INFLUENCE OF MAIN COMPONENTS OF VEHICLE EXHAUST GAS ON HEALTH STATUS OF CHILDREN IN CENTRE OF THE CONSTITUENT TERRITORY OF THE RUSSIAN FEDERATION

The article presents the results of study of the influence of pollution of the atmospheric air in residential areas of the regional center with components of vehicle exhaust gases on the levels of total and primary morbidity on the basis of appealability for medical aid among child population. The purpose of the study was to identify the relationship between the anthropogenic load by the main pollutants entering the air of residential areas with vehicle emissions, and the frequency of total and primary morbidity on the basis of appealability for medical aid among child population. Volumes of specific emissions of the main pollutants that enter the atmosphere with vehicle emissions in some residential areas of the city have been calculated based on monitoring of the traffic intensity in the parts of the traffic network. Data on the morbidity of child population were obtained from the report forms of 16 children's polyclinics of the city for the period 2005-2014. Correlation between the volumes of specific emissions of the main components of automobile exhaust gases and the primary morbidity of child population was studied by method of correlation analysis. Estimation of the statistical reliability of the correlation relationships was carried out on the basis of error of correlation coefficient. The results of the correlation analysis evidence the existence of a statistically reliable relationship between the level of the atmospheric air pollution in the city, the emissions of motor vehicles and the overall and primary morbidity of child population. In particular, a strong direct correlation dependence was found between specific emissions of carbon oxide, hydrocarbons and primary children's morbidity levels according to seeking medical help for diseases of the endocrine system; the correlation coefficients were 0.774 and 0.763 (p<0.001), respectively. In addition, moderate correlation relationships were revealed between the values of the specific emissions of carbon oxide, hydrocarbons, sulfur dioxide and nitrogen dioxide, soot, formaldehyde, benzpyrene entering atmospheric air of residential areas with the exhaust gases of the intra-district automotive transport, and general and primary morbidity by appealability of child population with neoplasms, diseases of the nervous, musculoskeletal systems, chronic pharyngitis and congenital anomalies.
