摘要： The enrichment and health risk assessment of trace elements in crayfish on a national scale are significant for food safety due to the rapidly expanding crayfish consumption in China. In the present study, 4709 samples were extracted from databases to explore the spatiotemporal variation characteristics of trace elements in crayfish. Due to the variance in the background value of trace elements, the level of trace elements varies by region. Additionally, levels of As and Cr in crayfish increased with the promotion of intensive rice-crayfish coculture in China. Health risk assessment results revealed that trace elements may cause non-carcinogenic risk for crayfish consumption for adults and children from the mid-lower reaches of the Yangtze River, and the main risk was from As and Hg. The cancer risk values of As for children and adults in Zhejiang, Anhui, Heilongjiang, Hubei, Hunan, Jiangsu, Jiangxi and Shandong provinces were above the allowable value. There is concern about the non-carcinogenic and carcinogenic risk of consuming crayfish containing trace elements in some areas in China. Therefore, the results can serve as a critical reference for policy purposes in China. In addition, it is recommended that further research and assessment on crayfish consumption are required.
