Ecology and health: environmental effects on the human body

I. Air: Breathing of life and the threat of diseases

A. The composition of atmospheric air and its value for health:

  1. Oxygen (O2): The fundamental element for cellular respiration, providing energy to all life processes. Its deficiency (hypoxia) leads to damage to the brain, heart and other organs, especially sensitive to oxygen starvation. Highland areas, smoky city centers, closed rooms with poor ventilation are examples of places with possible hypoxia. Chronic hypoxia can contribute to the development of chronic diseases of the lungs and cardiovascular system.
  2. Nitrogen (n2): The main component of the atmosphere inert in normal conditions. Participates in the cycle of substances necessary for the life of plants and, indirectly, animals and humans. In high pressure conditions (for example, with deep -sea dives), nitrogen can cause a narcotic effect, known as “nitrogen intoxication”.
  3. Carbon dioxide (CO2): It is necessary for plant photosynthesis. In the human body, it is a product of cellular respiration and a regulator of the acid-base balance of the blood. The increased concentration of CO2 in the air causes an increase in breathing, headache and fatigue. Especially dangerous in poorly ventilated rooms.
  4. Inert gas (argon, neon, helium, crypton, xenon): They practically do not participate in biochemical processes, but are used in medicine (helium for respiratory mixtures).
  5. Water vapor (H2O): Regulates air humidity, important for the normal functioning of the respiratory tract and skin. Excessive humidity contributes to the development of mold and fungi, and insufficient – drying out the mucous membranes and skin.
