    Abstract : The work presented in this thesis concerns the development and evaluation of new methods of sampling and analysis of organic pollutants in the indoor and outdoor environment. In Paper I, the development of a new method was reported for the determination of the brominated flame retardant tetrabromobisphenol A (TBBPA) in air using sampling with glass fiber filter and polyurethane foam (PUF), ultrasonic solvent extraction and liquid chromatography coupled to electrospray ionisation mass spectrometry (LC-ESI/MS).

  4. 17. Biomarkers aiming at cancer risk estimation of polycyclic aromatic hydrocarbons

    Author : Hans Helleberg; Kimmo Peltonen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical Biology; fysikalisk biologi;

    Abstract : Polycyclic aromatic hydrocarbons (PAH), a family of compounds that are formed in incomplete combustion of organic matter, occur as general pollutants in air and food. Exposure to PAH is, according to preliminary estimates, associated with non-acceptable cancer risks showing the need for improved data to be used in risk estimation. READ MORE

  7. 20. The accessibility and chemical activity of polycyclic aromatic hydrocarbons in soil

    Author : Fredrik Reichenberg; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; Remediation; Bioavailability; Soil and sediment pollution; Environmental chemistry; Miljökemi;

    Abstract : This thesis proposes the use of two concepts: accessibility and chemical activity. Accessibility describes the mass quantity of PAHs that is or can become available within a given time span and under given conditions. READ MORE
