The Cd, Cu, Pb and Zn contents in home-grown crops in a former mining district were determined in order to evaluate the non-carcinogenic long-term potential health risk related to crop consumption. The potential health risk was investigated by estimating the daily intake and the hazard quotients. For all crop categories, the daily intake and the target hazard quotient were below the threshold values for Cd, Cu, and Zn. The daily intake of Pb exceeded the oral reference dose, while the target hazard quotient for vegetables was above 1, indicating a potential health risk. The total target hazard quotient for the individual metals decreased in the following order: Pb>Cd>Cu>Zn. This study confirmed that the daily consumption of crops grown in contaminated soils could pose health risks to humans.
为评估食用矿区本土种植作物带来的非致癌长期潜在健康风险，对这些作物中的镉、铜、铅和锌含量进行了测定。通过估算每日摄入量和危害商数来研究潜在健康风险。对于所有作物类别，镉、铜和锌的每日摄入量和目标危害商数均低于阈值。铅的每日摄入量超过了口服参考剂量，而蔬菜的目标危害商数高于1，表明存在潜在健康风险。各金属的总目标危害商数按以下顺序降低：铅>镉>铜>锌。本研究证实，食用受污染土壤中种植的作物可能对人类健康构成风险。
