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 Breathe Life 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.
Discover how humans are affected by air pollution in the graphic: 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 (O), benzo(a)pyrene (Ba P) and suspended particulate matter (PM).
It has been proven that air quality affects human health.
Living in a pollution-free environment signifies a better quality of life, but do we really know how air pollution 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.
It can be directly emitted, as in smoke from a fire, or it can form in the atmosphere from reactions of gases such as nitrogen oxides.
The size of particles is directly linked to their potential for causing health problems.
