The authors estimated fluorine compounds content of workplace air in electrolysis workshops of aluminium production, for various electrolysis technologies. The data cover results of physical and chemical analysis and material constitution of produced toxic dust complexes, urinary excretion levels of fluorine ion and fluorides accumulation in hair of aluminium production workers.

The features of development of the skin vessels lesions in 550 aluminum production workers have been investigated. The high prevalence of these disorders have been revealed in anode-operators and cell-operators, 49, 3 and 26.0% of workers, respectively. The regularity and staging of the development of this abnormity have been established, etiology, pathogenesis and clinical significance of those remain unknown.

Multi-year follow-up of 358 workers of aluminum pot rooms, including 165 individuals suffering from fluorosis, has shown significant changes in the clinical picture of the chronic occupational fluorine intoxication, developed under modern conditions of production, at lower concentrations of fluorine compounds in the air of working area. In this connection, the pathology of the musculoskeletal system plays the dominating role in this clinical picture and has the large variability of combinations of the individual sections destructions of the bone tissue. The main criterion to establish the phase of the disease is still the number and severity of the signs of this destruction. The visceral pathology in contemporary production circumstances is registered with less frequency and loses a number of the previously described clinical manifestations, however, is still of some importance to identify the early signs of the disease and to prevent the dental fluorosis on time.

The aim of this research is to investigate the role of the occupational risks in the development of pain syndromes of the locomotor system in workers employed in basic workplaces at aluminum potrooms, basing on the periodic health screenings data. It has been determined that working under the conditions of toxical fluorides-related exposure and athletic overexertion increases the risk of the upper arm pain syndrome development 4.3 fold. The maximum relative risk (108.2) has been revealed in the workers of such kind of professions having the length of employment upper 20 years and suffering simultaneously from cervical osteochondrosis and pulmonary diseases.

Volunteers were subjected to the effect of electrolysis oxygen received from different moisture materials in a system with hard polymer electrolyte. Results indicate that a 30-minute inhalation of electrolysis gaseous oxygen in mixture with gaseous nitrogen (1:4) produced no negative effect on the vital systems of the human body. Electrolysis gaseous oxygen is recommended for breathing and medical purposes.
