Complex labour-hygienic studies were carried out on the working environment in divinyl production as well as on the health state of the workers. The leading deleterious factor of the environment are the concentrations of divinyl, hydrocarbons and ammonia above the norms. The latter have been determined by stationary and personal sample collecting. More than half of the workers examined work under labour conditions characterized as "particularly unfavourable" and "dangerous". In comparison with the hygienic characteristic by the middle of 1978-1980, a considerable increase of ammonia concentrations was established. A total of 102 workers have been covered by a complete clinical-laboratory examination. The results have been statistically processed with a view to establishing the correlation between the effect of the deleterious factors of the working environment and the deviations established in the health state of the workers. The following cases could be associated with occupational risk: cases with "positive" and "very likely" chronic ischemic heart disease as well as those with arterial hypertension, gastrointestinal diseases, chronic diseases of upper respiratory pathways with loss of sense of smell to various degrees, the neurological diseases--autonomic-vasal and neurotic syndrome, the cases of contact dermatitis and anemic syndrome.
