A method was established for the determination of 8 UV absorbents in soils and sediments by dispersive solid phase extraction combined with gas chromatography-tandem mass spectrometry（GC-MS/MS).50 g sample was extracted by mechanical oscillation method for 30 min after addition of 20 mL hexane-acetone（4∶1

by volume)and purification with 1.0 g SCX sorbent.After concentration by rotary evaporator

the extract was determined by GC-MS/MS and quantified by external standard method.Parameters such as extraction solvents

extraction times and types of sorbent were optimized.Results showed that there existed good linear relationships for the target compounds in the range of 2-150 μg/L with their correlation coefficients（r2) not less than 0.994 7.The detection limits of the method were from 0.077 ng/g to 0.226 ng/g.The average recoveries at three spiked levels ranged from 95.7% to 126% with the relative standard deviations（RSD

n=8)not more than 12%.This method was successfully applied in the analysis of UV absorbents in real samples.The results showed that the detection rate for UV-328 was the highest.The method is simple

accurate and sensitive

and is applicable for the determination of UV absorbents in different types of soil and sediment samples.
