Assessment of the aerogenic risk in adolescent boys at various levels of physical activity

Introdution. Aerogenic exposure to chemicals can contribute to the formation of violations of the main regulatory systems of the body. The aim is to assess the aerogenic risk to the health in adolescent boys at various levels of physical activity. Materials and methods. The content of chemicals in the air of sports halls of general education and sports schools was assessed by single samples, the risk was calculated from the average values of samples taken over 1 hour. The risk is calculated for young 13–17 years boys, taking into account somatometric indicators, the intensity of physical activity. Results. Somatometric indicators of adolescents with moderate and intense levels of activity corresponded to the age norm. The concentrations of suspended solids, sulfur dioxide and nitrogen, formaldehyde in the air of sports halls met the hygienic standards. An aerogenic risk at a moderate level of activity corresponded to hazard index (HI) = 1.5–1.9 at rest, HI = 1.9–2.3 after exercise; intensive level – HI=2.1–4 and HI=3.9–7, respectively. The value of HI at rest and after exercise by 57–58.9% is determined by the content of suspended solids, including PM2.5 = 30-32%, PM10 = 25-26.9%. Limitations of the study are due to the fact that when assessing the hazard index, not all chemicals that may be present in the air of sports facilities are taken into account. Conclusion. The study points to the need to control chemicals in the air of sports facilities and study the effect of chemicals on the state of the leading systems of adolescents, taking into account the level of physical activity.
