An HPLC-fluorescence method was developed and used for the determination of 15 polycyclic aromatic hydrocarbons (PAH) in samples of milled wheat, finished cereals, milk powders, malt, spinach, and cooking oils. Results showed that the bran portion of milled wheat as well as finished bran ceral had a considerably high PAH content than other fractions or finished products. The use of direct heating or drying milk powders and malt was found in some cases to lead to elevated levels of PAH, and these were found to correlate with levels of nitrosamines present. Three samples of spinach had very low levels of PAH while two of three types of cooking oils had levels of carcinogenic PAH in the low micrograms per kilogram range. 18 references, 3 figures, 4 tables.
