Abstract: Base line data on the metal concentration was obtained from three core sediments (S1, S2 and S3) of Manakudy e<translator wordrecognize="Stu" w:st="on">stuary on the south west coast of India. The acid leachable trace metals (Cr, Cu, Ni, Co, Pb, Zn and Cd) showed peak values at sulphidic phase . There is moderate level of pollution related to anthropogenic activities. The trace metals were associated with Fe and Mn indicating their adsorption onto Fe-Mn oxyhydroxides. The correlation of trace metals with sulphur indicates that they were precipitated as metal sulphides. Correlation m<translator wordrecognize="Atri" w:st="on">atrix showed elegant association between trace metals and Fe, Mn, S and mud.

The concentration factor was low (C<sub>f</sub><sup>i</sup> <1) indicating low contamination in the core samples. The anthropogenic factor (AF) values indicate moderate anthropogenic inputs. </translator></translator></translator>
