WebbAlthough phenylalanine hydroxylase (PAH) is a liver enzyme, the clinical manifestations of classic PKU relate to the CNS. There are no abnormal metabolites formed in classic PKU but only excessive amounts of normal compounds. Therefore, it is logical to assume that elevated levels of blood phenylalanine are responsible for the toxicity. Webbtotal PAH fraction analysed was between 5 µg/day (low estimate) and 17 µg/day (high estimate). The intake of the carcinogenic PAH fraction was roughly half of these amounts. The largest contribution to the daily PAH intake came from sugar and sweets, cereals, oils, fats and nuts (11). Soil Carcinogenic PAHs are found in all surface soils.
