Lamellidens consobrinus were intoxicated with CrO3 and then analyzed for histo-pathological changes in digestive glands. Many digestive tubules were damaged the inter-tubular spaces. The digestive cells were separated leading to tubular atrophy, as a result of which endo-cellular digestion, absorption and detoxification was adversely affected. The histopathological changes suggested that the mussels give can be used as markers for studies on heavy metal pollution in freshwater ecosystem.
