Ostracods form an important part of benthic biota. They form a feed to many fish, insects, insect larvae and even corals. In the vast aquatic biome both freshwater and sea they occupy an important place in the food chain. Experiments were conducted on a freshwater ostracod species, Chrissia halyi, culturing them in the laboratory along with chlodophora the feed. The feed was first exposed to lead at different concentrations and fed to ostracods. The results showed significant amount of accumulation even for 4 days. There was a good increase in accumulation in 1, 2 and 3 ppm from 24 hrs to 96 hrs but in 4 ppm the accumulation was constant. The results are discussed.
