Zusammenfassung: | Background
Contamination of cow milk with uranium (U) is attracting global attention owing to U’s radio-toxicity and chemical toxicity in humans and animals. Concentrations of U in 223 cow milk samples from indigenous breeds reared in the proximity of a U mine in Zambia were measured using the inductively coupled mass spectrometry, and the human health risks from exposure to U through milk consumption were assessed.
Results
Milk from cattle reared in the U-mining area showed a significantly higher U-mean concentration (0.83 ± 0.64 µg/L;
t
= 9.95; tα = 0.05,
p
> 0.05) than milk from cattle reared in the non-mining area (0.08 µg/L ± 0.05). Among the residents of the U-mining area, the mean estimated daily intake (EDI), the target hazard quotients (THQs) and the target carcinogenic risks (TCRs) were all significantly (
