Air pollution irrespective of their source of origin tends to
increase in atmosphere. Various air pollutants include volatile
organic compounds, particulate matter, and other persistent organic
pollutants. These pollutants pose various health hazards on human
beings including cancer. It has been prominently recognized to cause
burden on eco-system and human well-being. However, some remediation
techniques are available in the market yet their high maintenance
cost, lesser durability, and complex principals make them an
inappropriate option for air pollution control. Phytoremediation
enters as a cost-effective, low-maintenance, eco-friendly, and
energy-saving option. Phytoremediation involves different plant
organs for absorption and decomposition of pollutants. The review
presents an overview of the existing technologies of
phytoremediation. Furthermore, it highlights the loopholes in the
technologies which may be useful for the researchers in the field to
present more promising and effective work in near future. |
