A study was carried out in the Mumbai Harbour Bay sediment cores to measure concentration of biologically significant toxic elements such as Cr, Cu, Co, Ni, and Pb and to find out pattern of distribution in the sediment bed to follow the accumulation of elements with respect to depth. The range of concentration values of Cr, Cu, Co, Ni, and Pb in the sediment core fractions collected from three locations from Mumbai Harbour Bay sediment versus depth were plotted. Among the five elements, the concentration of Cr and Ni was found to be comparatively higher than all other elements with a range of 36 to 483 ppm and 24 to 155 ppm, respectively. The concentration of Co and Pb was observed to be lower in all the sediment cores and also evenly distributed in all the fractions with a range of 12-40 ppm and 10-270 ppm, respectively. Cu showed a range of 5-300 ppm.
