The effects of air pollution on human health

Air pollution, especially in urban environments, damages multiple organs and functions of the human body. Discover it in this infographic

The effects of air pollution on human health

Air quality significantly affects the lives of people. Living in a pollution-free environment signifies a better quality of life, but do we really know how atmospheric contamination affects us and which parts of our bodies are damaged by each kind of polluting particle?

Air pollution causes around seven million deaths a year worldwide. Growth and concentration of the population in cities, as well as the way in which we consume energy in urban areas through transport or heating and air conditioning systems, among others, result in the emission of huge quantities of gases that are harmful to our health.

Main causes of air pollution

Emissions from different transport modes, the burning of fossil fuels, industrial production, forest fires, aerosol use and radiation fare some of the main causes of air pollution.

Such sources of emissions liberate gases and substances that are toxic for human beings, the most harmful of which are: tropospheric ozone (O3), sulphur dioxide (SO2), nitrogen dioxide (NO2), benzo(a)pyrene (BaP) and suspended particulate matter (PM).

How does air pollution affect our health?

Our physical and psychological wellbeing is affected differently by the kind of air pollution we are exposed to. There are many organs and bodily functions that can be harmed, the consequences including:

  • Respiratory diseases
  • Cardiovascular damage
  • Fatigue, headaches and anxiety
  • Irritation of the eyes, nose and throat
  • Damage to reproductive organs
  • Harm to the liver, spleen and blood
  • Nervous system damage.

Urban populations are more exposed to suffer the effects of air pollution and, in this context, people who are already ill are particularly vulnerable, as are children and the elderly.

How to tackle air pollution

To alleviate the negative effects of atmospheric pollution on health, the World Health Organization (WHO) and the Climate and Clean Air Coalition (CCAC) – made up of the United Nations Environment Programme (UNEP) and 54 nations, among other agencies – launched the BreatheLife initiative.

This is a program that aims to “aims to mobilize cities and individuals to protect our health and our planet from the effects of air pollution” and which has fixed the objective of cutting by half the number of deaths linked to air pollution before 2030.

Actions will be local and focused on improving transport, waste management, indoor air quality, energy supply, industry, food and agriculture.
