Abstract
Samples were collected low tide period from ten points in three seasons such as the pre- monsoon (November- February), monsoon (March–June) and post-monsoon (July–October), during 2015-2016. Samples were analyzed for finding of some metals concentration such as Na, K, Ca, Mg, Fe, Pb, Cu, Zn, Cd, As, Cr and Mn. The mean value was reported for each parameter. The investigated parameters were compared to national and international Standard. The concentration of some metals such as Na, K, Ca, Mg, Fe, Pb, Cu, Zn, Cd, As, Cr and Mn were found to be 327.24 ppm, 24.65 ppm, 29.42 ppm, 44.35 ppm, 15.28 ppm, 15.52 ppb, 0.018 ppm, 0.072 ppm, 0.066 ppm, <0.05 ppm, 0.62 ppm & 0.355 ppm respectively. The heavy metal pollution index (HPI) was found to be 1479.89 which was upper of the critical index limit of 100 and also indicates unsuitable for Drinking.
