  1. 11. Trace metal speciation in the Baltic sea

    Författare :Johan Gelting; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : Physicochemical speciation of metals in natural waters is very important for understanding their distribution, mobility, bioavailability and toxicity. To be able to understand the behaviour of an aqueous element and the transformation between chemical and physical species, there is a need for reliable methods that enable measurements of specific fractions of metals.

  7. 15. Cadmium Distribution and Speciation by Synchrotron Radiation Induced X-Ray Microprobe Techniques Application to Municipal Solid Waste and Biomass Fly Ashes

    Författare :Caterina Camerani Pinzani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; leaching; speciation; MSW; biomass; affinity; synchrotron radiation based micro-probe techniques; Ca-containing matrices; cadmium; fly ashes;

    Sammanfattning : During the last few years, alternative fuels, such as wood and Municipal Solid Waste (MSW), are increasingly being used in Sweden for heat and power production. The positive environmental impact in terms of low sulphur emissions, no net emission of CO2 to the atmosphere, and local availability are main driving forces in this development. LÄS MER
