    Sammanfattning : The amount of municipal solid waste incineration (MSWI) fly ash has increased in many parts of the world in recent years. Ashes from municipal solid waste incineration (MSWI) may be a cumbersome waste to handle since containing significant amounts of leachable hazardous metal species and must be landfilled in special sites at high costs.

    Sammanfattning : Air pollution with particulate matter (PM) raises considerable concern because of its adverse effects on human health. For this reason, and because the mechanisms of PM toxicity are not fully known, there is an urgent need to determine the chemical constituents of atmospheric PM, especially PM emanating from traffic - a major source of urban PM.
