An epidemiological survey of 2000 Donbass coal miners revealed data on the initial dust bronchitis prevalence and its progress. It was established that the coal miners who work in mines with steep coal strata exhibit higher bronchitis morbidity in comparison with the miners engaged in sloping strata mines. A correlation was established between dust bronchitis prevalence and length of professional service and coal miners' labour specificity. Tobacco smokers displayed a markedly higher percentage of chronic dust bronchitis cases. |
