   Nyckelord :acid sulfate soil; hydrological drought; water chemistry; metal leaching; sulfate concentration; sur sulfatjord; hydrologisk torka; vattenkemi; metallurlakning; sulfatkoncentration;

   Sammanfattning : Sediments rich in sulfide were deposited in the Littorina sea in an environment that was shallow, anoxic,and reductive. The sediments were brought above sea level by isostatic uplift and can now be foundalong the coast of the Baltic sea. LÄS MER

   Sammanfattning : Acid Sulfate soils (AS) are recognized for being a source of acidity in freshwaters in America, Europe, Australia, and Asia. Apart from the problematic acid leachate, AS soil serves as a possible source of toxic heavy metals in freshwaters, a problem which has received far less attention than problems related to acid leachate.
