本研究的目的是调查世界上最大的和最长的运行在中国的钨矿区的土壤中的钨（W）污染和水稻富集。根区土壤和水稻植株取样在15个地点在农业领域毗邻W矿山和分析Al，Fe，Mn，Sc，W含量和W的化学形态在土壤样品和W含量在水稻根，茎，叶，和粮食样品。结果表明，土壤中W的含量范围为3.99至43.7 mg kg−1，90%以上的W在残留部分，显示其低流动性和生物有效性。水稻根、茎、叶和籽粒中的平均W含量分别为7.06、2.34、4.76和0.17 mg kg−1。此外，它们与土壤中的W含量和化学形态呈线性无关。根、茎、叶和籽粒的平均富集因子值分别为0.39、0.13、0.28和0.01。因此，大余县的钨开采活动污染了附近的农业土壤，导致了水稻对钨的生物富集。这可能会通过食物和土壤摄入对居民造成健康风险，这应该是审查的重点。
The objective of this study is to investigate tungsten (W) contamination in soil and its enrichment in rice in the area of the world's largest and longest-operating W mines in China. Root zone soil and rice plants were sampled at 15 sites in the agricultural field adjacent to W mines and analyzed for Al, Fe, Mn, Sc, and W contents and W chemical forms in the soil samples and W contents in the rice root, stem, leaf, and grain samples. Results showed that W content in the soil ranged from 3.99 to 43.7 mg kg−1, with more than 90% of W in the residual fraction, showing its low mobility and bioavailability. Average W contents in the rice root, stem, leaf, and grain were 7.06, 2.34, 4.76, 0.17 mg kg−1, respectively. In addition, they were linearly independent of W content and chemical forms in the soil. Average enrichment factor values were 0.39, 0.13, 0.28, and 0.01 for the root, stem, leaf, and grain, respectively. In can be concluded that W mining activity in the Dayu county contaminated the nearby agricultural soil and led to W bioaccumulation in the rice. This may pose a health risk to residents via food and soil ingestion, which should be a focus of scrutiny.
