Soils and vegetables were sampled and analyzed from nine vegetable fields in Guilin area, China. The average mercury (Hg) concentrations varied from 0.099 to 0.546 mg/kg in soils and from 0.046 to 0.132 mg/kg in plants. The distribution of Hg pollution in plants was correlated with that in soils. Generally, the Hg concentration in the plants decreased with the increasing distance between sampling sites and the city center. The Hg existed mostly in leaves of the plants, and then in their roots and stems, which suggested that the Hg in the atmosphere might be an important source of Hg in plants.
在中国桂林地区的九个蔬菜田中采集和分析了土壤和蔬菜样本。土壤中汞（Hg）的平均浓度从 0.099 到 0.546mg/kg 不等，而植物中的汞浓度从 0.046 到 0.132mg/kg 不等。Hg 污染在植物中的分布与在土壤中的分布相关。一般来说，Hg 浓度在植物中的含量随采样点与市中心的距离增加而降低。Hg 主要存在于植物的叶子中，其次是根和茎，这表明大气中的 Hg 可能是植物中 Hg 的一个重要来源。
