Summary:
Abstract. Objective: based on an assessment of the inhalation risk to the health of children involved in sports, to substantiate the need to improve the control of chemical air pollution in sports halls. Material and methods. The quality of the air environment of open and closed sports facilities was evaluated in comparison with 0.8 of the current one-time maximum permissible concentrations (MPC). The routes of exposure to pollutants from atmospheric air and the air environment of sports, residential and school premises are considered. The assessment of the general toxic risk was carried out in accordance with R 2.1.10.1920-04. Results. In the air of outdoor sports grounds there were registered contents exceeding maximum single MPC: within the city limits — N02, NO, S02, suspended substances, formaldehyde; outside the city— N02. In the air of the indoor ice arena, an excess 0.8 maximum single MPC of formaldehyde. In the martial arts halls the content of C02 was 1500.5±444.9 ppm. Taking into account the daily route of children engaged in sports in the halls of children's and youth sports school, the value of the hazard index (Hlch) =4.9, and for those who are engaged in ice arenas Hlch=5.7. It is possible to develop negative effects of the respiratory system and immunity. Conclusion. High breathing rate during sports can lead to health risks, even if the maximum concentration limit is observed. The current documents do not reflect the criteria that regulate the impact of air pollution in the training process. It is necessary to revise the system of hygienic regulation of sports environment factors for children involved in physical culture and sports.
