Abstract 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 (GB27622017/2012). 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. Keywords  Majiang blueberry · Soil profile · Heavy metals · Exceed standard · Geochemical characteristics Blueberries are rich in nutrients, such as anthocyanins, organic acids, and phenolic acids, as well as flavonoids and polysaccharides. Soil is the basis of agricultural production, and the concentration of heavy metals in soil is a key indicator in environmental quality monitoring in areas where green products are produced (Zhang et al. 2004). Considering contemporary soil environmental problems, Zhang (2015) demonstrated that heavy metal pollution in soil and soil health problems in production areas seriously affect the ecology of agricultural production and the quality and safety of agricultural products. Therefore, to ensure healthy crop production, heavy metal concentrations in soil must be investigated to determine whether they exceed standard levels (GB156182018). Many scholars have researched heavy metal pollution in paddy soil (Rogan et al. 2010; Cui et al. 2018; Feng * Xuefeng Wen [email protected] Qihang Li [email protected] 1

These studies have provided suitable guidance for local agricultural production. Studies evaluating heavy metal concentrations in oranges, grapes (Alagić et al
