Abstract :

The toxic elements such as Al, B, Ba , Be, Bi, Ca, Cr, Ga, K, Li, Mg, Se, Te, and Ti are potentially harmful and caused toxic effects to most organisms even in very low concentrations. The research paper is focused on distribution of trace elements in various tissues of different species of shrimps, and in surface and bottom water sediments. The 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. Another part of this paper 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 indicate that the concentrations of Al, Ba, Ca, Cr, K and Mg are well below the permissible levels for human consumption. However the concentrations of Be, Bi, Li, Se, Sr, TI were observed somewhat greater than some of the recommended levels and cited literature. The amount of B, Ga and 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 there are no such guidelines.
