An analytical method based on gas chromatography-mass spectrometry has been developed for the simultaneous determination of 4 flame retardants (tris (2-chloroethyl) phosphate, tri-o-cresyl phosphate, 2, 2', 4, 4', 5-pentabromodiphenyl ether and 2, 2', 3, 3', 4, 4', 6, 6'-octabromophenyl ether) in toys. Toy samples were extracted under ultrasonication for 30 min with n-hexane-dichloromethane (1∶1, V/V). The filtrate was injected into GC-MS and separated on a DB-5HT (15 m×0.25 mm×0.10 μm) chromatographic column. Qualitative and quantitative analysis was conducted under selected ion monitoring (SIM) mode. The limits of quantitation (LOQ) were 0.1 mg/kg for 4 flame retardants. The recoveries and relative standard deviations were 93.5%～97.3% and 2.4%～4.1%, respectively.
