Influence of hazardous work conditions of chemical production on health state of the aged workers. When compared with the group aged under 45 years, prevalence of nervous, cardiovascular and locomotor diseases is 1.5-4 times higher in workers aged over 45 and engaged into main occupations (device operators, operators, fitters) in production of organic glass, dichloroethane, polyurethane foam and subjected continuously to chemicals 2 and more times exceeding MAC. The authors suggest ways to reduce risk of occupationally mediated diseases in aged workers presenting 30-60% of the workshop staffers in the industries studied.
