Abstract
A study is carried out to evaluate the heavy metals contamination in leafy vegetables in Navi Mumbai. Samples of four leafy vegetables—spinach, radish, mayalu, and red mat—were collected from Navi Mumbai. Heavy metals are determined in washed and unwashed bulk samples using a XRF spectrometer by the turbo quant-powder method. For visual identification of natural and anthropogenic particulates, geochemical, magnetic measurements, and scanning electron microscopy analysis of some washed and unwashed vegetable samples are carried out. The observed data when compared with the data of WHO limit, Fe, and Pb concentration were found to be more than permissible limits whereas the concentrations of Cu, Zn, Mn, and Ni were lower. Correlation coefficients between the magnetic susceptibility and concentrations of various elements in vegetable samples are computed. SEM images show the presence of a significant amount of magnetic spherules. Combined study of magnetic and chemical analyses provides informative results about shape, size, and surface structure of the particles contained in vegetables.
