产地土壤重金属对贺兰山东麓酿酒葡萄的影响及风险评估

Effects of heavy metals in soil on wine grape in the Helan Mountain’s Eastern Region and risk assessment

该实验以宁夏贺兰山东麓酿酒葡萄产区酿酒葡萄产区土壤为研究对象,探究产地土壤中重金属元素被葡萄吸收后对酿酒葡萄安全情况的影响及其相关关系。研究发现,贺兰山东麓酿酒葡萄产区土壤及酿酒葡萄中Cu、Cr、Pb、Cd、As、Hg、Fe、Mn、Zn元素平均含量分别为19.9 mg/kg、1.28 mg/kg,8.1 mg/kg、0.056 1 mg/kg,4.5 mg/kg、0.034 0 mg/kg,0.082 1 mg/kg、0.001 2 mg/kg,1.5 mg/kg、0.008 7 mg/kg,0.030 0 mg/kg、0.000 6 mg/kg,4.2 mg/kg、0.918 mg/kg,68 mg/kg、1.27 mg/kg,2.1 mg/kg、8.12 mg/kg。酿酒葡萄重金属含量与土壤中重金属含量均无显著正相关关系,土壤污染单因子指数表明酿酒葡萄产地土壤污染很低,每千克体质量每周可耐受摄入量(PTWI)和目标风险系数(THQ)表明,贺兰山东麓酿酒葡萄无重金属安全风险。

Using the soil of wine grape producing area at the eastern of Helan Mountain in Ningxia as the research object, the effect of heavy metals elements in the soil on the safety of wine grapes and the correlation between them were investigated. Results showed that the average content of Cu, Cr, Pb,Cd, As, Hg, Fe, Mn and Zn in the soil at the eastern of Helan Mountain was 19.9 mg/kg, 8.1 mg/kg, 4.5 mg/kg, 0.082 1 mg/kg, 1.5 mg/kg, 0.030 0 mg/kg,4.2 mg/kg, 68 mg/kg, and 2.1 mg/kg. The average content of heavy metals in wine grape was 1.28 mg/kg, 0.056 1 mg/kg, 0.034 0 mg/kg, 0.001 2 mg/kg,0.008 7 mg/kg, 0.000 6 mg/kg, 0.918 mg/kg, 1.27 mg/kg, and 8.12 mg/kg. The heavy metal contents between wine grapes and soil had no significant positive correlation, the single factor index of soil pollution indicated that the soil pollution in wine grape producing area was very low, provisionally tolerable weekly intake values(PTWI) and target hazard quotient(THQ) coefficient of per kilogram mass showed the wine grapes had no safety risks of heavy metals.
