| Summary: | To assess contamination levels of the heavy metals, concentrations of Sc, Cr, Fe, Co and Zn in surface soils
at various locations of southern part of Bangladesh were determined by Instrumental Neutron Activation Analysis
(INAA) technique. In this study, concentrations of the Sc, Cr, Fe, Co and Zn elements in surface soil were found in
the range of 2.56-16.7 μg/g, 12.9-112 μg/g, 6911-48642 μg/g, 2.59-22.7 μg/g and 37.7-322 μg/g, respectively. The
measured concentrations were compared with average concentration of worldwide soil and observed that most of
the samples contain much higher concentration of heavy metals except Cr and Fe. Analysis based on soil utilization
type showed that the samples collected from roadside and residential area experienced much higher metal
contamination than open area. A significant correlation was observed between Cr-Fe, Cr-Co, Cr-Sc, Fe-Co, Fe-Sc
and Co-Sc. |
