AB  - A recently reported microextraction technique namely air-assisted liquid-liquid 
      microextraction (AALLME) has been described for the extraction/preconcentration 
      of some triazole pesticides from different samples prior to gas 
      chromatography-flame ionisation detection (GC-FID). This technique is similar to 
      dispersive liquid-liquid microextraction (DLLME) but in this method there is no 
      need to use a disperser solvent and also volume of the used extraction solvent is 
      less than DLLME. In this study, toluene with a density lower than that of water 
      was used as an extraction solvent. Under the optimum extraction conditions, the 
      method showed wide linear ranges with R(2)>0.996 and low limits of detection and 
      quantification between 0.53-1.13 and 1.76-3.77 ng mL(-1), respectively. 
      Enrichment factors (EFs) and extraction recoveries (ERs) were in the ranges of 
      713-808 and 100-113%, respectively. Relative standard deviations (RSDs) for the 
      extraction of 25 and 250 ng mL(-1) of each selected triazole pesticide were less 
      than 7% for intra-day (n=6) and inter-days (n=5) precision. The method was 
      successfully used for analytes determination in different surface water, grape 
      juice, cucumber, and tomato samples.
