Pollutant profiles as tools for characterisation of environmental exposure
Author(s) :
Wingfors, Håkan
Description :
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 pollutant...

On the combustion and photolytic degradation products of some brominated flame retardants Produkter från förbrännings- och fotokemisk nedbrytning av vissa bromerade flamskyddsmedel
Author(s) :
Söderström, Gunilla
Description :
Many modern products, especially electronic goods, are protected by brominated flame retardants (BFR). Some of the most common flame retardants are polybrominated diphenylethers (PBDE), tetrabromobisphenol-A (TBBP-A) and hexabromocyclododecane (HBCD). These compounds have been found in environmental...

Chemical reactions in ventilation systems : Ozonolysis of monoterpenes
Author(s) :
Fick, Jerker
Description :
Chemicals in indoor air, either emitted from a source or from a reaction, have been suggested to cause ill health in buildings. However, no clear correlations between exposure and health effects have been made. In this thesis we studied the reaction between monoterpenes, a group of biogenic unsatura...

Development of an Environment-Accident Index : A planning tool to protect the environment in case of a chemical spill Utveckling av Miljöolycksindex : Ett planeringsverktyg för att skydda miljön i händelse av kemikalieolycka
Author(s) :
Scott Andersson, Åsa
Description :
The increasing mass and complexity of chemicals being produced and transported has resulted in more rigorous demands on both authorities as well as chemical-handling industries to assess the risks involved. The Environment-Accident Index (EAI), has been proposed as a planning tool created as an equa...

Formation and degradation of PCDD/F in waste incineration ashes
Author(s) :
Lundin, Lisa
Description :
The disposal of combustible wastes by incineration is a controversial issue that is strongly debated by both scientists and environmental activists due to the resulting emissions of noxious compounds, including (inter alia) polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), heavy meta...

Determination of Antibiotics in the Swedish Environment with Emphasis on Sewage Treatment Plants
Author(s) :
Lindberg, Richard
Description :
Metoder har utvecklats för att kunna bestämma tolv antibiotikasubstanser, vanliga inom human medicin, i miljöprover. Fokus lades på trimetoprim samt substanser från följande grupper: fluorokinoloner, sulfonamider, penicilliner, cefalosporiner, nitroimidazoler, tetracykliner samt makrolider. Vid extr...

Deuterium isotopomers as a tool in environmental research
Author(s) :
Betson, Tatiana
Description :
This thesis describes the development and the use of quantitative deuterium Nuclear Magnetic Resonance spectroscopy (NMR) as a tool in two areas of environmental research: the study of long term climate-plant interactions and the source tracking of persistent organic pollutant. Long-term interaction...

Analysis of PCBs with special emphasis on comprehensive two-dimensional gas chromatography of atropisomers
Author(s) :
Harju, Mikael
Description :
There are 209 PCB congeners, 136 of which have been found in technical PCB mixtures and hence may be found in the environment as a result of either intentional or unintentional release. The identification and quantification of the congeners are difficult due to analytical bias from coeluting PCBs an...

Hazard screening of contaminated sites : bioavailable fractions and biological in vitro tools
Author(s) :
Ragnvaldsson, Daniel
Description :
The environmental bioavailability of contaminants, rather than their total concentrations in the soil compartment play a decisive role for the risks associated with contaminated sites. Various soil constituents and abiotic conditions have strong influence on bioavailability, which may vary substanti...

PLE with integrated clean up followed by alternative detection steps for cost-effective analysis of dixons and dioxin-like compounds
Author(s) :
Spinnel, Erik
Description :
Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are two structurally related groups of chemicals, generally referred to as `dioxins´. These are of great concern due to their high toxicity and global spread. Other groups of compounds with similar chemical structure...
