AB  - A sensitive method for simultaneous determination of pyridaben, dinotefuran, DN 
      and UF in eggplant ecosystem was established and validated through rapid 
      resolution liquid chromatography triples quadrupole tandem mass spectrometry 
      (RRLC-QqQ-MS/MS). Matrix-matched external calibrations were introduced to check 
      matrix effects. Limits of quantification (LOQs) of pyridaben, dinotefuran, DN and 
      UF in eggplant were 0.2, 0.2, 1.0 and 1.0 mug kg(-1), and 0.2, 0.2, 5.0 and 
      1.0 mug kg(-1) in soil, respectively. Limits of detection (LODs) of four 
      pesticides were below 0.41 mug L(-1). The mean recoveries (n = 5) of these 
      insecticides varied from 79.4% to 103%, and the relative standard deviations 
      (RSDs) ranged from 2.1% to 15.3% at three levels. This method was applied to 
      Chinese open-field samples from two representative locations, which were 
      previously treated with these insecticides at the doses of 210-315 g a.i. ha(-1) 
      twice or three times. The dissipations of pyridaben and dinotefuran in eggplant 
      and soil followed first-order kinetics with the half-lives of 3.65-11.4 d. The 
      residues of pyridaben and total dinotefuran (calculated as sum of dinotefuran 
      parent, DN and UF) in eggplant were below 0.0311 mg kg(-1) at the pre-harvest 
      interval (PHI, 7 d). Presently, no maximum residue limit (MRL) of pyridaben and 
      dinotefuran in eggplant was recommended by China, Codex Alimentarius Commission 
      (CAC) or European Union (EU). This study was important for evaluation of 
      environmental fate and food safety of pyridaben and dinotefuran in eggplant 
      ecosystems, and facilitated China to establish maximum residue limits (MRLs) of 
      pyridaben and dinotefuran in eggplant.
