AB  - Sample pretreatment methods for the measurement of phthalate esters (PAEs) by gas 
      chromatography-mass spectrometry (GC-MS) in various complex matrices, including 
      sediment, soil, suspended particle matter, urban surface dust, Sinonovacula 
      Constricta, cosmet- ic, leather, plastic and coastal/estuarine seawater, were 
      proposed. The pretreatment which was appropriate for GC-MS detection was focused 
      on the investigation and optimization of oper- ating parameters for the 
      extraction and purification, such as the extraction solvent, the eluant and the 
      adsorbent of solid phase extraction. The results of the study of pretreatment for 
      various complex matrices showed that methylene chloride was the best solvent for 
      the ultrasonic extraction when solid-liquid extraction was used; silica gel was 
      the economical and practical adsorbent for solid-phase extraction for 
      purification; C18 was the most commonly adsorbent for preconcentration of PAE in 
      coastal/estuarine seawater sample; the mixed solution of n-hexane and ethyl 
      acetate with a certain proportion was the suitable SPE eluent. Under the 
      optimized conditions, the spiked recoveries were above 58% and the relative 
      standard deviations (RSDs) were less than 10.5% (n = 6). The detection limits 
      (DL, 3sigma) were in the range of 0.3 mug/kg (dibutyl phthalate)--5.2 mug/kg ( 
      diisononyl phthalate) for sediment, and 6 ng/L (dipropyl phthalate)--67 ng/L 
      (diisodecyl phthalate) for costal/estuarine seawater. The pretreatment meth- od 
      for various complex matrices is prominent for the measurement of the 16 PAEs with 
      GC-MS.
