“…The appearance of such an ultimate cellular disturbance is in agreement with the hypothesis of a n autolytic process, as a consequence of full lysosomal destabilization (Moore 1985). Necrosis and infiltration of severely damaged tubules by haemocytes have been reported by Rasmussen (1982) and Rasmussen et al (1983a, b) in mussels challenged with N-nitroso compounds. Couch (1985) described atrophic epithelium sloughing of cells and necrosis as a n ultimate tubular degeneration, in oysters from contaminated estuaries.…”

This comparative histopathological study, carried out at the GEEP Workshop, assesses tissue changes in mussels Mytilus edulis from a contaminated Norwegian fjord and from mesocosm basins where a contaminant gradient had been simulated. Parasitism by larval trematodes was observed in both circumstances, but was not related to contaminant levels. Mussels from the field exhibited granulocytomas in their interstitial tissues, with a greater incidence at polluted sites than at a reference site, suggesting that granulocytomas could be a consequence of chronic pollutant exposure. This pathological condition was not observed in experimentally treated mussels, which nevertheless had severe tissue alterations, especially in digestive tubules and gills, under exposure to high levels of a diesel oil and copper mixture. It is concluded that this type of histopathological analysis can provide useful information on the health of mussels, and that this information can be used successfully in the comparison of field samples.

The hazardous effect of water pollution on the histopathology of gill organ of the pearl oyster, Pinctada radiata was studied with respect to polycyclic aromatic hydrocarbon contamination in Al-Khiran coast at Kuwait. Thirty oyster samples from each site, site one where dead oysters were located, site two which is two kilometers away from site one and the control site which is ten kilometers away from site one were collected from Al-Khiran area where a massive number of dead oysters were reported. The gills of oysters were immediately removed and transferred to Bouin's solution for fixation and then processed for sectioning, staining and mounting and gill tissues were ready for examination. Histopathological changes in gills of oysters exposed to polycyclic aromatic hydrocarbons in site one and site two included necrosis and edemas of branchial lamellae, complete degeneration of gill filaments, loss of regular shape and haemolysis, and inflammation. Gill tissues of oysters from the control site had normal appearance. The study showed a clear evidence that PAHs caused severe histopathological changes in gills of pearl oyster Pinctada radiata.
