AB  - The rapid screening of trace amounts of the nitrogenous disinfection by-products, 
      haloacetamides (HAcAms), in drinking and swimming pool water was performed by a 
      simple and reliable procedure based on salt-assisted liquid-liquid extraction 
      (SALLE) combined with injection-port silylation gas chromatography-mass 
      spectrometry (IPS-GC-MS) method. The optimal SALLE conditions involved the 
      injection of 4-mL of ethyl acetate into a 10-mL water sample (pH 7) containing 
      3-g of sodium sulfate. After vortex extraction for 1min and centrifugation, 10muL 
      of the extract (mixed with 1muL of MTBSTFA) was directly determined by IPS-GC-MS. 
      The limits of quantitation (LOQs) were determined to be 0.03-0.3mug/L. Precision, 
      as indicated by relative standard deviations (RSDs), was less than 10% for both 
      intra- and inter-day analysis. Accuracy, expressed as the mean extraction 
      recovery, was between 76% and 94%. The SALLE plus IPS-GC-MS was successfully 
      applied to quantitatively determine HAcAms from drinking and swimming pool water 
      samples, and the total concentrations of the compounds ranged from 0.43 to 
      4.03mug/L.
