Abstract
Sanitary protection of atmospheric air, which is the most important factor of the external environment, ensuring its quality indicators in accordance with environmental standards is one of the current global problems. While global emissions are declining at this rate, global warming and climate change are having unpredictable consequences. Currently, one of the most dangerous sources for human health is toxic gases emitted by vehicles, in particular, the exhaust gases from vehicles enter the body through the respiratory tract and combine with hemoglobin in red blood cells to form carboxyhemoglobin. In samples that did not meet hygienic requirements, sulfur dioxide was found to be in the second place after dusting. In the analysis of atmospheric air pollution with formaldehyde, it was found that all samples met the hygienic requirements.
