Abstract
Plants provide us food, fibre, wood, cosmetics etc. Phytoremediation
technology is the use of green plants to remediate heavy metals, contaminants
from soil, air, water and environment. Anthropogenic activities, industries,
household activities make water, soil impure. Water, Soil near industries and
mining are more impure as compared to planted areas. Plants that removes heavy
metals are Solanum lycopersicon, Helianthus annus, Eicchornea crassipes,
Brassica juncea, B. nigra etc. Heavy metal remediation is higher where
plants are there. Aloe vera, bamboo, Chrysanthemum, Azadirechta
indica, etc plants as well as trees purifies air. Phytoremediation
technology consists of processes and Mechanisms to remediate heavy metals and
other contaminants. Phytofiltration-Accumulation of pollutants, heavy metals in
harvestable biomass ie shoots. Phytostabilization-Limiting the quality and
bioavailability of pollutants in soil by plant roots. Phytovolatalization-Conversion
of pollutants to volatile kind and their succeeding biomass to the atmosphere
eg by transpiration. Phytodegradation-Degradation of organic pollutants or
compounds by plant enzymes among plant tissues. Rhizofiltration- By roots. Rhizodegradation-Degradation
of organic compounds within the rhizosphere by rhizospheric microorganisms. Phytodesalination-Remediation
of excess salt from saline soils by halophytes. Phytofiltration-Sequestration
of pollutants heavy metals from contaminated water by plants. Phytomining-Production
of a metal by growing high biomass plants that accumulate high metal
concentrations, a number of these plants are natural hyperaccumulator's.
