Bio-akkumulering van metale in organe en weefsels van die platanna Xenopus laevis in myn- en nywerheidsbesoedelde varswaterekosisteme

- Description: M.Sc. (Zoology) , An investigation was made into the presence and uptake of seven selected metals by the organs and tissues of the various developmental stages of the African clawed frog Xenopus laevis from industrial, mine and sewerage polluted aquatic environments on the Witwatersrand. These results were compared with conditions in two relatively unpolluted localities where the clawed frog also occurs. Attention was given to the physical and chemical conditions including the concentration of the metals at various localities. Gut content analyses of the frog stages of the plataona was made to identify the particular food items ingested by the animal but also to correlate this with the incidence of the macro invertebrate organisms present. Metal concentrations were determined for both the gut contents as well as the macro invertebrates as a group at two selected localities. The presence and concentration of various metals were determined in specific organs and tissues of the frog and compared with each other. According to the data the spleen, gallbladder, middle & Hind gut as well as the testes were identified as the target organs containing the highest concentrations of the various metals. Shortcomings in the work is pointed out and recommendations made on possible further research.
