| Abstract | ||
| Destruction of spleen and kidney components in C. idella started on the 17th day in specimens subjected to 20 µg•L-1 Cd . The spleen was actually destructed after 73 days of exposure to 60 µg•L-1 Cd , where the two pulps can not be distinguished clearly, as the splenic blood vessels contained less blood cells . The kidney showed a complete destruction and the hematopoietic tissue lacked a distinguishable border whereas the necrosis covered large area after 60 days at 60 µg•L-1Cd . The degree of destruction was lineary proportional to concentration of toxicant and period of exposure although the period was somewhat more effective . It was concluded that the histological alterations in spleen and kidney could be used as an indicator for water pollution with cadmium and for fish health as well . | ||
