   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Source-sorted waste; Household waste; Textile; Biofuel; Firewood; Pellets; Combustion; Wood boiler; Pellet boiler; Backyard burning; Garden waste; PCDD F; dioxin; PCB; Emission factor; Källsorterat avfall; Hushållsavfall; Textil; Biobränsle; Ved; Pellets; Förbränning; Vedpanna; Pelletpanna; Trädgårdsavfall; PCDD F; dioxin; PCB; Emissionsfaktor; Environmental chemistry; Miljökemi;

   Abstract : Denna avhandling behandlar rökgasutsläpp av persistenta organiska föroreningar, framförallt dioxiner, vid förbränning av fasta biobränslen och torrt hushållsavfall i relativt små anläggningar (5-600 kW) utan avancerad rökgasreningsteknik.Samförbränning av avfall och biobränsle i effektiva mindre biobränslepannor testades som en alternativ strategi till den vanligen förekommande storskaliga hanteringen och förbränningen fast hushållsavfall.

4. 2. Chemical Derivatization in Combination with Liquid Chromatography Tandem Mass Spectrometry for Detection and Structural Investigation of Glucuronides

   Author : Matilda Lampinen Salomonsson; Mikael Hedeland; Ulf Bondesson; Calle Nilsson; Uppsala universitet; []
   Keywords : Pharmaceutical chemistry; Derivatization; mass spectrometry; glucuronide; drug metabolism; increased sensitivity; structural investigation; 2-chloro-1-methylpyridinium iodide CMPI ; 1-ethyl-3- 3-dimethylaminopropyl -carbodiimide EDC ; 2-picolylamine PA ; 1; 2-dimethylimidazole-4-sulfonyl chloride DMISC ; Farmaceutisk kemi;

   Abstract : This thesis presents novel approaches for structural investigation of glucuronides using chemical derivatization in combination with liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MSn).Today, LC-ESI-MSn is the dominant technique for quantitative as well as qualitative analyses of metabolites, due to its high sensitivity and selectivity.

5. 3. Simplified Routines for Sample Preparation and Analysis of Chemical Warfare Agent Degradation Products

   Author : Raja Subramaniam; Calle Nilsson; Paula Vanninen; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nerve agents; Alkyl alkylphosphonic acids; Solid phase derivatization; Fluorinated diazomethane reagent; High-energy collision induced dissociation; CID MS MS library; analytisk kemi; Analytical Chemistry;

   Abstract : The thesis describes the development of new and improved methods for analyzing degradation markers from organophosphorus Chemical Warfare Agents (CWAs). Paper I and II describes an innovative and significantly improved method for the enrichment, derivatization (trimethysilylation) and GC-MS analysis of a broad range of organophosphorus CWAs degradation markers, namely the alkylphosphonic acids and a zwitterionic compound.

6. 4. Pollutant profiles as tools for characterisation of environmental exposure

   Author : Håkan Wingfors; Peter Haglund; Calle Nilsson; Georg Becher; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Multivariate; PCB; PAH; dioxin; PLS; Environment; road tunnel; Miljökemi; Environmental chemistry; Miljökemi; analytisk kemi; Analytical Chemistry;

   Abstract : This thesis is concerned with measurements of persistent organic pollutants (POPs) in environmental samples. The POPs consist of several groups of compound with many isomers, hence analysing POPs in a complex environment is a This thesis is concerned with measurements of persistent organic pollutants (POPs) in environmental samples.
