TI  - One-year routine application of a new and rapid method based on ultra performance 
      liquid chromatography-tandem mass spectrometry to the analysis of selected 
      pesticides in citrus fruits.
PG  - 535-40
AB  - A rapid method has been developed for monitoring five multiclass pesticides 
      commonly used in citrus fruits. The determination is performed by 
      ultra-performance liquid chromatography coupled to tandem mass spectrometry 
      (UPLC-MS/MS), after extraction with a mixture of ethyl acetate and sodium 
      sulfate. The method has been validated for orange matrix. Mean recoveries 
      obtained were between 74-110% with a repeatability precision of < 7%, 
      intermediate precision of < 10% and reproducibility precision of < 17%. Linearity 
      over the range 0.010-0.150 mg/kg was demonstrated (r(2) > or = 0.99) with limits 
      of quantification (LOQs) of < or = 0.01 mg/kg. Also, an analytical study focused 
      on the stability of pesticide residues in orange extracts under storage was 
      performed. The method has been applied to the analysis of 365 samples from the 
      agricultural area of the Valencian Community (Spain). Of 103 samples that 
      contained pesticide residues, only abamectin in 2 samples and carbendazim in 5 
      samples slightly exceeded the European maximum residue limits (MRLs).
