The purpose of the study was to measure the physiological and cellular responses of Perna viridis after 1 and 2 weeks chronic exposure to copper (25 μg l−1) and mercury (25 μg l−1). Filtration rate, O:N ratio, scope for growth and growth efficiency of metal exposed mussels decreased significantly in comparison to controls. Digestive cells and tissues of metal-exposed mussels had severe pathological changes such as increased lipofuscin accumulation, digestive tubule dilation, tubule breakdown and cilia loss in the digestive diverticula. Compared to mercury, copper accumulated more in the tissues of exposed mussels. The physiological and cellular responses of mussels to copper and mercury were generally in the same direction, although mercury exposed mussels were comparatively less affected. Toxic effects of copper and mercury observed at cellular and tissue levels were found to be in agreement with those observed at the organismic level.
