%X 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¡À2.035 ¦Ìg mL-1 for Fe, 0.32¡À0.080 ¦Ìg mL-1 for Cu, 0.66¡À0.319 ¦Ìg mL-1 for Zn, 0.03¡À0.008 ¦Ìg mL-1 for Cd and 0.25¡À0.085 ¦Ìg 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.
