Abstract
Now a days, Phytoremediation is treated as a set of emerging techniques that use several selected plants to contain, eradicate, immobilize or degrade contaminants from water and soil in order to clean the contaminated sites. Recent researches have directed to the application of non-edible floriculture plants having the capability to erase the toxic metals from polluted environment including their aesthetic value as a good proposal for phytoremediation. The plant Tagetes erecta Linn., locally recognized as Ganda Phul (Marigold) that belongs to the family of Asteraceae can grow widely in heavy metal stress of Cd, Cr, Pb etc. The plant species can absorb and accumulate varieties of contaminated heavy metals like Pb, Cr, As, Cd, Co, Hg etc. This article includes a brief overview about the toxic impact of the Cr, Cd, and Pb on the plant. In addition, the discussion highlights recent progress on the application of phytoremediation competence of the plant, Tagetes erecta Linn. concerning with the heavy metals.
