[The characteristic state of health of ammonia nitrate producing workers].

The workers producing ammonia nitrate have professional contact with ammonia nitrate aerosol and nitrogenous gases. The state of health of ammonia producing workers has been examined. The morbidity, the therapeutic, neurological and laryngeal status have been inspected. Electrocardiography and examination by peak flow meter by Wotchall has been conducted. Peripheral blood test and radiography of backbone has been carried out as been required. It has been estimated that the illnesses of respiratory apparatus and musculoskeletal system predominate in the morbidity structure. The clinical examination of the workers with basic professions of the production of ammonia nitrate shows the frequent cases of chronic bronchitis and radiculoneuropathy. The results of function study show the damage of airways, the myocardiodystrophy and the changes of T wave. The nitrogen containing particulate pollutants that irritate respiratory systems and hard manual labor at these working places determine these illnesses. This fact corresponds with the hygiene and sanitary conditions of labor at major working places of production. This confirms the major role of occupational-productional factors in the etiology of these pathological conditions. In order to prevent the remote structural lesion of respiratory and cardiovascular systems it is required to amend the functional damage. On the basis of carefully performed study a complex of recreation measures has been carried out in order to improve the service conditions.
