Heavy metal concentrations in sediments and Cyprinus carpio from Maqalika Reservoir -Maseru, Lesotho: An analysis of potential health risks to Fish consumers.

ABSTRACT: The determination of heavy metal contaminants in fish is very important in monitoring health risks to humans who consume them. This study assessed the concentration of heavy metals (As, Pb and Zn) in sediments and gills of Common Carp fish (Cyprinus carpio) from Maqalika Reservoir in Maseru, Lesotho and their potential health risks to such fish consumers. Sediment and Cyprinus carpio samples were collected from upstream, midstream and downstream sites of Maqalika Reservoir and examined for As, Pb and Zn using atomic absorption spectrometer. Potential health risks were based on comparing the derived metal concentrations in gills of Cyprinus carpio with the World Health Organization (WHO) permissible limits for human consumption. The mean concentration levels of Zn, As and Pb in sediment wer
