Abstract
The paper presents a study of natural chrysotile and 15 samples modifi ed using different temperature and pressure. The morphology, dimension s, chemical composition, crystalline structure, and technologic charac teristics of the samples studied were similar. The numbers of negative ly charged centers on the surface of fibers were about the same in all the samples. In two modified asbestos samples the number of positivel y charged centers was less than in the native one. In these samples th e energy of interaction of charged centers with macromolecules of roda min and eozin was also less than in the sample of natural chrysotile. It directly correlated with cytotoxicity and mutagenicity of them. The principal possibility to decrease the biological activity of asbestos lias been discussed.
