摘要：

Uranium (U) levels in drinking water sources in the vicinity of a U mine in the Siavonga district in the Southern Province of Zambia are alarming. The median U concentrations in drinking water sources showed a decreasing trend: streams (135.30 mu g/L) > dams (115.62 mu g/L) > boreholes (111.31 mu g/L) > shallow wells (110.03 mu g/L). The U levels in all the samples exceeded the safe limit for drinking water recommended by the World Health Organization, suggesting that the water is not safe for consumption. The mean target hazard quotients (THQ) in all of the water samples exceeded the safe limit (THQ > 1), implying that consumers of this water were at a greater risk of potential non-carcinogenic health effects. The carcinogenic risks from uranium at most of the drinking water sources also exceeded acceptable thresholds (10(-6)), indicating an increased risk of cancer for the population.
