1. Isolation and identification of polycyclic aromatic compounds in complex matrices utilizing multidimensional chromatographic methods
Sammanfattning : .... LÄS MER
2. From source to the environment : Strategies for identification and determination of hydroxylated polycyclic aromatic hydrocarbons in complex particulate matrices
Sammanfattning : Adverse health effects have been linked to exposure to particulate matter, and wood combustion is considered as an important source of harmful particulate matter in the urban air and environment. Hydroxylated polycyclic aromatic hydrocarbons are a group of compounds with toxic, endocrine disrupting and carcinogenic properties. LÄS MER
3. Organophosphates and phthalates in air and dust from indoor environments : Method development and applied measurements
Sammanfattning : Organophosphate and phthalate esters are polymer additives that are frequently found in air and dust in indoor environments. This thesis describes the development and application of air sampling and selective mass spectrometric (MS) determination of these two compound groups. LÄS MER
4. Porphyrins and heme in microorganisms : Porphyrin content and its relation to phototherapy and antimicrobial treatments in vivo and in vitro
Sammanfattning : One of the greatest threats to human health is increasing antimicrobial resistance among pathogens, and finding alternatives for treatment of bacterial infections is of highest importance together with a more controlled use of antibiotics. Porphyrins and heme have both been shown to be a promising class of compounds for inactivation of bacteria; porphyrins by their excellent properties to act as a photosensitizer, and heme by its importance as an iron source during a bacterial infection in vertebrates.

5. Textile Related Chemicals: Analytical Approaches Towards the Assessment of Human and Environmental Exposures
Sammanfattning : The textile manufacturing chain involves an extensive use of chemicals as early as fabric-production. To confer special features to textile materials, more chemicals are required in subsequent steps. Furthermore, potentially harmful substances can end up in clothes as transformation products. LÄS MER
