Working conditions and health status of workers engaged in the production of zinc compounds]

It was established that industrial shops engaged in zinc compounds' processing were characterized by considerable temperature shifts, relative humidity and air motion changes. In drying and packing shops, concentrations of the final product dusts were established at 0.8-2 mg/m3. The major occupational pathology was constituted by skin and upper respiratory tract diseases, including allergic and contact dermatitis, chronic pharyngitis, tonsillitis and rhinitis. Blood tests revealed B-lymphocytes: increases, circulating immune complexes and considerable levels of lymphocytic spontaneous blastotransformations. Erythrocytic acidic hemolysis was markedly changed, which proved disbalances in the system of red blood.     

Hygienic characteristics of work conditions and health status of workers engaged in cobalt salt production

It was established that the major hazardous substances in cobalt acetate, chloride, nitrate and sulphate processing shops were the finished product's dusts (disintegration aerosol) in concentrations from 0.05 to 53 mg/m3 depending on the stage of the technological process. An analysis of morbidity with temporary disability and the rate of the workers' appliance for medical advice showed, among the major groups of industrial workers, particular prevalence of the upper respiratory tract diseases (rhinitis, pharyngitis, laryngitis) and the signs of irritation of the mucous in the eyes. ECG examinations revealed marked changes of varying severity in the myocardium among 40-58 percent of the workers in major professions.     

Labor conditions and health status of the workers engaged in the production of inorganic salts of manganese

It was established that the major hazardous factor in nitrate, sulphate and manganese basic carbonate processing shops was the dust of the final product. Upper respiratory tract (catarrhal, subatrophic rhinitis, pharyngitis, laryngitis), skin (allergic and contact dermatitis) and cardiac disorders were specified as the predominant pathology among manganese compounds processing shop workers. Mineral exchange disorders, lowered glucose content in the blood and violation in the acid persistence of the erythrocytes were revealed through medical examinations.     

Working conditions and morbidity among workers engaged in the production of vegetable oil

A hygienic model for controlling some indices of their health is scientifically substantiated on the basis of the data of sanitary evaluation of working conditions and those of study of morbidity with temporary disability in workers engaged at the vegetable oil-producing enterprises. The practical use of a package of preventive and health-promoting measures caused a 7.2-30.8% reduction in the incidence of diseases with temporary disability in the workers.
