Sammanfattning : 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. LÄS MER
Sammanfattning : 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. LÄS MER
Sammanfattning : 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.

4. Transport of Mercury Species in the Environment. Exchange between Oceanic Waters and the Atmosphere
Sammanfattning : 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. LÄS MER
Sammanfattning : 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. LÄS MER
