| 摘 要： | 为探讨土壤环境中As、Hg元素对土壤环境质量和农产品质量安全的影响,选取贵州具有代表性的几个农业种植区,对不同地质背景和不同农产品中As、Hg元素在母岩一深层土-浅层土-农产品中的含量变化进行了对比分析.结果表明:农产品中As、Hg元素含量与其土壤元素背景含量虽然存在一定的关系,但其受土壤理化性质及农作物自身种属的影响更大.此外,作为As、Hg元素高背景含量的碳酸盐岩区,在其特殊的地质环境特征下,其农作物中并没有富集过量的As、Hg元素.As、Hg元素的高背景含量反映在农作物上仍然是安全的.

| Abstract: | Several crop production areas in Guizhou province were selected to study the effects of arsenic and mercury on soil environmental quality and quality security of agricultural products. A comparative analysis was conducted on mercury and arsenic content changes in parent rock, deep soil, shallow soil and agricultural products under different geological background (carbonate area and non-carbonate area) and in different agricultural products. The results showed that the content of arsenic and mercury in agric... |
