By using field survey, sampling, and indoor analysis, we analyzed the geochemical characteristics of heavy metals in the blueberries and soil of the core blueberry production area of Majiang in Guizhou, China. Analyses were based on national standards for soil pollution risk control on agricultural land (GB15618-2018) and pollution index limits in food (GB2762-2017/2012). The results demonstrated that heavy metal content in the soil profile of this area exceeds standards, but standards were exceeded mainly in the lower layer of the profile, and blueberry growth was not substantially affected. Except for in Lanmenggu, heavy metals in the cultivation soil layer of Majiang Blueberry Farms did not considerably exceed standards. The content of heavy metals in blueberry did not exceed the standard, so it was a safe fruit. These results can provide a reference for the safe cultivation of Majiang blueberries.

通过野外调查，抽样和室内分析，我们分析了贵州麻江核心蓝莓产区蓝莓和土壤中重金属的地球化学特征。分析基于农业土地上土壤污染风险控制的国家标准（GB15618-2018）和食品中的污染指数限制（GB2762-2017 / 2012）。结果表明，该地区土壤剖面中的重金属含量超过了标准，但主要在剖面较低层超过了标准，蓝莓的生长没有受到实质性影响。除蓝梦谷外，麻江蓝莓农场的耕作土壤层中的重金属含量均未超标。蓝莓中的重金属含量未超过标准，因此是安全的水果。
