摘要：

In this study, in order to analyze the influence factors and sources of heavy metals in peanuts, the field experiment of geographical origin and variety was conducted. Peanut, soil, and precipitation samples were collected, and the concentrations of seven heavy metals were determined in all the samples. Combined with one-way analysis of variance (ANOVA), multi-way ANOVA, and Pearson correlation analysis, the influences of geographical origin, variety, and their interaction on the contents of heavy metals in peanut kernels were analyzed, and the relationships between the heavy metal contents in peanut and those in the provenance soil or precipitation were explored. The results indicated that the variations of Ni, Cd, and Tl contents in peanut were mainly affected by the region; the variation of As content was mainly affected by the interaction of origin and variety; while the variations of the contents of Cr, Sb, and Pb could be mainly affected by other factors. The contents of As, Sb, and Pb in peanut had no significant correlation with those in soil or precipitation; the contents of Cd and Ni in peanut had significant correlation with both soil and precipitation; and the contents of Cr and Tl in peanut were significantly related to those in soil. This study suggested that the contents of heavy metals in peanuts were affected by the origin and variety, and its sources include not only soil and precipitation, but also other sources such as pesticides and fertilizers. © 2022, Editorial Office of Journal of CIFST.
