  4. 2. Environmental levels of thallium : influence of redox properties and anthropogenic sources

    Author : Ulrika Karlsson; Stefan Karlsson; Anders Düker; Roger Herbert; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thallium; Tl I ; Tl III ; separation; ion chromatography; fresh water; sediment; mine waste; fly ash; redistribution; ICP-MS; Environmental chemistry; Miljökemi; Kemi; Chemistry;

    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

  5. 3. Lake sediment as environmental archive : natural and anthropogenic influence on the chronology of trace elements

    Author : Evastina Grahn; Stefan Karlsson; Anders Düker; Bo Bergbäck; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lake sediment; environmental pollution; trace elements; chronology; diagenesis; Ag; Be; Ga; In; Pb; Sb; Tl; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

    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
