Concentrations of heavy metals (As, Cd, Co, Cr, Cu, Hg, Pb and Sb) in vegetables, meat and fish purchased from traditional agri-product markets in Huainan, China, were measured. Concentrations of the eight metals in most of the measured samples were lower than their respective maximum allowable concentrations (MACs), except for Pb, Cd, Cr and Cu in some of the samples exceeded safe limits. Based on local food consumption, the intake of individual metals was estimated to be less than their respective recommended limits. However, the overall target hazard quotient (THQ) for the eight metals was 1.07 based on the digestion of leafy vegetables and 2.12 based on the consumption of all of the investigated foods. The results of this study suggest that the overall risk from exposure to multiple metals in foods should be of concern, even though low-to-moderate heavy metal pollution is present in foods from Huainan markets.
对从中国淮南传统农产品市场购买的蔬菜、肉类和鱼类中的重金属（砷、镉、钴、铬、铜、汞、铅和锑）浓度进行了测量。在大多数被测样品中，这八种金属的浓度低于各自的最大允许浓度（MAC），但部分样品中的铅、镉、铬和铜超过了安全限值。根据当地的食物消费量，估计个体金属摄入量低于各自的推荐限值。然而，基于叶菜类蔬菜的消化情况，这八种金属的总体目标危害商（THQ）为1.07，基于所有被调查食物的消费情况则为2.12。本研究结果表明，即使淮南市场的食品中存在低至中度的重金属污染，食物中多种金属暴露带来的总体风险仍应受到关注。
