    Sammanfattning : This dissertation in the history of science and ideas studies the Swedish dental amalgam controversy in the late 20th century. Erupting in the early 1980s, the controversy concerned the issue of whether mercury containing dental amalgams could poison those who had had their teeth filled, or whether the many patients making such claims were in fact suffering from stress, unresolved trauma, or other illnesses.

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

    Författare :Peter Wihlborg; Lars Hylander; Linköpings universitet; []
    Nyckelord :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;

    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

  4. 3. Seasonal Cycling of Mercury in the Antarctic Sea Ice Environment

    Författare :Michelle Nerentorp; Chalmers tekniska högskola; []

    Sammanfattning : Mercury is a globally distributed contaminant that exists in the atmosphere as a stable monoatomic gas. Having almost a year’s residence time in the air allows it to reach remote polar regions. Deposited airborne mercury can be transformed in the environment to the organic and bio-accumulating compound methyl mercury. LÄS MER
