[Occupational risk for development of respiratory diseases in foundry shop workers at machinery industries].
The paper provides the results of assessment of prior and posterior occupational risks and those of questionnaire analysis in foundry shop workers from machinery enterprises. According to the data of attestation of job places, the working conditions of major foundry occupations were ascertained to correspond to class 3, grades 1 to 3. ⋯ According to the results of a questionnaire survey, more than half of the workers sought medical advice for bronchopulmonary pathology. Determination of whether there is, in terms of the etiological share, a cause-and-effect relationship between RDs and working conditions has shown that the occupation was highly responsible, which suggests that harmful industrial factors make a considerable contribution to the development of RDs in the workers of the enterprises under study.
