[Study of carcinogenic hazards of smoking kiln waste fumes].

The disperse phase of waste fumes forming during cold and hot fish smoking was studied by distributing the particles into 6 fractions and determining benz(a)pyrene (BP) in them. The level of BP in less than 2.5 mu was shown to be 85% whether smoking was hot or cold. The levels of 17 priority polycyclic aromatic hydrocarbons (PAH) were measured in three-dimensional fractions of fume particles. In all the fractions, phenanthrene and fluoranthene were of priority in weight. The proportion of BP in the total levels of PAH in waste fumes of cold and hot smokers was 0.69 and 0.74%, respectively and the carcinogenic activity was 46.42 and 49.0%. The investigations demonstrated that the waste fumes of smokers did not contain the particles that are PAH carriers.
