2. 1. Mercury immobilization : a requirement for permanent disposal of mercury waste in Sweden

   Author : Margareta Svensson; Bert Allard; Anders Düker; Björn Öhlander; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; mercury; mercury sulphide; cinnabar; stabilization; solidification; encapsulation; monolith leaching; solubility; mercury speciation; diffusion; apparent diffusion coefficient; Chemistry; Kemi; Enviromental Science; Miljövetenskap;

   Abstract : The Swedish Government states that mercury in the Swedish industry and private use shall be collected and waste containing more than 1% of mercury shall be conditioned for permanent storage in proposed groundwater-saturated repository in deep bedrock. The owners of mercury waste in Sweden are responsible for finding ways to the conversion of the mercury waste to insoluble forms. READ MORE

4. 2. Catching Mercury : Mercury in Lake Vänern and Swedish catchments

   Author : Peter Wihlborg; Lars Hylander; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; mercury; deposition; budget; sediments; retention; catchments; dating; kvicksilver; deposition; budget; retention; avrinningsområden; datering; Water in nature and society; Vatten i natur och samhälle;

   Abstract : Vänern och dess sediment har under 1900-talet varit en av Sveriges mest kvicksilver (Hg) kontaminerade miljöer. 47 sedimentprofiler tagna 2001 analyserades for total Hg och temporala och spatiala mönster påvisades. Av den direkta Hg tillförseln 1918-2001 återfinns c:a 30 ton i bottensedimenten. READ MORE

5. 3. Mercury-induced autoimmunity : Genetics and immunoregulation

   Author : Monika Hansson; Manuchehr Abedi-Valugerdi; Marita Troye-Blomberg; Lucette Pelletier; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mercury; autoimmunity; collagen-induced arthritis; Th1 Th2; silver; tight-skin 1 mice; Immunology; Immunologi;

   Abstract : The existence of immune self-tolerance allows the immune system to mount responses against infectious agents, but not against self-molecular constitutes. Although self-tolerance is a robust phenomenon, in some individuals as well as in experimental models, the self-tolerance breaks down and as a result, a self-destructive autoimmune disease emerges.

6. 4. Transport of Mercury Species in the Environment. Exchange between Oceanic Waters and the Atmosphere

   Author : Maria Andersson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mercury; dissolved gaseous mercury; elemental mercury; evasion; flux; Mediterranean Sea; North Atlantic Ocean; Arctic Ocean; accumulation; in-situ measurements; on-line measurements;

   Abstract : Mercury is an element present in the earth crust as well as a component in the atmosphere. During centuries mercury has been released by natural sources, e.g. volcanic eruptions, evasion from water surfaces and degassing from soil. READ MORE

7. 5. Remediation of mercury polluted soil

   Author : Thomas Lifvergren; Bert Allard; Örebro universitet; []
   Keywords : soil pollution; soil remediaion; mercury; NATURAL SCIENCES; NATURVETENSKAP; Enviromental Science; Miljövetenskap;

   Abstract : Mercury in contaminated soil constitutes a wide spectrum of species with highly different properties due to the chemical complexity of the element. Assessments of risk, ecological effects and removal potential require process and mobility studies. READ MORE
