1. 21. Halogenated organic matter in precipitation

   Författare :Krzysztof Laniewski; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : Deposition in rain and snow plays a crucial role in the regional and global redistribution of a great variety of substances. This thesis is devoted to chemical characterisation and identification of the halogenated organic compounds that are most widespread in rain and snow. LÄS MER

3. 22. Molecular-Level Investigations of Water-Organic Systems of Atmospheric Relevance

   Författare :Sofia M. Johansson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EMB method; desorption kinetics; water uptake; organic surfaces;

   Sammanfattning : It is known that aerosol particles may have warming and/or cooling effects on the climate and negative health effects that depend on their chemical and physical properties. However, current understanding of atmospheric particles’ effects is poor due to the diversity of their constituents and associated variations in properties. LÄS MER

4. 23. Seasonal and Long-Term Storage of Baled Municipal Solid Waste

   Författare :Diauddin Nammari; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pollution control; Environmental technology; Analytisk kemi; Analytical chemistry; Miljöstudier; Environmental studies; Waste storage; Poly aromatic hydrocarbons PAH ; Dioxin; Self ignition; Volatile organic compounds; GC-MS; Temperature; Interpolation; Baling; Cylindrical bales; Rectangular bales; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : Baling of MSW has been extensively used in Sweden and other countries for the storage of energy (biomass for energy) for incineration and production of either and or electricity and heat. Baling is performed in two principally different ways, leading to cylindrical- or rectangular bales. LÄS MER

5. 24. The Sink-Effect in Indoor Materials : Mathematical Modelling and Experimental Studies

   Författare :Peter Hansson; KTH; []
   Nyckelord :sink-effect; sorption; adsorption; diffusion; indoor air quality; volatile organic compounds; VOC; contaminants; building materials;

   Sammanfattning : In this thesis the sink-effect in indoor materials wasstudied using mathematical modelling and experimental studies.The sink-effect is a concept which is commonly used tocharacterise the ability of different indoor materials to sorbcontaminants present in the indoor air. The sorption process ismore or less reversible, i.e. LÄS MER

7. 25. Mixed metal oxide - noble metal catalysts for total oxidation of volatile organic compounds and carbon monoxide

   Författare :Magali Ferrandon; KTH; []
   Nyckelord :wood combustion; catalysts; total oxidation; manganese; copper; platinum; palladium; lanthanum; cerium; CO; VOC; methane; deactivation; thermal stability; sulphur dioxide;

   Sammanfattning : CO, volatile organic compounds, and polyaromatics areubiquitous air pollutants that give rise to deleterious healthand environmental effects. Such compounds are emitted, forinstance, by the combustion of wood, particularly fromsmall-scale heating appliances. LÄS MER
