Abstract: A gas chromatography-mass spectrometry method was developed for the determination of 18 PAEs in vegetables (Chinese cabbage, celery, tomato and cucumber), the residual monitor of PAEs of the vegetable in Anhui base was conducted in order to provide theoretical foundation for a safety diet to consumers and risk management suggestions to administrators. The results showed that the range of phthalate acid esters concentration of 0.05-5 mg/L had a good linear relationship with the correlation index of 0.9972-0.9998, the minimum detectable amount (S/N=3) was 0.05 ng; the average recovery range was 72.28%-112.57% under the level of 0.5-5.0 mg/kg, the relative standard deviation (n=5) was 0.94%-12.47%, this method could meet the demands of PAEs detection. The residual risk of 4 kinds of vegetables was monitored by this method, DIBP, DBEP, DEHP and DNP were found in the samples with the total contents of 0.20-0.72 mg/kg. DEHP was found in all of the 4 kinds of vegetables with the residual quantity of 0.02-0.22 mg/kg.
