Abstract: Zooplankton was sampled from Dandi creek -west coast of India (190, 48.041’N and 720, 41.255’E) on monthly basis from September 2009 to September 2010.Three stations were selected for collection of zooplankton, station 1 was in the open sea, station 2 was in the mouth of the creek and station 3 was in the creek. These stations covered an area of 12 km long and the depth varied from 2.7 to 25.5 meters (average 13.22 m). Five metals including Cadmium (Cd), Chromium (Cr), Lead (Pb), Mercury (Hg) and Arsenic (As) were analyzed in the zooplankton using Plasma Emission Spectrometer. Out of these five metals Arsenic (As) and Mercury (Hg) were not detected in zooplankton sample throughout the study period. The concentration of heavy metals shows variation in open sea, mouth of the creek and inner creek area .
