remedium definition
remedium derived from Latin means ‘able to cure’ or ‘restore’ (Vamerali et al., 2010). Phytoremediation is used to remediate a variety of organic (Cluis, 2004) and inorganic contaminants (Vamerali et al., 2010). This technology can be applied to both organic and inorganic pollutants present in soil (solid substrate), water (liquid substrate) or the air (Salt et al., 1998). In this respect, plants can be compared to solar driven pumps which can extract and concentrate certain elements from their environment (Salt et al., 1995). However, the ability to accumulate heavy metals varies significantly between species and between cultivars within a species.
