Published in J. Nat. Resour. Life Sci. Educ. 33:51–53 (2004). http://www.JNRLSE.org © American Society of Agronomy 677 S. Segoe Rd., Madison, WI 53711 USA OVER THE PAST FEW DECADES, pollution has become a major threat to human and environmental health. Billions of acres of otherwise arable land lie uncultivated because of contaminants in the soil. However, remediation of contaminated land with conventional technologies is expensive as well as disruptive to the soil. Phytoremediation is an attractive alternative to remediate contaminated soil naturally and cost-effectively. This emerging technology uses green plants to remove organic pollutants, toxic heavy metals, or excess minerals from contaminated soil or water.

Role of Arbuscular Mycorrhizal (AM) Fungi in Phytoremediation of Soils Contaminated: A Review
Pollution of the soil environment with toxic materials from fossil burning, mining and smelting of metalliferous ores, disposal of sewage, fertilizers and pesticides, etc. has increased dramatically since the onset of industrial revolution. Application of plants with ability of absorbing heavy metals is a low-cost alternative for eliminating soils from heavy metals. Phytoremediation uses plants...

متن کاملAbility of some crops for phytoremediation of nickel and zinc heavy metals from contaminated soils
The present study was aimed at comparing the ability of three crop plants for phytoremediation of zinc (Zn) and nickel (Zn) from soils. A factorial (3×2×3) experiment based on RCBD was used to compare the treatments, and was repeated three times. The first factor was crop type (wheat, clover and rapeseed), the second factor was heavy metal types (zinc (Zn) and nickel (Ni)) and the third factor ...

The objective in the first phase of this study was to screen alfalfa, flatpea, sericea lespedeza, deertongue, reed canarygrass, switchgrass, and tall fescue for phytoremediation of polychlorinated biphenyl (PCB)-contaminated soil. During the second phase, the focus was rhizosphere characterization to optimize PCB phytoremediation. Aroclor 1248 (PCB) was added to soil at 100 mg x kg(-1) of soil....
متن کاملThe Potential of Chrysanthemum and Pelargonium for Phytoextraction of Lead - Contaminated Soils
Phytoremediation is a set of technologies that uses plants to clean up contaminated soils and groundwater. Phytoremediation is environmentally friendly, successful and cost-effective compared to other in situ methods such as the electrokinetic method. In this work, two local plant species, Chrysanthemum and Pelargonium, were examined for their ability to uptake lead from lead contaminated soils...
