Investigations on Heavy Metal Uptake By Aloe Vera from Metal Contaminated Soils During Cultivation

Abstract

Studies were carried out to determine the levels of uptake of heavy metals viz. Pb, Cd, Zn, Fe, Cu, and Mn by fleshy leaves of Aloe vera Samples of Aloe vera plant. a plant of wide spread utility and medicinal importance. along with soil samples, were collected from fifteen different sites within and around industrial city of Kota, Rajasthan. Samples were processed, digested and then metals were determined by using Atomic Absorption Spectrophotometer. Correlation matrix has shown that most of the metal concentrations in plants and corresponding soil samples are significantly correlated.
