1. Properties and analysis of dioxin-like compounds in marine samples from Sweden
Abstract : Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (PCBs) have been assigned toxic equivalency factors (TEFs). These compounds are today routinely analysed with sophisticated analytical techniques. READ MORE

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

3. Analytical methods for studying polychlorinated naphtalene congener profiles and levels in the Environment
Abstract : This thesis describes the development, refinement and application of analytical techniques in conjunction with other methods for studying the environmental occurrence, distribution and transformation of polychlorinated naphthalenes (PCNs). The procedures involve selective high-performance liquid chromatographic fractionation on a styrene-divinylbenzene gel permeation column and 2-(1-pyrenyl)ethyldimethylsilylated silica column combined with high resolution gas chromatography and low resolution mass spectrometry.

4. The relationship between fly ash chemistry and the thermal formation of polychlorinated pollutants during waste incineration
Abstract : The thermal formation of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), biphenyls (PCBs), and naphthalenes (PCNs) is a major problem in waste incineration. Ideally, rather than relying on air cleaning systems and treatment techniques, their formation should be minimized or, if possible eliminated. READ MORE

5. Studies on organochlorine environmental contaminants with emphasis on analytical methods and occurrence in humans
Abstract : Methods for multicomponent analysis of lipophilic organochlorine contaminants(OCs) in blood plasma and lipid-rich tissues are presented. By using the described methods, polychlorinated biphenyls (PCB), polychlorinated naphthalenes (PCN), hexachlorobenzene(HCB), 1,1-dichloro-2,2-bis(4 chlorophenyl)ethene (p,p'-DDE) and methylsulphonyl metabolites of PCB (MeSO2-PCB) and p,p'-DDE (Meso2-DDE) were determined in human blood plasma, adipose tissue and liver.
