The concentration of six trace factors, Fe, Cr, Co, Cu, Zn, Cd had been assessed in sediment samples of Ponnaiyar River, Gadilam River, Uppanar River, Vellar River, estuaries of Cuddalore District. Sediment samples collected from four locations of each estuary and elements were determined using Atomic Absorption Spectrophotometer (AAS). The parameter investigated were in the order of magnitude as by Fe>Cr>Co>Cu>Zn>Cd is existence range of trace metals in sediment samples. Among the studied heavy metals, Cd, Co, Cr, Cu, Fe, and Zn appear to reflect their background concentrations in sediments of Cuddalore estuaries. The most noteworthy groupings of Fe were found all through the sediments of estuaries by Fe>Cr>Co>Cu>Zn>Cd and the variation of metals in Gadilam River and Uppanar River is by modern wastage and un–characterized anthropogenic impacts. The consolidated waste materials, rapid urbanisation and agriculture practises aggravate the genuine hazard to the estuarine environment.
