Application of the dry and wet biomass of bryophytes for phytoremediation of metals: Batch experiments

The environmental contamination by metals is a concerning problem, especially when considering the characteristics of bioaccumulation and biomagnification of these elements. Once present in the water, metals are easily accrued by organisms and they can reach superiors trophic levels, including human...
