The present study have been conducted to evaluate the status of heavy metals (Pb, Cd, Ni, Cr, Cu, Zn, Mn, As, and Sb) in the surface water and bed sediment samples collected from nearby southern region, Bangladesh. Heavy metals pollution status in sediment was analyzed using Atomic Adsorption Spectrophotometer. The mean concentrations of analyzed heavy metal in the water ranking sequence of: Zn > Cu > Mn > Cr > Sb > Ni > As > Pb > Cd and in the sediment ranking sequence of: Mn > Zn > Ni > Cr > Cu > Pb > As > Sb > Cd (mg/kg). As a part of findings, the water from southern region considered as polluted with respect to different water quality guidelines and sediment considered as unpolluted with respect to different sediment quality guidelines. The contamination factor (CF) result indicated that sediment were contaminated and Geo-accumulation index (Igeo) result indicated the sediment moderately contaminated to high degree of contaminated except Mn and Cr. PLI values indicated that all site was polluted.
