Objective The aim of this study was to evaluate the pollution status of phthalate esters（PAEs）in edible vegetable oils in Xi'an, in order to provide basic evidence for the government supervisory management. Methods PAEs were detected in vegetable oils samples collected from the market of Xi'an in 2015 using the method of GB/T 5009-2003. Results PAEs were found in 92.5% edible vegetable oils samples, which were DEHP, DNP, DIBP, DMP, DNOP and DBP. The detection rates were 92.5%, 17.5%, 5.0%, 2.5%, 2.5% and 1.25%, respectively.
