锑是近年来受到普遍关注的有害微量元素,广泛的存在于环境中。煤炭的开采利用向环境中释放的锑成为煤矿区环境中锑的重要污染源。矿区承载了煤的开采堆放加工等诸多活动.然而锑在煤矿区的分布及其相关的环境效应至今报道较少。本文以安徽淮北芦岭矿区为研究对象.共收集38个表层土壤样和塌陷湖及周边水体水样。通过分析得出:锑在土样中的平均浓度为4.5×10^-6,矸石堆放和煤的洗选是矿区土壤中锑的重要来源,已形成轻度污染。锑主要与土壤中固定相结合,但矿区的强氧化环境和酸性废水会加速矿物中锑的释放;三个塌陷湖和背景水体中锑的平均浓度分别为1.3×10^-9和0.7×10^-9,主要来源于矿区的人为活动.但尚未在水深40~60cm处形成富集,基于多个饮用水标准.评价其仍可作为矿区的生活和饮用水源。
Antimony(Sb) has been paid more and more attention recently because of its potential toxicity in environment. Usage of coal plays an important role in release of Sb. During mining, combustion and other utilization processing of coal, Sb is prone to volatilize into atmosphere and enrich in different residue, especially in coal mine field while the investigation on which is scarce. In this paper, we look into Luling coal mine in Huaibei of Anhui and collect 38 samples of surface soil and water. The surface soil is polluted with the average content of Sb is 4.5 ×10^-6 which is mainly caused by the deposition of coal parting and coal cleaning process. But the release maybe accelerated due to the increased oxidation rates and acid mine drainage; mean content of Sb in slumping water is 1.3×10^-9 which show slight pollution comparing with 0.7 ×10^-9 of Sb in flowing creek water. It's concluded that slumping water in Luling mine is secure for everyday living and drinking purpose.
