[Evaluation of ambient air pollution on children's morbidity with acute respiratory infections of the upper airway].

A relationship of ambient air pollution in the towns of Almetyevsk and Kazan to acute respiratory infection of the upper airways (ARIUA) in children was examined. Higher atmospheric pollution was found to cause an increase in the incidence of ARIUA. The correlation ratios for all the nosological entities studied ranged from 0.71 to 0.92, their mean errors were 0.01-0.29. There was a significant combined effect of sulfur dioxide and carbon oxide (9.9%, p < 0.01), that of sulfur dioxide and dust (8.1%, p < 0.001). The findings serve as the basis for elaboration of measures to reduce environmental pollution.
