摘要： Pesticides have represented a crucial tool to ensure the efficient production and development of modern agriculture; however, they inevitably polluted the environment and have posed threats to ecological security and human health. Although agricultural soil pesticide residues have long threatened the environment, a relatively complete system for evaluating their health and ecological risks has not yet been developed. To address this research gap, based on the health and ecological risk values calculated by a detailed detection of 50 pesticides on agricultural lands in Zhejiang Province, China, and supplemented by the analysis of soil microbial community composition, the present study proposed a comprehensive assessment system for pesticide residue risks. We found that 98.62 % of the soil samples contained more than ten pesticide types. Notably, while both carcinogenic and non-carcinogenic threat posed by pesticide residues to soil ecological security and human health was assessed as low, risk values varied significantly across different regions and agricultural practices. With an increase in the ecological risk of pesticide residues, the relative abundance of Firmicutes in the soil decreased significantly, indicating that Firmicutes may be used as an indicator of the ecological risk of pesticides. Taking advantage of differences in ecological risk, we also identified that some special microbial groups are substantially enriched in the face of pesticide pollution stress and can be used as candidate pesticide-degrading bacteria. This study investigated the correlation between pesticide residue risks and soil ecological security and human health, revealed the response characteristics of soil microbial communities under pesticide stress, and identified microbes strongly related to pesticide ecological risks. These findings can provide theoretical support for the future green management of pesticide residues in agricultural lands.
