Fritillaria thunbergii Miq. (Zhe Beimu, F. thunbergii) is widely cultivated in China's Zhejiang province, and pesticides and heavy metals are two major factors affecting its quality and safety. A total of 106 F. thunbergii samples from six main production areas were analyzed for 76 pesticides and four heavy metal content (As, Cd, Hg, and Pb). The pesticide detection rate of the samples was 66.98%; overall, the pesticide residues were very low, and residue levels ranged from 0.010 to 0.231 mg kg. The detection rates of As, Cd, Hg, and Pb were 95.3%, 100%, 76.4%, and 100%, respectively. A risk assessment of human exposure to pesticides and heavy metals via intake of F. thunbergii was performed, and the results revealed that the pesticide residues and heavy metal content detected in F. thunbergii does not pose a potential risk to human health, either in the long or short term. The exposure assessment showed that the levels of pesticides and heavy metals in F. thunbergii were safe for human consumption. These results provide useful information on F. thunbergii consumption.
浙贝母（Fritillaria thunbergii Miq.，浙贝）在中国浙江省广泛种植，农药和重金属是影响其质量和安全的两个主要因素。本研究对来自 6 个主产区的 106 个浙贝母样本进行了 76 种农药和 4 种重金属（As、Cd、Hg 和 Pb）含量的分析。样本的农药检出率为 66.98%；总体上，农药残留水平非常低，残留水平范围为 0.010 至 0.231 mg kg。As、Cd、Hg 和 Pb 的检出率分别为 95.3%、100%、76.4%和 100%。通过摄入浙贝母对人体暴露于农药和重金属的风险进行了评估，结果表明，浙贝母中检测到的农药残留和重金属含量无论是长期还是短期，都不会对人体健康构成潜在风险。暴露评估表明，浙贝母中的农药和重金属含量对人体食用是安全的。这些结果为浙贝母的食用提供了有用的信息。
