中文摘要	利用电感耦合等离子体质谱仪(ICP-MS)对榆林市榆阳区砒砂岩与沙复配成土造田技术项目区砒砂岩、沙及砒砂岩与沙复配土的重金属(Cr、Ni、Cu、Zn、As、Cd、Hg和Pb)质量比进行测定,采用单因子污染指数法和内梅罗综合污染指数法对土壤污染程度进行评价。结果表明:除复配土和砒砂岩中Cd的平均质量比分别超出国家土壤环境质量自然背景值26.7%和102.8%外,复配土、砒砂岩及沙中其他重金属平均质量比均在国家土壤环境质量自然背景值以下;与砒砂岩相比,除Hg外复配土中Cr、Ni、Cu、Zn、As、Cd和Pb质量比分别下降了12.8%、40.7%、44.1%、49.3%、49.8%、37.6%和14.1%;砒砂岩与沙复配成土后,其Cr、Ni、Cu、Zn、As、Cd、Hg和Pb质量比均与沙中无显著性差异;复配土中Ni、Cu、Zn、As、Cd、Pb之间存在极显著的正相关关系,具有明显的同源性;复配土、砒砂岩及沙重金属单项污染指数均小于1,综合污染指数分别为0.314、0.503及0.200,污染级别为清洁。研究表明,砒砂岩与沙复配土的重金属质量比符合农田土壤环境质量标准,能够保证土壤环境质量安全和农产品品质安全。
英文摘要	The aim of the study is to provide an investigated data support for soil quality and crops safety of the compound soil consisting of arsenic rock and sand. For the said research goal, we have measured the contents of Cr, Ni, Cu, Zn, As, Cd, Hg and Pb by using the inductively coupled plasma mass spectrometry (ICP-MS) in the above said arsenic rock, sand and compound soil composed of arsenic rock and sand in a new farm land-making projectarea in Yuyang District of Yulin City. We have also assessed the pollution degree of the soil by means of the single factor pollution index and Nemerow comprehensive pollution index. The results of our investigation have shown that the ave rage content of heavy metals except for Cd still remain within the national soil environmental quality natural background value range, while the average Cd content of compound soil and arsenic rock turns out to be 26.7% and 102.8% higher than the national soil environmental quality natural background value, respectively. As compared with the arsenic rock, the contents of Cr, Ni, Cu, Zn, As, Cd and Pb in the mixed soil turn to decrease by 12.8%, 40.7%, 44.1%, 49.3%, 49.8%, 37.6% and 14.1% respectively, except for Hg. There seems no significant difference between the compound soil and sand in the contents of Cr, Ni, Cu, Zn, As, Cd, Hg and Pb. However, we have found that a very remarkable positive correlation among Ni, Cu, Zn, As, Cd and Pb contents in compound soil, which indicates that the heavy metals have obviously shared with the same source. In addition, the single-item pollution index of all kinds of heavy metals in the compound soil, arsenic rock and sand turns to be less than 1, the comprehensive pollution indexes are 0.314, 0.503 and 0.200 respectively, and the pollution degrees are clean. Therefore, it can be concluded that the contents of heavy metals in the compound soil, arsenic rock and sand are still coming to the farmland soil quality range, which is qualified to ensure the soil environment quality standard and the grain-production quality safety.
