AB  - A reliable and simple analytical method was developed and validated to 
      simultaneously determine chlorantraniliprole and indoxacarb in tea using 
      ultrahigh-performance liquid chromatography-tandem mass spectrometry. The average 
      recoveries of chlorantraniliprole were in the range of 86-110%, with the 
      precision of intraday (n = 5) and interday (n = 15) ranging from 1.9 to 8.4% and 
      from 2.4 to 8.8%, respectively. The average recoveries of indoxacarb were in the 
      range 81-105%, with the precision of intraday (n = 5) and interday (n = 15) 
      ranging from 2.0 to 9.8% and from 2.7 to 9.1%, respectively. The limits of 
      quantification (LOQs) were all 0.01 mg/kg. The results based on the supervised 
      field trials showed that chlorantraniliprole and indoxacarb in two tea samples 
      followed first-order kinetics models with half-lives of 2.2-4.7 days and 
      2.5-3.5 days, which could be regarded as a moderately degrading pesticide. The 
      terminal residues of chlorantraniliprole and indoxacarb in made tea were below 
      6.7 and 4.5 mg/kg, respectively, lower than their corresponding maximum residue 
      limits (MRLs) established by several major countries and organizations (50 and 
      5 mg/kg). The leaching rates of chlorantraniliprole and indoxacarb during the tea 
      brewing ranged from 4.78 to 12.62% and 4.13 to 10.67%, respectively. The chronic 
      intake risk quotient (RQc) values for chlorantraniliprole and indoxacarb were 
      0.24% and 35.10%, while the acute dietary risk assessment (RQa) value of 
      indoxacarb was 5.8%, which were all much lower than 100%. The results in the 
      present study indicated that the health risk posed by the chlorantraniliprole and 
      indoxacarb mixture pesticides was negligible in tea for consumers at the 
      recommended dosages.
