[Investigation of the content of carcinogenic compounds in commercial smoked fish].

The authors performed investigations of the content of polycyclic aromatic hydrocarbons (PAH) (n = 17) and their nitro derivatives (n = 5) in commercial cold and hot smoked herrings and greenlings. The level of benz(a)pyrene in all fish samples was found to be well below the current sanitary and hygienic limits. The concentration of N-nitrosoamines in cold smoked fish was slightly below that in hot smoked one. The content of nitro derivatives of PAH in fish is indicative of the low significance of these compounds in the total negative potential of smoked fish.
