South Africa stands out as a prominent global contributor of mercury (Hg) emissions, matter great concern due to its toxic nature and potential serious health effects on biota if it enters the environment. Mercury freshwater systems through various anthropogenic activities, such emissions from coal-fired power stations artisanal gold mining. Studies have indicated that bivalves accumulate metals their aquatic The bivalve genus Corbicula is widely distributed across relatively abundant. Given widespread presence clams in Africa, they serve bioindicators for Hg pollution ecosystems. A total 34 sites were sampled northeastern part with found at 15 these sites. At each site, minimum five collected, alongside water sediment samples. Total (THg) concentrations determined clam samples using flow injection system. correlated different land-use where closer sources had higher THg concentrations. This study also environmental Olifants, Inkomati Water Management Areas reported 12 years ago. Clam be than corresponding samples, specifically larger clams, suggesting longer exposure some weak positive correlation was between concentrations, suggested bioaccumulation may influenced more by period, rather highlights effective since accumulation tissue can provide better overview bioavailable system, compared abiotic alone.
