1. Natural aquatic colloidal matter : Characteristics and impact on the mobility of trace metals and organics
Abstract : Natural colloidal (< 1.0 µm) matter plays an important role for tbe transport and redistribution of water-borne substances. The aim of this work was to characterise colloidal matter from surface waters and groundwaters, and to improve on the understanding on the role of natural colloidal matter in the redistribution and mobility of trace metals.

2. Lake sediment as environmental archive : natural and anthropogenic influence on the chronology of trace elements
Abstract : The focus of this thesis is the historical pollution of some seldom-monitored trace elements (SMTEs; Ag, Be, Ga, In, Sb and Tl) that have been involuntarily released for several thousands of years but whose usage have increased during the industrial era. Sediment cores from four rural lakes in a south to north transect in central Sweden, and two urban lakes have been used as environmental archives for chronological studies. READ MORE

3. Rapid analysis of actinide isotopes using quadrupole ICP-MS for emergency preparedness and environmental monitoring
Abstract : Transuranium elements in the environment are mainly derived from nuclear weapons testing and the nuclear fuel cycle. Of growing concern are illicit nuclear trafficking and the threat of terror acts. READ MORE

4. Capillary zone electrophoresis for the analysis of low molecular weight organic acids in environmental systems
Abstract : Capillary zone electrophoretic (CZE) methods were developed to identify and quantify low molecular weight (LMW) organic acids in environmental samples. Sensitivity and selectivity were optimised by adapting the background electrolyte to the characteristics of analytes, and by using different modes of detection and injection. READ MORE

5. Environmental levels of thallium : influence of redox properties and anthropogenic sources
Abstract : Thallium is a highly toxic element that humans are exposed to mainly by consumption of drinking water and vegetables grown in soil with high thallium content but also through inhalation of particles in the air. Thallium is also present in fossil fuels, alloys, and in electronic utilities. READ MORE
