Objective: to study concentrations of anthropogenic air pollutants on streets with different traffic load and prevalence of laryngotracheitis (LT) among children residing on those streets. Material and methods. We have analyzed the quality of free air on streets with different traffic density in Vinnytsya during 2000-2003. We have studied the concentrations of suspended matters with the content of silicon dioxide less than 20 %, sulfur dioxide, carbon dioxide, and nitrogen dioxide. We have analyzed the frequency of LT cases (1-3 episodes of the disease) and recurrent LT (4 or more episodes of the disease) among children under 14 residing on the streets with different traffic load. Results. The indices of the average and maximum concentrations of free air pollutants on the streets with high traffic density significantly exceeded those on the streets with low traffic density. The prevalence of LT and recurrent LT was significantly higher on the streets with high traffic load. We have found a connection between the prevalence of LT among children, traffic density and concentrations of free air pollutants. The connection between the prevalence of LT and the concentration of nitrogen dioxide has turned out to be the strongest. Conclusion. The prevalence of LT in children is related to traffic load and concentrations of anthropogenic free air pollutants.
