[Comparative evaluation of dust oncogenicity in asbestos-containing and non-asbestos details].

: Experiments proved higher carcinogenicity of chrisotyle-asbestos than of dust appearing in mechanical processing of asbestos-containing details and in wearing articulated shoe brakes. Substitution of asbestos for basalt fibers leaves oncologic risk intact among workers engaged into mechanical processing of asbestos-containing brakes. Avoiding asbestos in mixtures for brakes could lower risk. Results support conclusions obtained by cohort studies in Yaroslavl.
