| 中文摘要: |
| 目前农田土壤重金属污染评价以重金属全量为依据，而评价农田土壤重金属污染影响时主要考虑农产品安全从而保障人体健康，农作物对重金属的吸收积累量则取决于土壤中有效态重金属含量。在阐述土壤重金属有效态定义的基础上，综合分析了土壤重金属有效态的影响因素及其与土壤中重金属全量和农作物中重金属含量的相关性，概括了土壤重金属有效态在土壤重金属污染评价中的应用，以期提出建立以土壤重金属有效态含量为基础、结合土壤重金属全量及作物中吸收的重金属含量的土壤重金属污染评价体系。 |
| 英文摘要: |
| At present, the evaluation of heavy metal pollution in farmland soil is based on the total amount of heavy metals. While the safety of agricultural products is mainly considered for ensuring human health. The absorption and accumulation of heavy metals in crops depend on the content of bioavailable form of heavy metals in soil. Based on the definition, bioavailable form of heavy metals influences and their correlation with the total amount of heavy metals in soil or in crops were summarized. In applying bioavailable form of heavy metal evaluation, a pollution assessment system was put forward based on the content of bioavailable form and the total amount of heavy metals in soil, and the absorption of heavy metals by the crops. |
