| Abstract | The paper attempts to identify the enrichment pattern of acid leachable trace metals (ALTMs) such as Fe, Mn, Cr, Cu, Ni, Pb, Cd, Co, Ag and As and their relationship with sediment quality parameters (pH, organic carbon and texture) in core sediments (<63;m parti cle size) from Indian Sunderban mangrove wetland, India. The results indicate that the change in pH values causes coagulation and precipitation of ALTMs. Fe and Mn have fairly close distribution patterns of enrichment in surface layers which might be ascribed to early diagnetic processes. The most prominent feature of ALTMs is the enrichment of Fe, Mn, Cr, Cu, Ni and Pb in the surface=subsurface layers in the sedi ment cores, which is mainly attributed to the intense industrial and agricultural activities as well as drainage of domestic sewage to this coastal region. The ALTMs also indicate their association with organic carbon and Fe=Mn oxyhydroxides. The enrichment is well= supported by the correlation, grouping and cl ustering of ALTMs in statistical analyses. Anthropogenic Factor (AF) values indicated ALTMs enrichment for all heavy metals due to intense anthropogenic activities. The result suggests the urgent need for phytoremediation using mangrove plants as remediation strategy to decontaminate the sediments contaminated with inorganic contaminants. |
