A review on feasibility of phytoremediation technology for heavy metals removal

Abstract

Quick jump of urbanization and industrialization is responsible for birth of heavy metal pollution. In the aquatic systems, heavy metals are one of the most dangerous pollutants that may be found. It can have both natural and anthropogenic origins. In aquatic ecosystem heavy metal pollution have a serious hazard to biodiversity of aquatic ecosystems, and drinking polluted water contaminated with heavy metals can have severe health risks in humans as well as in all living-beings. The commercial characteristics and side effects of conservative treatment equipment in aquatic environment flagged the way to eco-sustainable technology like phytoremediation. In phytoremediation, Plants are used to clean up the environment from numerous dangerous contaminants. Phytoremediation is cost-effective and ecofriendly expertise for environmentally friendly cleanup. The present review reflects the characteristics of heavy metals and possible environmental threats together with this, review also inspects the role played by the macrophytes in phytoremediation studies in the recent past. In the reduction of heavy metal contamination in aquatic environments which receive the industrial discharges and municipal wastewater, aquatic macrophytes are powerful tools to remediate them.
