摘要： In this study, a method for the determination of three medicinal and food homologous crops (fresh and dried Panax notoginseng, Lilium, and Lonicera japonica) was established, which had good linearity (R-2 > 0.9971), accuracy (77%-104%) and precision (intraday RSD of 0.4% to 8.9%, interday RSD of 1.7% to 7.8%). The limit of quantification (LOQ) was 0.01 mg/kg. Field results showed that there was a significant difference in the residue of lambda-cyhalothrin in the three crops. In Panax notoginseng, the residue level exhibited a trend of first increasing and then decreasing; in Lilium, the residue level was always lower than the LOQ; while the dissipation and metabolism of lambda-cyhalothrin in Lonicera japonica conformed to the first-order kinetic model, with an average half-life of 2.75 d. Chronic and acute dietary risk assessment the safety of lambda-cyhalothrin in the edible fraction of three crops was further evaluated with a risk quotient for chronic exposure (RQc) of 71.33% and a risk quotient for acute exposure (RQa) of 0.012%-0.345%, which indicates that it is unlikely to cause public safety problems.
