Thirty-three soil samples were collected from the Luling, Liuer, and Zhangji coal mines in the Huaibei and Huainan areas of Anhui Province, China. The samples were analyzed for antimony (Sb) by inductively coupled plasma-optical emission spectrometry (ICP-OES) method. The average Sb content in the 33 samples was 4 mg kg(-1), which is lower than in coals from this region (6.2 mg kg(-1)). More than 75% of the soils sampled showed a significant degree of Sb pollution (enrichment factors [EFs] 5-20). The soils collected near the gob pile and coal preparation plant were higher in Sb content than those collected from residential areas near the mines. The gob pile and tailings from the preparation plant were high in mineral matter content and high in Sb. They are the sources of Sb pollution in surface soils in the vicinity of coal mines. The spatial dispersion of Sb in surface soil in the mine region shows that Sb pollution could reach out as far as 350 m into the local environment conditions. Crops in rice paddies may adsorb some Sb and reduce the Sb content in soils from paddyfields. Vertical distribution of Sb in two soil profiles indicates that Sb is normally relatively immobile in soils.
从中国安徽省淮北和淮南的芦岭、刘二和张集煤矿采集了 33 个土壤样本。采用电感耦合等离子体发射光谱法（ICP-OES）对样本中的锑（Sb）进行了分析。33 个样本的平均 Sb 含量为 4 毫克/千克，低于该地区煤炭中的含量（6.2 毫克/千克）。超过 75%的采样土壤表现出显著的 Sb 污染程度（富集因子[EF]在 5-20 之间）。在废弃矸石山和洗煤厂附近采集的土壤中 Sb 含量高于在矿区附近居民区采集的土壤。废弃矸石山和洗煤厂的尾矿中含有大量的矿物质和 Sb，它们是煤矿附近地表土壤 Sb 污染的来源。矿区表层土壤中 Sb 的空间分布表明，Sb 污染可能会扩散到 350 米以外的当地环境条件中。稻田中的作物可能会吸附一些 Sb，从而降低稻田土壤中的 Sb 含量。两个土壤剖面中 Sb 的垂直分布表明 Sb 在土壤中通常不易移动。
