Heavy Metal Concentration in Pore Water of Salt Marsh along the Karnafully River Coast, Bangladesh

M.A.M. Siddique and M. Aktar

Abstract: Heavy metal concentrations (Fe, Cu, Zn, Cd and Pb) in salt marsh pore water of Karnafully River coast were investigated in this study. Water samples of four different locations were analyzed for selected heavy metals by AAS (Atomic Absorption Spectrophotometry). The mean values of heavy metals were recorded 4.63±2.035 μg mL^-1 for Fe, 0.32±0.080 μg mL^-1 for Cu, 0.66±0.319 μg mL^-1 for Zn, 0.03±0.008 μg mL^-1 for Cd and 0.25±0.085 μg mL^-1 for Pb in this study. It is also observed that Cd is found to positively correlate with NO₂-N (r = 0.957, p<0.05) and Zn (r = 0.970, p<0.05). However, positive correlations were also found between Cu and Fe (r = 0.985, p<0.05) and Cu and Zn (r = 0.959, p<0.05) in salt marsh pore water. The mean concentration of Fe, Cd and Pb were found above the recommended value which may indicate a fresh and continuous contamination of salt marsh pore water due to anthropogenic activities.
