“…They are of interest with respect to the bioremediation method called phytoremediation, 110,111 in which plants are used to sequester or modify an environmental contaminant, thereby alleviating an environmental problem without the need for excavating large amounts of soil or rock. The levels of accumulation can be quite extreme; for example, the New Caledonian tree Sebertia acuminata can have vivid blue-green latex due to its startlingly high nickel concentration of about 2 M. 112,113 Other examples include the nickel hyperaccumulating penny-cress Thlaspi goesingense , 114,115 the arsenic hyperaccumulating brake fern Pteris vitata , 28,60,61,116 and the selenium hyperaccumulating two-grooved milk vetch Astragalus bisulcatus .…”

“…For phytoremediation many alternate strategies can be used. The cultivation of ornamental plants, floriculture crops, tree plantations and growing of aromatic grasses was used to remediate soil 38 . However, this method is not widely accepted because of the issue of pollution transfer from soil to plant and heavy metal content in biomass 39 .…”

One of the major problems, that the world is facing today due to rapid industrialization is environmental pollution caused by several factors, including heavy metals. Among the heavy metals, cadmium is a hazardous carcinogenic element. From contaminated soil, cadmium enters the plants through the roots and is accumulated in the harvestable (edible) parts, and thus gains entry into the food cycle. Phytoremediation plays a beneficial role in the remediation of cadmium contamination from soil, but becomes less effective with increasing toxicity. Even hyperaccumulator plants fail to perform under these conditions. Plant growth promoting rhizobacteria (PGPR), inhabitants of the plant rhizosphere, play a supporting role and promote bioremediation of soil by accumulation or transformation of contaminants, thereby enhancing plant growth and development. This article focuses on cadmium contamination and PGPR-assisted phytoremediation of cadmium-contaminated soils.

“…Moreover, their growth is supported due to porous nature of FA which assists better root growth. The unpalatability, minimal water requirement and perennial nature of these grasses make them more suitable to be used in restoration studies (Gupta et al, 2013).…”

Abstract. Uninterrupted generation of fly ash by the coal based thermal power plants and its dumping has lead to steady encroachment of useful land in India. The deleterious effects of fly ash on the nearby environment are inevitable due to its fine texture and presence of toxic metals. Thus, proper revegetation programme of the sites are highly desirable due to their continuance in being the part of landscape. This paper conglomerates all the issues which should be taken into account to prevent groundwater contamination and increase phytostabilization of metals. An insight to the past and the prevailing restoration scenario will help in selecting of plant species for biomass production. Primarily, an integrated approach towards revegetation is necessary which comprises native and exotic grass-legume species, readily available composts, green manure, and mulches. The paucity of studies in relation to the long term changes in fly ash due to vegetation is to be permeated through regular analysis of substrate nutrient status, extent of nutrient loss, bioavailable toxic metals, in restoration sites. The range of methodologies and indexes discussed here will benefit the future management approaches of fly ash with emphasis on phytoremediation of trace metals, development of aesthetically pleasant landscape and productivity.
