人可通过烟灰、煤焦油、沥青、煤油及烟草、熏制食品和烘烤食品等接触到早已证明为致癌剂的多环芳烃类,但因苯并芘[B(a)P]发现最早及广泛存在,故受到普遍重视。本文报道了用质谱-气相色谱(GC-MS)对意大利市售的熏制、烘烤食品及油脂和经烹调加工后的食品中的B(a)P进行测定。调查中用质谱碎片图谱的方法进行样品萃取液B(a)P的定量测定,以B(a)P作外标,加入B(a)P的回收率为93～95%。质谱-气相色谱仪的操作条件为烘箱温度(恒温)是250℃; People can get access to PAHs that have long been proved to be carcinogenic by using soot, coal tar, asphalt, kerosene and tobacco, smoked foods and bakery products, but the earliest and widespread discovery of benzopyrene [B (a) P] Exist, it is generally valued. This paper reports the determination of B (a) P in smoked, baked and fat products and processed foods processed in Italy using mass spectrometry-gas chromatography (GC-MS). In the investigation, the quantitative determination of B (a) P in sample extract was carried out by mass spectrum fragment spectrum. The recovery of B (a) P was 93-95% with B (a) P as external standard. Mass spectrometry - gas chromatograph operating conditions for the oven temperature (constant temperature) is 250 ℃;
