Abstract :

The trace elements in various tissues of different shrimp species, and in surface and bottom water sediments were analyzed using ICP–OES techniquethe possible roles of these trace elements in this regard are emphasized. Moreover, patterns of trace elements bioaccumulation and their order of occurrence have been evaluated. This paper also deals with comparison of the related data from different aquatic environments as well as existing guidelines and limits for human consumption. Comparison between the mean concentrations of the trace elements in Carapace, Gills, remaining body tissues and whole body tissues and in water samples are compared with existing guidelines, which indicate that the concentrations of K and Mg are well below the permissible levels for human consumption. However the concentrations of Li, Se,Sr, and TI were observed somewhat higher than the recommended levels. The amounts of Te present in different tissues of shrimps and in water samples are not comparable with that of the other aquatic animals, drinking water standards or with the human body because tellurium is not regarded as a true trace element, in that there is no recognized biological role for tellurium in human tissues and no clinical deficiency syndrome.
