Analysis of Heavy metals (Nickel, Chromium, Cobalt, Cadmium, Lead) in Wheat and Rice grown in agriculture soil

Abstract

The objective of present study is to evaluate how the five heavy metals nickel, chromium, cobalt, cadmium, and lead are move from soil to rice and wheat, two important Indian crops in terms of nutrition, grown in agriculture soil. Between April and November 2021, soil samples from the research region were taken. With the aid of a flame atomic absorption spectrophotometer, the presence of heavy metals in the soil was discovered. The agricultural soil's mean concentration of heavy metals (mg kg-1) was distributed in the following order: Ni (9.34 ± 0.348) > Pb (8.50 ± 0.42) > Co (7.43 ± 0.28) > Cd (4.07 ± 0.186) > Cr (0.135 ± 0.028) respectively. According to Indian norms, the average level of all examined heavy metals in agricultural soil was below allowable levels.
