| Abstract: | Cd, Pb, Cu and Zn were measured in vegetables in Xiguadi village around Lechang Pb/Zn mine in Guangdong province, South China.
The daily intake (DI) of these metals from vegetables by local people was also determined. The respective Cd, Pb, Cu and Zn
concentration was 0.05–0.90 (mean 0.25), 1.04–5.82 (2.64), 0.53–7.07 (2.00) and 3.87–25.20 (11.68) mg kg−1, of which Cd concentration in all vegetables exceeded the safe limit given by FAO/WHO. The DI was found to be 49.76, 475.56,
360.36 and 2,102.63 μg, respectively. The present results indicated local mining activity caused vegetable heavy metal contamination
and Cd concentration exceeding the stipulated standards for all vegetables indicating potentially serious dietary risks for
local people. |
