In order to explore the heavy metal pollution in the soil-kiwifruit system and the health risk of heavy metals ingestion by eating kiwifruit,this study used the single factor pollution index and Nemerow comprehensive pollution index to evaluate the degree of soil heavy metals pollution,and analyzed the excessive heavy metals in kiwifruit according to the relevant standards of the heavy metal limit value.The health risk of consumption of kiwifruit was assessed by the non-carcinogenic risk index and carcinogenic risk index,and the enrichment of heavy metals in soil-kiwifruit system was discussed based on correlation analysis and element bioconcentration factor.The results showed that there was only slight Cd pollution in the soil of kiwifruit orchard in the study area,and the overall pollution was light.Meanwhile,only 4％of the samples of kiwifruit had Pb exceeding the standard,and the Cd did not exceed the standard in kiwifruit.The As,Cd,Cr,Hg and Pb ingestion of kiwifruit had a low probability of causing human health risks in the study area.Among them,As,Cd,Cr and Pb were the main contributing factors of non-carcinogenic risk,while Cd was the main contributing factor of carcinogenic risk.The absorption of heavy metals by kiwifruit had nothing to do with the content of heavy metals in soil,and the ability of heavy metals to migrate,transform and accumulate in soil-kiwifruit system was low.
