| Summary: | Elucidating the environmental fate and exposure risk of lufenuron is crucial to ensure food safety and protect human health. In this study, we developed a rapid and sensitive analytical method for tracing lufenuron in cabbages using ultra-high-performance liquid chromatography-tandem mass spectrometry. The occurrence, pharmacokinetic dissipation, and concentration variation of lufenuron were characterized by primary concentrations (0.009–0.420 mg/kg), half-lives (0.3 d–11.7 d), and final magnitude (<LOQ–0.320 mg/kg). A probabilistic model was introduced to assess dietary risks and presented a comprehensive picture of the risk at multi-probabilities. The chronic dietary risk (ADI%) of lufenuron were 1.074–5.609 % from the 50th to the 99.9th percentile. This was compared with deterministic models, which yielded ADI% values ranging from 0.177 % to 0.500 %, both of which were acceptable. The exposure risks of rural females aged 4–6 years were significantly higher than those of the other groups (P < 0.05), which should be taken seriously with the increasing requirement of lufenuron in actual agricultural production. |
