Phthalic acid esters(PAEs)are widely used as plasticizers in industrial production.At present,this type of pollut-ant has been widely detected in the global environment.The distribution characteristics and ecological risk pollution of phthal-ate organic pollutants in seawater and sediments near Xiamen were evaluated,and gas chromatography-mass spectrometry was used to determine the concentration of PAEs in the samples.The results showed that a total of 11 PAEs compounds were mainly detected in the aqueous and sedimentary environmental media,and the total PAEs mass concentration in water ranged from 45.9～251.1 ng/L,with an average concentration of 109.2 ng/L.The concentration in sediment ranges from 8.12～50.29 μg/kg,with an average concentration of 27.7 μg/kg.The risk entropy method was used to assess the risk of PAEs in the near sea area,and the results showed that DBP has a moderate ecological risk level.It is necessary to further trace the pollution emissions of PAEs in these areas.
