摘要: 通过野外取样调查和室内ICP-MS测定，研究了赣南典型稀土矿区周边土壤、动植物产品中稀土元素的组成特征，并评价了稀土元素对人体的健康风险.结果表明，赣南稀土矿区周边土壤稀土平均含量为402.74±200.03 mg·kg-1，分别是全国土壤稀土含量均值及世界土壤稀土中值的2.28倍和2.08倍；植物产品稀土平均含量为343.48 μg·kg-1；动物产品稀土平均含量为460.00 μg·kg-1；土壤、植物产品和动物产品中Ce含量最高，占总稀土比重分别为34.22%、35.31%和62.95%；其中轻稀土元素所占比重分别为75.29%、75.17%和75.82%.当地居民每日通过动植物产品摄入稀土元素日量为3.95-30.49 μg·kg-1·d-1，均值为10.36 μg·kg-1·d-1，均远低于稀土元素对人体亚临床损害剂量的临界值（110 μg·kg-1·d-1），表明赣南矿区周边动植物产品中稀土元素不会对消费者产生健康风险.Abstract: The composition characteristics and human health risks of rare earth elements (REEs) in soil, plant products and animal products from rare earth mining area in southern Jiangxi Province were examined by using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Results showed that the average concentration of REEs in soil around the rare earth mining area was 402.74±200.03 mg·kg-1, and 2.28 and 2.08 folds that of the average value of REEs in soil from China and the median value of REEs in soil all over the world, respectively. Average concentrations of REEs in plant and animal products were 343.48 μg·kg-1 and 460.00 μg·kg-1, respectively. The content of Ce in soil, plant and animal products the highest, accounting for 34.22%, 35.31% and 62.95% of the total REEs, respectively. The ratios of light REEs to total REEs in soil, plant and animal products around the rare earth mining area were 75.29%, 75.17% and 75.82%, respectively. The daily intake of REEs from agricultural products to local inhabitants varied between 3.95-30.49 μg·kg-1·d-1 with the average value of 10.36 μg·kg-1·d-1. These values were much lower than the critical value harmful to human health (110 μg·kg-1·d-1), suggesting no human health risk of REEs in plant and animal products around rare earth mining area in Southern Jiangxi Province.
