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...

Thermal formation and chlorination of dioxins and dioxin-like compounds
Author(s) :
Jansson, Stina
Description :
This thesis contributes to an increased understanding of the formation of dioxins and dioxin-like compounds in combustion processes. Although emissions to air from waste incineration facilities have been greatly reduced by the use of efficient air pollution control measures, the resulting residues (...

Effects of Varying Combustion Conditions on PCDD/F Formation
Author(s) :
Aurell, Johanna
Description :
Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are by-products emitted from combustion sources such as municipal solid waste (MSW) incineration plants. These organic compounds are recognized as toxic, bioaccumulative and persistent in the environment. PCDD/Fs are...

Dioxin emissions from small-scale combustion of bio-fuel and household waste
Author(s) :
Hedman, Björn
Description :
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 bi...

Chlorinated organic pollutants in soil and groundwater at chlorophenol-contaminated sawmill sites
Author(s) :
Persson, Ylva
Description :
Mixtures of chlorinated organic pollutants can be found in the soils at chlorophenol-contaminated sawmill, including (inter alia) polychlorinated phenols (CPs), phenoxyphenols (PCPPs), diphenyl ethers (PCDEs), dibenzofurans (PCDFs) and dioxins (PCDDs). These hydrophobic compounds have low water solu...

Rapid sample preparation and bioanalytical techniques for efficient screening of organic pollutants in the environment
Author(s) :
Nording, Malin
Description :
Large numbers of samples often need to be prepared and analysed in surveys of organic pollutants in the environment, but while the methods commonly used in such surveys can provide abundant detail they are generally costly, time-consuming and require large amounts of resources, so there is a need fo...

Trace analysis of dioxins and dioxin-like PCBs using comprehensive two-dimensional gas chromatography with electron capture detection
Author(s) :
Danielsson, Conny
Description :
Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs), two groups of struc-turally related chlorinated aromatic hydrocarbons, generally referred to as “dioxins” are of great concern due to their extreme toxicity and presence in all compartments of the environment. Since they occur at v...

Properties and analysis of dioxin-like compounds in marine samples from Sweden
Author(s) :
Lundgren, Kjell
Description :
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. In a near future, there might be other dio...
