摘　　要：利用气相色谱质谱仪（GC-MSD）对北京市4家超市销售的大豆油、花生油、芝麻油等7类植物油中16种优控多环芳烃进行检测,结果显示7类食用植物油样品多环芳烃（PAHs）污染较为普遍,∑16PAHs中芴、菲和艹屈检出率最高。∑16PAHs在不同种类食用植物油中平均浓度为：芝麻油〉花生油〉葵花籽油〉调和油〉橄榄油〉大豆油〉玉米油。∑8PAHs/∑16PAHs的比值为0.08-0.32。7类食用植物油中PAHs的潜在致癌风险为：花生油〉葵花籽油〉调和油〉芝麻油〉玉米油〉大豆油〉橄榄油。通过PAHs的健康风险评估可知,北京成年居民通过食用植物油摄取PAHs的健康风险在可接受的范围内。Sixteen polycyclic aromatic hydrocarbons （∑16PAHs） were determined by gas chromatography mass spectrometry （GC-MSD） in 7 kinds edible vegetable oil samples from Beijing supermarkets. The results showed that PAHs pollution was more common in 7 kinds of edible vegetable oil samples. The detection rate of fluorene, phenanthrene and chrysene was the highest in ∑16PAHs. According to the average content of ∑16PAHs the descending order of different kinds of edible vegetable was： sesame oil 〉 peanut oil 〉 sunflower oil〉 blend oil 〉 olive oil〉 soybean oil 〉 corn oil. The ratio of the ∑8PAHs/∑16PAHs was 0.08–0.32. PAHs potential cancer risk in 7 kinds edible vegetable order was： peanut oil〉 sunflower oil〉 blend oil 〉 sesame oil 〉 corn oil〉 soybean oil〉 olive oil. The health risk assessment of PAHs showed that the edible vegetable oil intake risk of PAHs by adult in Beijing was within the acceptable range.
