摘要： Procymidone (PRM), a widely used amide-type fungicide in vegetables, poses potential health risks due to its high detection rate. This study introduces a pretreatment device and an intelligent quantification method for PRM in Chinese leek, cowpea, and celery using a lateral flow immunoassay (LFIA) integrated with a smartphone. The whole pretreatment and detection process can be achieved within 21 min. Recovery rates were 76.7%- 100.7% with an RSD of <12.6%, and the limit of quantification was 7.54-13.01 ng/g. Dietary risk assessment on 122 real samples from nine cities revealed that the chronic risk of PRM was all acceptable among different population group. However, the acute dietary in Chinese leek was unacceptable for children, with %ARfD of 125.20% at 97.5th percentiles. This work developed a convenient platform for on-site and rapid PRM detection, and provided scientific basis to protect human health from hazards of PRM.
