11. Development of Fast, Quantitative, Selective and Bioavailability-Predictive Extraction Procedures for Determination of Halogenated POPs in Environmental Matrices
Sammanfattning : This thesis concerns the analysis of anthropogenic substances of the compound class known as persistent organic pollutants (POPs). Sample preparation perspectives for the analysis of POPs in the environmental matrices water, soils and sediments are presented. LÄS MER
12. Towards an accurate determination of lignin in chemical pulps : The meaning of kappa number as a tool for analysis of oxidable groups
Sammanfattning : Lignin content is the most important parameter in chemicalpulping. At present, kappa number is the most common parameterfor determination of lignin content and the base for otheron-line methods and for industrial automation (Chapter 1). LÄS MER
13. Electric DNA arrays for determination of pathogenic Bacillus cereus
Sammanfattning : Silicon-based electric chip arrays were developed for characterization of Bacillus cereus with respect to the capacity to produce toxins involved in food poisoning and foodborne infections. Bacteria of the B. cereus group contain different sets of four toxins encoded by eight genes. LÄS MER
14. Inductively Coupled Plasma Atomic Emission Spectrometry : Exploring the Limits of Different Sample Preparation Strategies
Sammanfattning : This thesis describes two different sample preparation strategies for inductively coupled plasma atomic emission spectrometry (ICP-AES), and their ability regarding multi element quantification in complex samples. Sensitivity, repeatability, reproducibility and accuracy were investigated. LÄS MER
15. Light conditions in seasonally ice-covered waters : within the Baltic Sea region
Sammanfattning : Seasonal ice cover is a major driver of seasonality in aquatic ecosystems in the Baltic Sea region. Ice cover influences the underwater light conditions directly by limiting the light transfer and indirectly by modifying the mixing and circulation under the ice. LÄS MER
