Water pollution bas increased in heavy industrialised areas. Most industrial water wastes end up in the sea. Monitoring the elemental composition in marine organisms, such as snails, provides the essential elements in living organisms and through the food chain to man. 50 samples of each of two kinds of snails have been collected from the west coast of Libya. Samples were digeste with nitric acid and the concentration of Copper, Iron, Magnesium and Zinc were determined by atomic absorption spectrometry. The results shows that Mg has the highest value while the Copper has the lowest in both kind of snaiis. A pattern of the trace elements concentration was investigated regarding the size and kind of snails.
