Is air pollution a health risk factor?
Breathing polluted air has long been recognized as increasing a person’s chances of developing heart dis-ease, chronic respiratory diseases, lung infections, and cancer. In 2017, air pollution was the fifth highest mortality risk factor globally and was associated with about 4.9 million deaths and 147 million years of healthy life lost (Figure 1).
What are air pollution indicators?
Several toxic metals, such as lead, can also be con-sidered as air pollution indicators, even if levels of lead have decreased considerably. Moreover, emissions of greenhouse effect gases, such as CO2 or CH4, are also monitored because of their detrimental effects on the environment.
What is air pollution?
Air pollution is the contamination of the indoor or outdoor air by a range of gasses and solids that modify its natural characteristics. Key health-harmful pollutants include particulate matter (PM2.5 and PM10) 1 , carbon monoxide (CO), ozone (O3), black carbon (BC), sulfur dioxide and nitrogen oxides (NOx).
What happens if air pollution levels are above who guidelines?
When people are exposed to air pollution levels above the WHO guideline levels, they are at increased risk of health impacts, in particular cardiovascular and respiratory diseases and lung cancer. The current air quality (for PM) can be informed through the following.
Educational aims
To provide a thorough presentation of sources, dispersion and transformation of major air pol-lutants. To describe the health effects of these air pollutants. To explain the differences between emissions, immissions, exposure and absorbed dose. To help readers to understand what is at stake in the topical scientific and political debate on air
Summary
Air pollution, particularly in urban areas, constitutes a public health concern, as it has a harmful effect on the health, survival and activities of humans and other living organ-isms. Here, the main types of air pollution commonly found in urban environments are pre-sented, along with their sources, levels of emissions, mechanisms of dispersion,
Human-made sources
In urban areas, most air pollution comes from human-made sources. Such sources can be classi-fied as either mobile (cars, trucks, air planes, marine engines, etc.) or point source (factories, electric power plants, etc.). To date, road traffic constitutes the major source of air pollution in the large cities of indus-trialised countries. Combustion
Absorbed dose = immissions x duration x pulmonary ventilation
The concentrations (=immission) of pollu-tants in the air: outdoor concentrations of air pollutants are different from indoor concentra-tions, for example. Outdoor pollutants can also affect indoor air, although the indoor environ-ment has its own peculiar pollution (building materials, cigarette smoke, air conditioners, photocopiers, etc.). The du

Conclusion
Air pollution and specifically urban air pollution remain worrying concerns. Indeed, exposure to air pollutants can lead to an increase not only in mor-bidity but also in mortality. Even if important progress was made in order to reduce emissions of industrial sources, with a substantial decrease in SO2 concentrations, road traffic has become the f
Suggested answers
Emission of air pollutants from human-made or natural sources is the first stage in the cycle of air pollution. Both dispersion and transformation of air pollutants are the following stages. Immission(=concentration in the ambient air) is the fourth stage, which results from the three pre-vious stages. The last stage consists of depositionof air po
