OBJECTIVE: To investigate the contamination of 2-chloropropanol esters and 3-chloropropanol esters in commercial edible vegetable oils in Shandong Province, and to assess the dietary 3-chloropropanol esters exposure and the health risk of intaking 3-chloropropanol esters. METHODS: From 2016 to 2020, 406 individually packaged edible vegetable oils were collected from stores and farmers' markets in 16 prefecture-level cities in Shandong Province. According to the 2016 National Food Contamination and Harmful Factors Risk Monitoring Manual, using gas chromatography-triple quadrupole tandem mass spectrometry detection, isotope internal standard method for quantification, laboratory determination of 2-chloropropanol ester and 3-chloropropanol in vegetable oil ester content. Combined with population weight, oil consumption and monitoring data, the point assessment method was used to evaluate the exposure of residents in Shandong Province to 3-chloropropanol esters. RESULTS: The detection rate of 3-chloropropanol ester was 92.4%(375/406), the concentration range was
