    Sammanfattning : Incineration of waste is increasing in the EU. However, in the incineration process, both fly and bottom ash materials are generated as waste that requires further action. A common goal throughout Europe is to find ways to utilize ash materials in an environmentally and economically efficient manner in accordance with the current legislation. LÄS MER

  3. 3. Vanadium in soils : chemistry and ecotoxicity

    Detta är en avhandling från ; Department of Soil and Environment, Swedish University of Agricultural Sciences

    Författare :Maja Larsson; Sveriges lantbruksuniversitet.; [2014]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Vanadium is a redox-sensitive metal that is released to soils by weathering and anthropogenic emissions. Swedish metallurgical slags are naturally high in vanadium and used as soil amendments and in road materials. However, understanding of vanadium chemistry and bioavailability in soils is limited.

  4. 4. From Science to Policy Improving environmental risk assessment andmanagement of chemicals

    Detta är en avhandling från ; Department of Soil and Environment, Swedish University of Agricultural Sciences

    Författare :Marlene Ågerstrand; Christina Rudén; Magnus Breitholtz; Misse Wester; Andreas Kortenkamp; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; environmental risk assessment; chemicals; pharmaceuticals; transparency; predictability; accuracy; consistency; voluntary initiatives; ecotoxicity data; reliability evaluation; relevance evaluation; non-standard test data; CSR; risk management.;

    Sammanfattning : A complex process like risk assessment and the subsequent risk management decision makingshould be regularly evaluated, in order to assess the need to improve its workings. In this thesisthree related matters are addressed: evaluation of environmental risk management strategies,evaluation of environmental risk assessments, and how ecotoxicity data from the open scientificliterature can be used in a systematic way in regulatory risk assessments.
