摘要: 通过气相色谱-质谱联用结合NAGINATATM软件筛查了大豆油、葵花籽油、菜籽油和玉米油4 类34 种食用油样品中的有机污染物,并对污染物在食用油中的暴露水平进行了风险评估。结果表明,34 种食用油样品共筛查出有机污染物14~80 种,总含量在1.44~54.77 mg/kg之间,其中农药残留类含量在0.16~36.005 mg/kg之间,合成中间体类含量在0.095~9.78 mg/kg之间,其他类污染物(多环芳烃类和邻苯二甲酸酯类等)含量在0.045~19.725 mg/kg之间。对GB 2763—2014《食品中农药最大残留限量》和GB 2762—2012《食品中污染物限量》限定的有机污染物进行膳食暴露评估后发现,人群长期暴露在食用油中的部分有机污染物下的风险水平可以接受,其中高暴露水平的有机污染物为狄氏剂和灭除威,风险指数分别为3.35%~90%和4.50%~87.25%,需重点关注。

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.
