Studies in the U.S.S.R. on the distribution, circulation, and fate of carcinogenic hydrocarbons in the human environment and the role of their deposition in tissues in carcinogenesis: a review.

The role of the retention of carcinogenic hydrocarbons in tis sues in earcinogenesis was demonstrated. Possible contamination of food with carcinogenic hydrocarbons is discussed and the measures for its prevention are planned. Much attention was given to the study of the exhaust gases of cars and to the preven tion of their carcinogenic action. The distribution of benz(a)pyrene in human environment and the fate of this substance were traced. Soil pollution with benz(a)pyrene is described; its destruction by some soil microorganisms is demonstrated.
