Effects of Heavy Metals from Mine Water Drainage on Mudfish (Labeo capensis), Black Bass (Micropteris salmoides), Dam Sediments and Dolomitic Water in South Africa
The sediment in three dams of the Mooi River catchment,South Africa were analysed for cadmium,lead and copper.Fish tissue samples from a bottom feeder (Labeo capensis) and a predator (Micropteris salmoides) were also determined for heavy metal accumulation.Oxygen consumption rate ((M)O2) and operculum frequency decreased in both species exposed to different concentrations of cadmium,lead and copper.River and dam water from dolomitic origin complexes with lead and cadmium (but not copper) resulted in the precipitation of these toxic metals into the dam and river sediments,practically detoxifying the water column for lead and cadmium.
