| 摘 要： | 对长沙、株洲、湘潭6处脐橙园的土壤脐橙叶片、果实中镉含量进行了检测分析。结果表明,供测样品镉的检出率为83.33%,3处脐橙园土壤镉污染较重,3处脐橙园土壤镉未超标。果实中镉含量1处超标,5处低于安全标准。脐橙果实中镉的含量与土壤中镉含量成正相关。

Analysis of Cd Concentrations in Soil,Leaf and Fruit Samples of Navel Orange Orchards in Changsha-Zhuzhou-Xiangtang Region |

| Abstract: | The Cd concentration in soil leaves and fruits from 6 navel orange orchards in Changsha, Zhuzhou and Xiangtan was detected and analyzed. Cd was detected in 83.33% of the samples. Cd concentrations in soil samples of three orchards were high, while the concentrations in soil samples of other three orchards were within the allowed level. Cd concentrations in fruit samples of one orchard were above the safety standard level, while all the others were below the safety standard level. Cd concentrations in the fruit were positively correlated to the concentrations in the soil. |
