由于食用菌对环境的污染，食用菌的安全性受到消费者的高度关注。本研究旨在提供和评价中国云南地区广泛采集的Wolfiporia extensaca菌核中As、Cd和Pb的含量数据。本研究以野生和栽培的野生稻为材料，对油菜菌核中As、Cd、Pb的含量进行了测定.通过电感耦合等离子体质谱法测定延伸率。结果表明，As、Cd和Pb含量均低于WHO规定的限量值，范围分别为5.27-161、1.51-42.1和< 1-634 ng g− 1干物质。计算的危害商数（HQ）和危害指数（HI）被用来评估非致癌性的健康风险，通过每日消费50克菌核的个别和组合的金属。通过食用菌核的HQ和HI均低于1，表明每周食用指定剂量的菌核对成年消费者不构成显著的健康风险。
Considering the environmental pollution, edible mushroom safety is of great concern to consumers. This study aimed at providing and evaluating data on As, Cd and Pb content of sclerotia ofWolfiporia extensacollected across Yunnan in China. For the presented survey As, Cd, and Pb concentration in sclerotia of wild and cultivatedW. extensawas determined by inductively coupled plasma mass spectrometry. The results showed that As, Cd, and Pb content were below the limit promulgated by WHO, with the ranges 5.27–161, 1.51–42.1 and < 1–634 ng g−1dry matter. Calculated hazard quotient (HQ) and hazard index (HI) were used to evaluate the non-carcinogenic health risk from individual and combined metals via daily consumption of 50 g sclerotia. Both HQ and HI through consumption of sclerotia were below 1, indicating that weekly consumption of sclerotia at the indicated doses poses no significant health risk to an adult consumer.
