[Setting normal levels of benz(a)pyrene in foods].

In the paper, methodological requirements are formulated for validation of permissible levels of benz(a)pyrene (B(a)P) in foodstuffs. A list is submitted of allowable levels of this carcinogen in food products for the population of Ukraine, their specific values being dependent on the accepted tolerance daily done intake and on the structure of the standard food ration. Prevention of B(a)P formation and its elimination from the human habitat together with the use of the modern environmentally appropriate technologies designed to prepare food products will form a basis for stabilization of the permissible dose of the carcinogen, finding its way to the human body as a food component through dietary intake.

[Methodological issues of standardization of environmental carcinogenic agents].

The paper considers the basic methodological principles for standardization of environmental carcinogenic agents. It shows it necessary to take into account carcinogenic hazards presented by environmental chemical pollutants. Emphasis is laid to the standardization of these substances in terms of the combined and complex action.

[Oncologic hygienic aspects of regulation of benz(a)pyrene in food products].

The paper presents a methodological scheme for regulating the acceptable levels of benz(a)pyrene in the foodstuffs is presented. It also gives a list of the acceptable levels of this carcinogen in the foodstuffs whose specific values depend on its daily dosage and the pattern of a standard diet for the Ukraine's population.

[Hygienic aspects of the study of the synthesis of nitrosamines from their precursors].

The paper presents data on the content of nitrosamines (NA), such an nitrosodimethylamine, nitrosodiethylamine, and their precursors (NO2 and amines) in the ambient air of different functional zones of a city. A high correlation between NA and NO2 in the air was established. NO2 was shown to have the leading role as a nitrosating agent in the model system and air during exogenous synthesis.
