Phytoremediation of Lead, Cadmium and Chromium Contaminated Soils using Selected Weed Plants
نویسنده
چکیده
Human activities like mining, transport, agriculture, industrial waste disposal and military actions release inorganic pollutants in high concentrations that are toxic to natural ecosystems. Heavy metal pollution causes potential ecological risk. Heavy metals like Cadmium (Cd), Lead (Pb) and Chromium (Cr) when present in high concentrations in soil exert potential toxic effects on overall growth and metabolism of plants and bioaccumulation of such toxic metals in the plant poses a risk to human and animal health. The phytoremediation is one of the promising biosolution for soil pollution. The earlier studies emphasized the need for selecting more and more species for reclamation of soil quality through phytoremediation. The present study is an attempt to test the potential of the native species to remove heavy metals from the soil. Abutilon indicum, Catharanthus roseus and Canna indica species were tested for their ability of phytoextraction of lead, cadmium and chromium from the contaminated soils. Bioconcentration factor and translocation factor was also calculated. The experiments revealed that Abutilon indicum was a good accumulator of chromium, Catharanthus roseus was good accumulator of lead and chromium and Canna indica was good accumulator of chromium. The plant species was recommended for phytoextraction of lead and chromium contaminated soils.
