| 摘 要： | 本文研究了浙江富阳金属冶炼厂周围水田土壤-水稻系统中As、Se含量特征。所采土壤样品中,As含量高于土壤环境质量一、二和三级标准的分别占总数的21.15%、9.62%和7.69%。该金属冶炼厂周围88.46%的土壤属于富Se土壤。足Se土壤占总样的5.77%,过量Se土壤占3.85%,高Se土壤占5.77%。水田土壤可能受与金属冶炼有关的点源污染影响。糙米的As、Se含量高于全国糙米As、Se背景值,可食部分As、Se浓度均未超过我国规定的水稻卫生标准。

| Abstract: | In this study, the characteristic of As and Se contents in paddy soil-rice system in the vicinity of a nonferrous metal smelter was investigated. The total As content in 21.2% of soil samples exceeded the first class of Chinese Soil Environmental Quality Standard, 9.62% above the second class and 7.69% above the third class. Most of soils contained enough Se content or abundant Se. The percentage of soil with rich Se content from 0.45 to 2.00 mg/kg was 88.46%. As and Se contents in crude rice was far higher than national background values, although As and Se contents in edible parts did not exceed the Chinese quality standard for rice grains. The metal smelters had led As and Se pollution in soil- rice system. |
