[Influence of environmental chemical factors on the risk for different types of pulmonary tuberculosis].

The quantitative relationships found between the morbidity rates for different types of pulmonary tuberculosis may be a factor that contributes to increased tuberculosis morbidity rates in the past decades. In addition to a rise in morbidity rates, there was an upward tendency for new cases to have destructive and bacillary forms. The possible causes promoting this clinical presentation of pulmonary tuberculosis under the present-day conditions should include atmospheric pollution with man-made chemicals.

[Effect of chemical environmental factors on risk for various forms of pulmonary tuberculosis].

The correlation-regression analysis, including that on an EC-1036 computer, was used to examine the quantitative dependence of tuberculosis morbidity on the man-made pollutants of the air. Prognosis of various forms of tuberculosis have been worked out. Out of the atmospheric pollutants, carbon dioxide heads the list, sulfur dioxide ranks next, the less effects are produced by nitrogen dioxide.
