Abstract:
The purpose of this study was to provide baseline data on the mineral status of impala and to
investigate the possibility of using impala as sentinel species for monitoring important elements
that may affect livestock and wildlife production in southern Africa. Approximately 27 impala
were sampled at the Messina Experimental Farm. Animals of different sexes, age groups and
anatomical locations were sampled. Specific tissues sampled were: liver, thyroid gland, kidney
fat and kidney and approximately 100g of each tissue was collected.
The study examines direct cause and effect by taking a holistic approach, which includes
examining exposures according to age, sex and body burden. In order to review and summarize
the health state of sampled areas in terms of exposure to environmental heavy metal
contaminants. Impala (Aepyceros melampus) were used as indicator species in this study.
