AB  - A new method was established to determine short-chain chloroparaffins (SCCPs) in 
      synthetic surfacing layers used in sports and diluents by solid-phase extraction 
      (SPE) coupled with gas chromatography-negative chemical ionization-mass 
      spectrometry (GC-NCI-MS). The analysis conditions for gas chromatography and mass 
      spectrometry were optimized. Then, the samples were extracted by ultrasonication, 
      purified on a Florisil SPE column, monitored in the selective ion monitoring 
      (SIM) scanning mode, and quantified by the external standard method. With this 
      method, a good linear relationship was found over a wide mass concentration range 
      from 0.0501 to 100.17 mg/L, with a linear correlation coefficient (R(2)) of 
      0.9995. The detection limit for SCCPs by this method was found to be as low as 
      0.50 mug/g (i. e. 0.000050%) and the average recoveries for SCCPs spiked in the 
      blank samples varied from 83.2% to 96.3% with relative standard deviations (RSDs) 
      of 1.56%-6.02%. Ten batches of samples were tested and the contents of SCCPs 
      detected in each batch were in the range from 0.016% to 0.55%, which agrees well 
      the European Union limitation requirement for SCCPs. Thus, this method is 
      suitable for qualitative and quantitative analyses of SCCPs in synthetic 
      surfacing layers used in sports and diluents.
