Keys to understand how ozone affects us Keys to understand how ozone affects us

Low ozone is one of the atmospheric contaminants that, according to its concentration, can generate health risks.

The ozone at floor level, which should not be confused with the layer of ozone in the higher atmosphere, forms when the contaminants from automobiles, factories and other sources chemically react with sun light. It is the main component of smog, as confirmed by the United States Environmental Protection Agency.

The World Health Organization (WHO), in its statement about the Quality of air and health in 2018, confirms that the higher levels of ozone are recorded during the periods of sunny weather and that the excess of ozone in the air can produce significant adverse effects on human health, such as respiratory problems, provoke asthma, reduce pulmonary function and give rise to lung diseases.

The Colombian Ministry of Health defines atmospheric contamination as the presence in the air of a foreign substance or an important variation in the proportion of its components, susceptible of provoking damaging effects on the health and the environment. According to estimates made in 2016, says the WHO, this contamination in cities and rural areas around the world provokes 4.2 million of premature deaths each year.

Air and health recommendations from the Colombian Ministry of Health:

  • Making preventive maintenance to automobiles.
  • Using cleaner transportation means.
  • Avoiding burning garbage and tires.
  • Reducing the consumption of electricity, which will contribute to decreasing the emissions of contaminants and particles.
  • Decreasing the use of aromatizing and perfuming aerosols in closed spaces.
  • Avoiding practicing physical activities closet o locations with high concentration of contaminants.
