[Incidence of pyelonephritis on territories with different levels of anthropogenic loading].

Relationship between atmospheric pollution with harmful substances and incidence of pyelonephritis was studied for the populations living in ecologically unfavorable and clean regions of an industrial city. Disease intensity and incidence were significantly higher in polluted regions, the probability of error being no more than p < 0.05-p < 0.001. The correlation between atmospheric nitrogen dioxide concentration and pyelonephritis incidence was the strongest for all years analyzed. Correlation coefficients tend to increase: during the analyzed period they increased from Rxy = 0.42 +/- 0.4 (p < 0.01) to Rxy = 0.64 +/- 0.15 (p < 0.01).
