Sequestration and remediation of heavy metals by Brassica sp at Hindan river sites

摘要

Various kinds of industries have grown up in and around city Ghaziabad(Sahibabad industrial area).The river Hindan is the principal sink of industrial effluents and agricultural wastewater.Industries discharge effluents directly into the river Hindan.The pollution is widespread but varies in its intensity and toxicity from place to place.The analyses and monitoring of some plants grown with water contaminated with industrial effluent revealed the accumulation pattern of various heavy metals like Hg~2+,Cd~2+,Pb~2+,Ni~2+and Zn~2+in different plants.Among the plants tested only Brassica juncea has potential to withstand contaminated river samples as it has means to sequester toxic metals in specific compartments.
