| 摘 要： | 研究在江汉平原中部的仙桃市沙湖镇沙湖农场南洪村、洪湖市黄家口镇姚河村钻凿3个深度约为30 m的钻孔,采集不同深度代表性岩土样(单孔内取样间距为2 m),采用用银盐法测定沉积物样品中砷含量。研究结果表明,该研究区域沉积物中砷含量范围为1.500～17.289mg/kg,与典型的现代松散型沉积物中砷含量相当(510 mg/kg);砷含量最大值均出现在泥土层,最小值均出现在沙层,表明沉积物样品中砷含量与岩性有密切关系。

| Abstract: | Three boreholes with the depth of 30 m were drilled and collected representative geotechnical samples at different depths(sample spacing within the single-hole 2 m) for laboratory analysis.Arsenic content in the sediment core samples was investigated with DDC-Ag method.Results show that the content of arsenic in the study area is ranged from 1.500 mg/kg to 17.289 mg/kg,which is fairly similar to modern loose sediment arsenic concentration of 5~10 mg/kg.The maximum arsenic content exists in the soil layer,while the minimum arsenic content exists in the sand layer,which indicates that the arsenic content in the sediment samples is closely associated with the lithologic structure. |
