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. Emissions of volatile organic compounds from wood

   Author : Karin Granström; Bengt Månsson; Ann-Margret Strömvall; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOC; terpenes; drying; wood; emissions; spouted bed; Environmental engineering; Miljöteknik; Miljö- och energisystem; Environmental and Energy Systems;

   Abstract : The central aim of this thesis is to support the efforts to counteract certain environmental problems caused by emissions of volatile organic compounds. The purpose of this work was (1) to develop a method to establish the amount of emitted substances from dryers, (2) to determine the effect of drying medium temperature and end moisture content of the processed material on emissions of monoterpenes and other hydrocarbons, (3) to examine the emissions of monoterpenes during production of pellets, and (4) to examine the natural emissions from forests with an eye to implications for modelling.

5. 3. Nitrogen-containing products from atmospheric oxidation of volatile organic compounds

   Author : Epameinondas Tsiligiannis; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; VOC; anthropogenic; biogenic; SOA; atmospheric oxidation; organic aerosols; CIMS; FIGAERO; TMB; isoprene; HOM; organonitrates ONs ; NOx; OH; nitrate NO3 ; Go:PAM; SAPHIR;

   Abstract : Atmospheric oxidation of volatile organic compounds (VOC) produces a wide range of oxygenated organic products that lead to formation of secondary organic aerosol (SOA). SOA represents a significant fraction of the tropospheric aerosol that influence climate and human health. READ MORE

6. 4. Designing Quinone-based Organic Batteries

   Author : Christian Strietzel; Martin Sjödin; Philippe Poizot; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conducting polymers; organic electronics; quinones; organic battery; electrochemistry; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

   Abstract : The demand for secondary energy storage is ever increasing, being at the forefront of the transformation to a sustainable society. Conventional batteries, whose electrode materials require mining and high temperature refining, generate substantial carbon dioxide emissions during production. READ MORE

7. 5. Chemical emissions from building structures : emission sources and their impact on indoor air

   Author : Annika Glader; Ingrid Liljelind; Berndt Stenberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; VOC; building structures; emissions; health effects; moisture damage; PCA; OPLS; inomhusluft; VOC; konstruktioner; emissioner; hälsoeffekter; byggnadsmaterial; fuktskada; PCA; OPLS; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Abstract : Chemical compounds in indoor air can adversely affect our comfort and health. However, in most cases there is only a limited amount of information available that can be used to assess their health risk. Instead the precautionary principle is often applied, i.e. READ MORE
