[The incidence of paraprofessional diseases in employees of the Research Institute of Ferrous Metallurgy in Kremikovtsi].

The health status of 200 workers from the Institute for Ferrous Metallurgy is studied in view of the harmful effect of the unfavourable factors of the working environment (noise, microclimate, toxic aerosols, gases and vapours). Internal examinations are also performed. A number of laboratory indices are determined in order to assess the liver and kidney functions. A complete blood test and lipid metabolism are examined. Lead and manganese are determined in blood by atomic-absorption spectrophotometry. In 23.5% of the examined are established data for arterial hypertension; with diseases of the gastric-intestinal tract are 22%. The influence of the toxic aerosols and the nervous and psychic loading of the examined workers on the higher prevalence of the paraoccupational diseases are discussed.
