AB  - OBJECTIVE: To develop a method for detecting 11 organophosphate pesticides and 
      atrazine in water samples by dispersive liquidliquid microextraction combined 
      with gas chromatographymass spectrometry (DLLMEGC/MS) . METHODS: DLLME and GCMS 
      parameters were optimized for efficient extraction of chemicals. The proposed 
      method was used for detecting organophosphate pesticides in tap water and river 
      water samples,with 200 muL of dimethylbenzene as extractant and 800 muL of methanol 
      as dispersant. They were mixed,emulsified and dispersed into 10 mL of water 
      samples. The extractant (1 muL) from centrifugation was injected into the GC/MS 
      system for analyses. GC separation was performed on HP5 column (30 mx0.25 mm,0.25 
      mum) by temperature programming. Mass spectrometric analysis was done with EI and 
      selected ion monitoring (SIM) mode was used for quantitative analysis. RESULTS: 
      Good linear ranges for detecting the 11 pesticides and atrazine appeared from 2.0 
      ng/mL to 50 ng/mL,with a limit of 0.121.38 ng/mL. The relative standard 
      derivations (RSDs) ranged from 5.57% to 9.85%. The average recoveries ranged from 
      75.5% to 107%. CONCLUSION: The method is sensitive and rapid,with simultaneous 
      extraction and concentration procedures. The lowdensity organic solvent after 
      extraction is easy to isolate. The method fits for analyses of organophosphate 
      pesticides and atrazine in water samples.
