Sammanfattning : Arsenic (As) appears in the environment as various As species, which may vary in plant uptake and toxicity. Moreover, As exposure may vary between habitat due to availability and speciation, both of which are influenced by redox potential. To decrease As uptake, addition of silicate may be a tool. LÄS MER
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
Sammanfattning : The aim of the present study was to investigate the potential role of microbial accumulation in the mobility of metals in soil systems. As a first approach, the metal-accumulating properties of three bacterial species were studied to determine to what extent and under what conditions the accumulation occurred. LÄS MER
