Air Environment

The air environment is one of the most important components of the human environment. It represents a certain volume of ambient air, the properties and composition of which influence human physiological processes and can be subject to hygienic regulation.

The air environment consists of many components, such as oxygen, carbon dioxide, nitrogen, various gases and aerosols. These components can have both positive and negative effects on human health. For example, oxygen is necessary for breathing, but in excess it can lead to oxygen starvation. Carbon dioxide is also important for health as it is involved in the process of respiration. However, its excess can lead to high blood pressure and other health problems.

Hygienic standards for the air environment are established taking into account human needs for oxygen, carbon dioxide and other components. They determine the permissible concentration levels of these substances in the air, as well as their distribution throughout the territory of a populated area or industrial facility. Standards may vary depending on the purpose of the room, its functional use, as well as the time of day.

Monitoring the state of the air environment is carried out using special instruments and methods. For example, oxygen meters are used to determine oxygen levels, and gas analyzers are used to measure carbon dioxide concentrations. Research is also being carried out to determine the content of harmful substances in the air.

It is important to note that the air environment can be polluted by various substances, such as dust, smoke, chemical vapors, microorganisms, etc. This can lead to various diseases, such as allergies, bronchial asthma, respiratory diseases, etc. To prevent air pollution, it is necessary to carry out air cleaning and filtration measures.

In general, the air environment plays an important role in human life and requires constant monitoring and care. Compliance with hygiene standards and carrying out air purification measures are necessary conditions for maintaining human health and maintaining a comfortable living environment.

The air environment is one of the most important components of the human environment. It includes the air around us, its properties and composition. The air environment can be divided into three main groups - atmospheric (surrounding us), intranasal and intrathoracic. Air mixtures in both environments consist mainly of nitrogen (78%) and oxygen (21%). Compared to other media, the nitrogen concentration in the air is higher and the oxygen concentration is lower. This is due to the fact that living organisms do not emit or absorb oxygen or other gases; they exchange them with the environment. Nitrogen, which is absorbed when air is inhaled, is slowly eliminated from the body through the lungs. In addition to nitrogen and oxygen, the air contains small amounts of other gases, such as carbon dioxide, argon, neon, etc. In some cases, minor concentrations of these gases can affect human health.

In addition to nitrogen gas, water vapor, dust, smoke particles, wool and hair, microbes (bacteria, fungi) and viruses (for example, bacteriophages, HIV, coronaviruses) can be released in the air. Temperature in most cases depends on
