摘要：

Heavy metal pollution and dietary risk assessment of Boletaceae from different parts of Yunnan Province were conducted in this paper. The contents of Cd, As and Pb in 9 species of Boletaceae in Yunnan Province were determined by ICP-MS, and the content characteristics of different parts were analyzed. The single factor pollution index and Nemerow comprehensive pollution index were used to evaluate the heavy metal pollution of Boletaceae. Objective hazards quotient method was used to evaluate the health risk of Boletaceae. It was found that the contents of Cd, Pb and As in Boletaceae exceeded the standard in varying degrees. The enrichment of heavy metals may be related to the location, species and origin. The highest content of Cd was 20.89 mg/kg. Cd was the main heavy metal pollution source of Boletaceae, and it played a leading role in the comprehensive health risk. The difference analysis showed that there were significant differences in heavy metal contents in most of the same species, same parts and different habitats. There was no significant difference in heavy metal content of the same species of Boletaceae from the same urban area. The pollution degree of different types and parts was different. Most of the three heavy metals in Boletaceae were Pi>1. The comprehensive pollution index showed that there were more samples of mild and severe pollution. The purpose of this study is to provide reference to the development and utilization of resources and reasonable diet for consumers. © Chelyabinsk Physical and Mathematical Journal.
