[MEDICAL AND PREVENTIVE MEASURES FOR REDUCING CHEMICAL OCCUPATIONAL RISKS IN THE PRODUCTION OF TITANIUM ALLOYS].

An innovative approach in the prevention and rehabilitation of workers employed in the production of titanium alloys envisages the implementation of targeted multi-stage rehabilitation measures in groups with high occupational risk.

[Hygienic evaluation of the effects of vibration and arsenic in miners engaged in extraction of arsenic-containing ore]. / Gigienicheskaia otsenka vozdeistviia vibratsii i mysh'iaka na gornorabochikh, zaniatykh dobychei mysh'iaksoderzhashchei rudy.

Hygienic evaluation covered work conditions on 4 gold mines including 3 ones for gold and arsenic and one "arsenic-free". The mines demonstrated similar occupational factors, but differed in arsenic content of the ore extracted and therefore in arsenic concentrations in air of the workplaces. Miners engaged into extraction of the arsenic-containing ore, especially those exposed to vibration and arsenic concentrations over the MAC, manifest extensive arsenic accumulation in the hair and excretion with the urine, higher morbidity with transitory disablement, more prevalent vibration disease and mortality with malignancies. Vibration disease in those subject has more severe course, serious vegetative and sensory polyneuropathy, that is believed to result from co-action of vibration and arsenic.

[Clinical and hygienic evaluation of the combined effect of vibration and fluoride in humans]. / Kliniko-gigienicheskaia otsenka sochetannogo deistviia na organizm vibratsii i ftora.

Hygienic evaluation of work conditions and clinical examination of workers in fluoride mines proved vibration disease to be the prevalent occupational entity in those employees. Caused by joint effects of vibration and fluor, the clinical signs in this context demonstrate short development, occupational disablement and possible connection with fluorosis. Joint effects of vibration and calcium fluoride vs. influence of the isolated hazards show more compromised functions and changes of fluor kinetics in the body.

[Primary and secondary prophylaxis of vibration disease caused by local vibration in miners]. / Pervichnaia i vtorichnaia profilaktika vibratsionnoi bolezni ot vozdeistviia lokal'noi vibratsii u gornorabochikh.

The article contains data on complex balneotherapy of vibration disease caused by local vibration in high risk group (miners exposed to vibration), that help to justify use of means for primary and secondary prevention of vibration disease.

[Occupational medicine in aluminum and copper alloy production]. / Meditsina truda v proizvodstve aliuminievykh i mednykh splavov.

Workers engaged into aluminum alloys production demonstrated high prevalence of occupational respiratory diseases caused by dust--pneumoconiosis and dust bronchitis, workers of copper alloys production were diagnosed as having early stage of chronic lead intoxication.

[Dust as a factor in crystalline silicon production]. / Pylevoi faktor v proizvodstve kristallicheskogo kremniia.

Up-to-date crystalline silicon production is characterized by such leading occupational hazards as higher level of dust with complicated chemical composition, aerosols that vary with technology and derive from disintegration of silica, crystalline silicon or condensation of silica. Experiments comparing prevalence of diseases caused by silica and crystalline silicon dusts in acute and chronic intratracheal administration and inhalation identified crystalline silicon as moderately fibrogenic and specified its MAC at 4 mg/m3 in the air of workplace.

[Priority topics of industrial medicine in production and processing of nonferrous metals alloys]. / Prioritetnye voprosy meditsiny truda v proizvodstve i obrabotke splavov tsvetnykh metallov.

The authors present general characteristics of nonferrous metals alloys production: work conditions, health state of workers, main directions to make healthier work conditions.
