Heavy metal (Cu, Zn, Cd, Pb and Fe) concentrations in salt marsh sediments of the Karnafully River coast were investigated this study. Sediment samples four different sites analysed for selected heavy metals by AAS (atomic absorption spectrophotometry). The mean values 45.79 µg/g Cu, 105.0 0.43 26.70 3297.38 Fe It is observed that Cu have positive correlations (r = 0.370, P < 0.05) Zn negative -0.729, correlation matrix. Except Fe, all found at contamination levels which may indicate a recent continuous from domestic industrial discharges. results sediment showed facing pollution.
