Heavy metal accumulation by plant species from a coal mining area in Orissa.
An ecological survey was undertaken on metal contamination (Cu, Fe, Al, Cr) of vegetation (tree, shrub and herb) collected from the overburden soil of South Bolanda, Talcher, Orissa. Stem and leaf parts of the trees and shrubs, and whole plant of the herbs were analysed. Concentrations of metals were the maximum in leafy part of trees and shrub samples. Among the various heavy metals studied, Fe concentration in plant parts was the highest and Cu concentration was the lowest.
