[The methodological aspects of identifying the etiological significance of anthropogenic pollution in the genesis of chronic bronchitis].

The paper is concerned with multifactorial assessment of the air anthropogenic contamination effect on development of chronic nonspecific pulmonary diseases, chronic bronchitis (CB) in particular. Methodological approaches to identify etiological significance of anthropogenic effects in CB genesis include measurements of the air contaminants, calculation of the total contamination index, selection of the study and control territories, analysis of medical documents, conduction of wide-scale medical examinations. CB developing in the conditions of the above contamination is characterized by obstructions, bronchospastic components, other separate or systemic disorders.
