Phthalic acid esters (PAEs) are one class of the most important plasticizers which are widely used in the production of plastic products. The accurate analysis of PAEs in seawater and sediment would be of great significance to study the transformation of PAEs and their ecological effects in marine environment. In this study, the method of gas chromatography with mass spectrum detector (GC-MSD) coupled with solid-phase microextraction had been established to analyze the concentration of PAEs in seawater and sediment, and various experimental conditions such as extraction time and extraction temperature were optimized. Under the optimum conditions, the precision was less than 10.0%, and the limits of detection were 0.04-0.32 μg/L and 0.12-1.60 μg/kg. Except dimethyl phthalate (DMP), the recovery of PAEs in seawater and sediment ranged from 68.0% to 114.0% and 76.4% to 105.0%, respectively. Moreover, the concentrations of PAEs measured with the method were 0.270-1.39 μg/L and 0.74-34.8 μg/kg in seawater and sediment samples of Changjiang River Estuary and its adjacent area, respectively. In conclusion, the analytical method is easy to operate and reduces the extraction volume of seawater water, thus it meets the requirements of the analysis of PAEs in coastal seawater and sediment.
