An analytical method was developed for determining benzo(a)pyrene in foods. The method consists of four cleanup steps: alkali cleavage of sample; preliminary silica gel column chromatography; selective extraction with concentrated sulfuric acid; and further silica gel column chromatography. Apparatus, reagents, and procedure used are described. Recoveries of benzo(a)pyrene added to 50 g food at levels of 0.4 ppb ranged from extraction step affords a simple method for isolating benzo(a)pyrene from various kinds of interfering substances that could not be separated by existing methods. 11 graphs, 12 references, 3 tables.
