[Toxicity of lead nitrate to the carp (Cyprinus carpio L.). Effect on respiratory metabolism and histological structure of gill lamellae (author's transl)].
Oxygen uptake of gills was estimated after lead poisoning of the Carp. Histological structure of gill lamellae was also examined. Oxygen uptake quickly decreased after two weeks then increased again in long term poisoning without total recovery. On the other hand, desquamation of the gill epithelium was observed as well as proliferation of mast cells probably loaded with lead. The return to clean water for eleven weeks, allowed the lamellar epithelium recovery but not the mast cells elimination.
