To analyze the content of dibutyl phthalate and bis(2-ethylhexyl)phthalate in main food, and assess the risk of dietary exposure of residents in Shibei District.Methods A total of 281 samples were collected from seven food categories and the identification and quantification were performed by GC-MS in selected ion monitoring(SIM) mode. The dibutyl phthalate and bis(2-ethylhexyl)phthalate exposure was estimated by the food consumption data.The health risk was assessed by comparing the dibutyl phthalate and bis(2-ethylhexyl)phthalate exposure with tolerable daily intake (TDI) and the margins of safety (MOS).Results In accordance with the mean value of food consumption estimates, the dibutyl phthalate and bis(2-ethylhexyl)phthalate exposure of Shibei District residents from 7 major food categories were 0.006 899 and 0.005 526 mg/kg BW, and didn't exceed the TDI. The MOS values were 7.2 and 1.8, both above 1.Conclusion In Shibei District, the phthalic acid esters in seven food categories were not intentionally adulterated. The contamination of phthalic acid ester had covered most of the food. The risk was low at present but further study about the long-term exposure was needed.
