The method previously described by Gertz [1] for the extraction of 3,4-benzopyrene in meat- and fishproducts has been adapted for butter, margarine, edible oils and fats and extended to other polycyclic aromatic hydrocarbons (PAH): 1,2-benzopyrene, 1,2,3,4-dibenzanthracene, 1,2,5,6-dibenzanthracene and 1,12-benzoperylene. The isolated PAH are determined by high-pressure liquid chromatography on reversed-phase columns with detection by fluorimetry. Recoveries range from 76 to 85%. The detection limit varies between 0.10 and 0.90 ppb. By application of optimized analysis conditions the sensitivity can be increased to 0.01 ppb for each compound.
格尔茨[1]先前描述的用于提取肉类和鱼类产品中3,4-苯并芘的方法已适用于黄油、人造黄油、食用油和脂肪，并扩展到其他多环芳烃（PAH）：1,2-苯并芘、1,2,3,4-二苯并蒽、1,2,5,6-二苯并蒽和1,12-苯并苝。分离出的多环芳烃通过反相柱高压液相色谱法测定，采用荧光检测。回收率在76%至85%之间。检测限在0.10至0.90 ppb之间变化。通过应用优化的分析条件，每种化合物的灵敏度可提高到0.01 ppb。
