Abstract: A study on short chain-chlorinated paraffins (SCCPs) in plastic toys was conducted by means of a GC-MS detection technique, and the extraction temperature, procedure and solvent were optimized. The total ion current confirmation, qualitative and quantitative ion analyses and GC-MS detection for the content of SCCPs in plastic toys were also carried out. The results indicated that there was a good linear relationship for SCCPs, and its linear correlation coefficient for the calibration curves reached 0.999 9. The detection limit was in the range of 0.052 4~0.197 mg/L, and the recover rate reached 85.4 %~90.9 %. The chromatographic analysis for the SCCPs with three different chlorine contents could be used for the confirmation of chlorine species in SCCPs. This method is simple, rapid, highly sensitive and quantitatively accurate. The results indicated that this method could be used for the measurement of plastic toys contained 24.42~52.46 mg/kg of SCCPs.
