[Harmonization of national and foreign sanitary laws on industrial aerosols].

According to existing hygienic norms in Russian Federation, dust control covers a whole mass of particles contained in air of workplace--that is based on biologic value of all mass of dust affecting human, rather than of separate dust fractions, as is accepted abroad. State Standard specification R 54578-2011 establishes general principles of hygienic regulation, control and evaluation of occupational diseases risk due to aerosols with predominantly fibrogenous effects through measuring mass concentration of all dust particles contained in air of workplace, rather than groundless selective isolation of its separate fractions. The standard is set for specifying technical regulations in extracting branches, processing industry, machinery, technologic processes with dust releases.

[On further improvement of sanitary legislation in prevention of diseases related to dust].

The author suggests merger of work condition classes in a classification used by Russian Consumer Protection Board to evaluate work condition by jeopardy and to certify work places in contact with primarily fibrogenic aerosols (P 2.2.2006-05, table 3, p 14)--increasing space of differences between the classes by MAC and dust load.

[Preliminary and periodic medical examinations of asbestos production workers].

The article covers general principles of health care for workers in various industries associated with contact to dust containing asbestos. The authors present main requirements of legal papers basing concepts that determine role of employers, trade unions, workers and medical officers in creation and maintenance of safe work conditions, in establishment of prophylactic, therapeutic and rehabilitation measures.

[Clinico-roentgenological and occupational correlations as a method of revealing the dose-effect dependence in the development of chrysotile-asbestos fibrosis].

For understanding up-to-date situation with fibrosis caused by chrysotile-asbestos, the authors conducted X-ray and hygienic studies in 2 enterprises extracting and enriching asbestos--"Tuvaasbest" JSC and "Orenbourgasbest" JSC. Authors followed correlation between diffuse pulmonary changes and length of service, dust load and cumulative exposure dose of respirable fibers. The strongest correlation was demonstrated for dust load.
