| Résumé : | 1. Ten Greater Flamingos (Phaenicopterus ruber (Pallas)) and ten Little Egrets (Egretta garzetta (L.)) were collected in the Camargue (Rhône river delta), France. 2. High concentrations of cadmium and mercury were found in the liver and kidney of some individuals of both species. 3. Quantitation of metallothionein-like protein (MTLP) was performed using differential pulse polarographic analyses (DPP) on heat treated hepatic and renal cytosols. 4. In flamingos, correlations were established between copper and zinc levels, and MTLP levels in the liver, whereas copper, zinc, cadmium and mercury levels were correlated with MTLP levels in the kidney. 5. In egrets, zinc was the only metal correlated with MTLP levels in the liver. None of the metals were correlated with MTLP in the kidney. 6. Comparison of metal and corresponding MTLP levels showed that zinc was the most important metal influencing MTLP production in both organs of the two species examined. |
