and regulate the substances. READ MORE

7. 5. Dioxins and dioxin-like compounds in thermochemical conversion of biomass : formation, distribution and fingerprints

   Author : Qiuju Gao; Stina Jansson; Bogdan Dlugogorski; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polychlorinated dibenzo-p-dioxins; polychlorinated dibenzofurans; polychlorinated naphthalenes; PCDD; PCDF; PCN; persistent organic pollutants; torrefaction; pyrolysis;

   Abstract : 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. READ MORE
