TI  - Multi-residue analysis of pesticide residues in mangoes using solid-phase 
      microextraction coupled to liquid chromatography and UV-Vis detection.

AB  - A sensitive and efficient solid-phase microextraction method, based on liquid 
      chromatography and UV-Vis detection, was developed and validated as an 
      alternative method for sample screening prior to LC-MS analysis. It enables the 
      simultaneous determination of ten pesticides in mango fruits. The fiber used was 
      polydimethylsiloxane while optimum SPME conditions employed have been developed 
      and optimized in a previous work. The desorption process was performed in static 
      mode, using acetonitrile as a solvent. The results indicate that the 
      DI-SPME/HPLC/UV-Vis procedure resulted in good linear range, accuracy, precision 
      and sensibility and is adequate for analyzing pesticide residues in mango fruits. 
      The limits of detection (0.6-3.3 mug/kg) and quantification (2.0-10.0 mug/kg) were 
      achieved with values lower than the maximum residue levels (MRLs) established by 
      Brazilian legislation for all pesticides in this study. The average recovery 
      rates obtained for each pesticide ranged from 71.6 to 104.3% at three 
      fortification levels, with the relative standard deviation ranging from 4.3 to 
      18.6%. The proposed method was applied for the determination of the 
      aforementioned compounds in commercial mango samples and residues of 
      azoxystrobin, fenthion, permethrin, abamectin and bifenthrin were detected in the 
      mango samples, although below the MRLs established by Brazilian legislation.
