Abstract

The ultrastructural studies by transmission electron microscopy revealed significant changes at cellular level in both digestive
gland and digestive tract of Perna viridis collected from polluted water near the coast as compared to those collected 1 km off
the shore line. The digestive gland cells of polluted group showed distorted and enlarged nuclei along with several inclusions
and lipid granules in the cytoplasm. The cells lining the digestive tract also revealed the presence of large number of lipid
granules, inclusions, vacuoles, disturbed epithelium along with lytic areas, necrosis and enlarged nucleus. The morphological
changes in the digestive cells of mussels are attributed to environmental stress i.e., due to the sequestration of heavy metal
pollutants in the specimens collected from the coast. The damage to tissues at cellular level has been discussed in the light of
previous reports and observations which employed green mussels as biomonitors of marine pollution.
