摘  要：
研究了福建省12个县(市、区)郊区部分菜地土壤的汞污染状况,讨论了影响土壤汞累积及汞有效性的主要土壤学性质。结果表明:调查的菜地土壤全汞含量范围为0.038~1.81 mg·kg-1,其中有33.04%的土壤全汞含量超出国家土壤环境质量二级标准。土壤全汞含量与土壤粘粒、粉粒、有机质含量及CEC之间均呈极显著的正相关,说明这些土壤性质有利于汞在土壤中的累积。土壤有效汞含量范围为0.003~0.095 mg·kg-1,与土壤全汞含量之间呈极显著的线性正相关。土壤汞有效度随土壤有机质的增加而降低,表明有机质是影响土壤汞有效性的主要土壤学性质。

摘  要：
An investigation on mercury pollution of the soils was carried out over the vegetable fields at the suburbs of 12 countries of Fujian Province. The main soil properties which influenced the accumulation and the availability of soil mercury were discussed. Results showed that soil total mercury of the vegetable fields was 0.038~1.81 mg·kg-1, and 33.04% of the total soil mercury of the soil samples exceeded the National Secondary Standard for acidic agricultural soils. Total soil mercury had significant and positive correlations with the contents of clay,silt, organic matter, as well as CEC of the soils, indicating that these soil properties were in favour of the accumulation of mercury in the soils.The available soil mercury was between 0.003 mg·kg-1and 0.095 mg·kg-1, showing a significant and positive correlation with total soil mercury. The availability factions of soil mercury decreased with increasing soil organic matter, suggesting that organic matter was the major soil property which influenced the availability of mercury in the soils.
