[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. The highly determined multiple correlation coefficients suggest that there is a combination of chemical pollutants which can have effects on morbidity due to various types of pulmonary tuberculosis. The calculated multiple determination coefficients are 30.1, 80.2, and 66.1% in disseminated, focal, and fibrocavernous tuberculosis, respectively.
