Abstract: The present investigation has been conducted to examine the surface water and sediment quality especially some selected heavy metals of Noakhali canal adjacent to Bangladesh Small Cottage and Industries Corporation (BSCIC), Begumganj, Noakhali, Bangladesh. The concentrations of heavy metals in water and sediment have been analyzed by means of Flame Atomic Absorption Spectrophotometer (FAAS). The mean values of pH, EC, TDS, P, K, SO42-, Cl-, NaCl and Temperature in surface water were 6.744, 1302μS/cm, 634.9mg/L, 0.0835mg/L, 0.466cmol+, 2.978mg/L, 328.289mg/L, 2.46mg/L and 26.84 0C, respectively. The average concentration of Fe and Mn in surface water was 0.55mg/ L and 0.4081mg/L and the rest of heavy metals were found below detection limit. The mean values of pH, EC, OC, OM, TN, P, K, S in sediment sampling sites were 6.83, 565.5, 2.427, 4.185, 0.21, 43.1μg/g, 0.5 meq/100gm, 157μg/g, respectively. The order of heavy metals in sediment was Fe Mn Zn PbCu. Almost all water and sediment quality parameters and heavy metals were within acceptable limit prescribed by national and international standards except Fe, EC, OC, OM, S, P and K. According to Sediment Quality Guideline, sediment samples were not polluted for Pb, Cu, Mn, and Zn. The geo-accumulation index (Igeo) showed no pollution for most of the sampling sites for all studied heavy metals except Fe.
