Study of fractionation, mobility and risk assessment of selected metals in suburban, urban and roadside soil from Pakistan

This study was carried out to elucidate the chemical fractionation pattern of selected metals (Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Pb, Sr and Zn) in the soil collected from roadside, urban and suburban environment. Modified sequential extraction method was applied to assess the exchangeable, reducible, oxidisable and residual fractions of the metals in soil samples. Quantification of the metals was performed by atomic absorption spectrometry....
