Description 102-105
Geochemical
associations of some trace metals (Fe, Mn, Co, Zn, Cu, Cr, Ni and Pb) along the
Bahuda indicate insignificant aerial difference in the total trace metal
concentrations. Exchangeable fraction constitutes an extremely low

percentage of total non
lithogenous material. The higher availability of Mn compared to Fe in
exchangeable fraction is observed. Association of heavy metals (except Mn, Zn
and Co) in carbonate phase appears to be the least dominant phase in the non
lithogenous fraction. Fe-Mn oxides-bound fraction is the dominant phase among
non-lithogenous with high scavenging capacity for metal ions like Fe, Mn, Ni
and Cr. Organic phase is found to be an efficient scavenger of heavy metals
followed by Fc-Mn oxide fraction.
