| 摘 要： | 对重庆市先锋街地区土壤中总铬含量进行测定、分析,并将其与对照土壤总铬含量进行比较,同时通过渗透实验,讨论了土壤对铬的吸附迁移规律。研究结果表明:该地区总铬含量虽基本符合土壤环境质量标准,但也有局部单元区土壤总铬含量超过环境质量标准的规定;土壤对铬的主要吸附深度为0~20cm。

| Abstract: | Based on the measurement of the content of total chromium in soil in Xianfengjie Area of Chongqing, comparison was made on this measured value with the content of the total chromium in the contrast soil. Absorption migration regularity of chromium in soil was discussed through osmotic experiment. The results showed (1) The content of total chromium in this area is approximately fitted for the environmental quality standard of soil, but the total chromium in some partial unit exceeds the standard value. In addition, the total chromium in this area is much greater than that in the contrast soil, with a large fluctuation. (2) The major absorption depth in this area is 0-20cm. if the soil depth is larger than 20cm, the level of total chromium in comparable to that in the contrast soil. |
