   Sammanfattning : In the present thesis the phylogeny and patterns of genetic diversity of the plant genus Alisma (Alismataceae) were investigated by means of genetic markers (RAPDs, allozymes, and ITS and trnL sequences). Additionally, morphological studies were carried out in paper IV. LÄS MER

3. 2. Metal accumulation by plants : evaluation of the use of plants in stormwater treatment

   Sammanfattning : Metal contaminated stormwater, i.e. surface runoff in urban areas, can be treated in percolation systems, ponds, or wetlands to prevent the release of metals into receiving waters. Plants in such systems can, for example, attenuate water flow, bind sediment, and directly accumulate metals. LÄS MER
