Analysis of UK total-diet samples for polycyclic aromatic hydrocarbons was carried out using a simplified sample clean-up and a high-performance liquid chromatography dual fluorescence detector system. The results indicate that cereals and oils/fats contribute the major part (approximately one third each) of the polycyclic aromatic hydrocarbons in these total diets. Fruit, sugars and vegetables provide much of the remainder (approximately one quarter) while meat, fish, milk and beverages make relatively minor contributions. These results are compared with others in the current literature on polycyclic aromatic hydrocarbons in foods. The levels in the UK diet seem to be at least as low as those found elsewhere.
