Abstract: The organic pollutants were investigated by gas chromatography-mass spectrometry (GC-MS) using NAGINATATM software and the health risks associated with dietary exposure to them were assessed in 34 samples of 4 kinds of edible oils, soybean oil, sunflower oil, rapeseed oil and corn oil. The results showed that 14 to 80 organic pollutants were found in the investigated oils with their total concentrations varying from 1.44 to 54.77 mg/kg. Moreover, among these pollutants, the total amounts of pesticide residues, synthetic intermediates and others (polycyclic aromatic hydrocarbons, phthalic acid esters, etc) were in the range of 0.16–36.005, 0.095–9.78 and 0.045–19.725 mg/kg, respectively. According to the Chinese national standards GB 2763—2014 and GB 2762—2012, dietary exposure assessments for some organic pollutants were carried out. It was found that the risk level at which people were exposed to the organic pollutants in edible oils chronically could be accepted. Moreover, much attention should be given to dieldrin and 3,5-dimethylphenomethylcarbamate (XMC) due to their high exposure level at 3.35%–90% and 4.50%–87.25%, respectively.
