AB  - A novel and simple air-assisted liquid-liquid microextraction (AALLME) is 
      introduced to analyze the organophosphorus pesticide (OPP) residues in fruit 
      juice samples, using the gas chromatography-flame photometric detection (GC-FPD). 
      In this method, fine extraction solvent drops are rapidly formed and dispersed 
      into the aqueous samples, by using a syringe to withdraw and push-out the mixture 
      of aqueous sample solution and extraction solvent several times. The parameters 
      affecting the extraction efficiency were investigated including the type and 
      volume of the extraction solvent, salt addition, extraction times, and pH. Under 
      optimized conditions, the method showed good linearities with the correlation 
      coefficients (gamma) higher than 0.9988, and the sensitivity with the limits of 
      detection (LODs) between 0.02mugL(-1) and 0.6mugL(-1). The method was applied to 
      determine the OPP residues in juice samples and the recoveries were ranged from 
      79% to 113% with relative standard deviations (RSDs) of 0.4-9.9%. The feasibility 
      of the method in real samples was proved.
