Resumo: 	In this study, zinc (Zn), cadmium (Cd), lead (Pb), phosphorus (P) and calcium (Ca) concentrations in muscle, gills, liver, gonads and skeleton of two naturals populations of sand smelt Atherina lagunae (Teleostean, Atherinidae) normal and deformed, as well as bioaccumulation of these elements from the water and the sediment in the North Tunis Lake were investigated. The analysis of calcium was performed with flame atomic absorption spectrometry. The average concentrations of Ca in the different tissues analyzed show higher values in healthy atherines except in gonads where the average concentration of Ca in deformed atherines significantlyexceeds that in normal atherines (p &lt;0.05) and the Ca spine concentrations where the similar in the two populations. Zinc, cadmium, lead and phosphorus were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). The Zn concentrations of Atherina lagunae in North Tunis Lake were very high compared to other studies in other lagoons. The highest concentrations were found in deformed atherines. The differences are significant for all tissues studied (p&lt;0.05). The average concentration of P in different tissues analyzed shows that the highest values were detected in the normal population of Atherina lagunae. The potential rate of Cd was below the limit detection in the different organs analyzed, in water and sediment.
