| 摘 要： | 《土壤环境质量农用地土壤污染风险管控标准(试行)》(GB 15618-2018)给出了我国土壤环境质量的风险筛选值,但由于不同地区土壤组分及理化性质等方面的差异,使得该值对某些地区存在局限性.基于《食品安全国家标准食品中污染物限量》(GB 2762-2017)中给出的农作物中污染物的限值,以渝东南主要农耕区土壤中Cd为例、元素生物有效态的含量为基础划分建议筛选值.此方法可为重金属生物有效性较高、较低或Se元素含量丰富等典型地区完善土壤重金属及健康元素阈值提供借鉴和参考.

| Abstract: | The Soil Environmental Quality Risk Control Standard for Soil Contamination of Agricultural Land (GB 15618-2018) provides the risk screening value of soil environmental quality in China; however, because of differences in soil composition, and physical and chemical properties in different regions, this value has limitations for certain regions. Based on the limits of pollutants in crops given in the National Food Safety Standards Limits of Pollutants for Foods (GB 2762-2017), and using Cd in the soil of the main farming areas in southeastern Chongqing as an example, the content of the elemental biological effective state was determined for the suggested screening value. This method can provide a reference and method for improving the heavy metal and healthy element thresholds of soils with high or low bioavailability, and that are rich in Se content, among other factors. |
