摘　　要：研究了北京市市售植物性油脂中全氟化合物的污染水平,测定了4个超市中大豆油、花生油、芝麻油等6类植物油中18种全氟化合物,结果表明:北京市售植物性油脂中均存在一定浓度的全氟化合物污染,其中品牌油脂中共检出8种全氟化合物,以全氟辛酸(PFOA)、全氟壬酸(PFNA)和全氟己酸(PFHxA)为主,其中调和油中的PFNA最高浓度达到4.64μg/kg,而在油作坊采集的压榨油脂中共检出15种全氟化合物,浓度均较品牌油脂高,其安全问题值得关注。对植物性油脂中全氟化合物的膳食风险评估结果显示,北京市售植物性油脂产品中PFOS和PFOA的污染水平和膳食暴露均在可接受的范围内。The pollution level of 18 PFCs in six kinds of vegetable oil such as soybean oil, peanut oil, sesame oil from four supermarkets in Beijing was studied. As a result, a certain level of PFCs were detected in the vegetable oil, such as 6 PFCs in a well-known brand oil, mainly PFOA , PFNA, PFHxA. And the highest concentration was PFNA with 4.64 μg/kg in blended oil. In crude oil, 15 PFCs were detected and the content was much higher than that in brand oil, more attention need to be paid on crude oil quality. Dietary risk assessment of PFCs in vegetable oil showed that the level PFOS and PFOA in vegetable oil in Beijing supermarket were all within acceptance range.
