摘要：Heavy metal contamination in orchards has received increasing attention as people pay more attention to food safety issues. In this study, the levels of six heavy metals (Cu, Ni, Pb, Zn, Cd and Cr) in soil and fruit (peel and pulp) of 70 kiwifruit orchards in Xiuwen County, Guizhou Province, China, were investigated by inductively coupled plasma mass spectrometry (ICP-MS), and correlation analyses as well as dietary risk assessment. The results showed that the mean concentrations of the six heavy metals (Cu, Ni, Pb, Zn, Cd and Cr) ranged from 0.41-104.02 mg kg(-1) in soil, <0.01-2.15 mg kg(-1) in peel and <0.01-0.23 mg kg(-1) in flesh, with the heavy metal content in flesh being significantly lower than that in peel. Among the 70 soil samples in this study, some samples of Cd, Ni, Cu and Zn exceeded the secondary standard for soil environmental quality in China, and the proportions of Cu, Ni, Pb, Zn, Cd and Cr exceeding the geochemical soil background values in Guizhou were 72.86%, 72.86%, 64.29%, 52.86%, 48.57% and 37.14%, respectively. The results of the correlation analysis indicated that the higher the Cu content in the soil, the more favorable the transfer and enrichment of Cr, Cd, Cu, Zn and Ni to kiwifruit fruit, and the less favorable the enrichment of Pb. The results of the food safety risk assessment indicated that none of the six heavy metals in kiwifruit posed a significant risk to human health. This study can provide a reference for the regular investigation of heavy metal pollution in kiwi orchards and the long-term safety of kiwifruit.
