Air pollution


The pollution of the air is a mixture of particles solid and gases found in the air and are not part of normal components. Emissions from automobiles , chemicals from factories, dust , pollen, and mold spores can all become airborne as particles. Some air pollutants are poisonous and inhaling them can increase the chances of different health problems . People with heart or lung disease, older adults and children are at higher risk of getting sick when air pollution occurs. Air pollution is not something that remains static , but, on the contrary, the wind and the different states of the climate work as a means of transport for it to travel from one place to another, affecting everything that enters it. contact with her.


What is air pollution?

Air pollution is that which occurs when a series of toxic gases come into direct contact with gases in the atmosphere , causing a series of damage to the health of both man and animals as well as plants .

Causes of air pollution

The main cause for air pollution is through the burning of different fuels such as coal, oil and gases. When they burn, there is a combustion effect that pollutes the environment. In general , the industrial sector and the different means of transport are mainly responsible for producing significant quantities of these fuels. Other causes that also affect the air are aerosols that leave polluting particles suspended in the air for long periods of time. The garbage misplaced and some restaurants also produce substances that pollute the air circulating. The Atomic radiation is one of the causes that are most tried to be avoided since radioactive particles can remain in the air for a long time, contaminating plants and water , which will later be consumed by humans and can cause cancer and genetic mutations .


Sources of air pollution

Air pollution comes from different sources. Sometimes natural processes such as volcanic eruptions produce a series of particles including ash that produce carbon monoxide. Most of the air pollution problem comes from human hands through industries and vehicles that generate nitrogen oxides, sulfur and carbon monoxide. The aerosols and gases filterable equipment cooling , the paint and other solvents are also sources of contamination.

Effects edit

The effects that air pollution can have are very great when we talk about the direct impact on health. The increase in asthma cases , respiratory difficulties and diseases of this system, produce great problems in breathing . People suffering from cardiovascular diseases are mostly affected by polluted air. In addition to causing different long-term health problems , they can also cause short-term damage when exposed to high levels of pollution that is reflected with burning eyes, eye pain, throat irritation. The carbon monoxide it can lead to chronic fatigue and headaches.


Vehicle smoke contains carbon monoxide, carbon dioxide, and lead. These gases are highly toxic to animals and humans, as they block oxygen transport in the blood and cause anemia. The aerosols filter through the nose into the bronchi and penetrate the lungs. The accumulation of toxins in the air produces acid rain that permanently damages crops, soils and rivers. These toxic agents at the same time are responsible for producing the greenhouse effect. It can produce irreversible changes in the skin of living beings, such as cancer, since the damage done to the ozone layer is capable of allowing access to ultraviolet rays .

Prevention of air pollution

Among the prevention measures that can be applied to avoid contamination are:

  • Reduce the use of public transport.
  • Do not buy products that are not biodegradable.
  • Use pesticides and fertilizers in a rational and controlled way.
  • Avoid using tobacco.
  • No littering in the street.
  • Reduce the use of aerosol cleaners.
  • Educate populations to avoid contamination.


The main types of contamination are:

  • Gaseous pollutants:  carbon dioxide , carbon monoxide, nitrogen oxide and ozone . Tobacco, materials released by volcanoes and industries also fall into this qualification.
  • Aerosols : mixtures of solid or liquid particles that remain suspended as a gas in the atmosphere .

Examples of air pollution

Some examples of air pollution are: means of transport that generate large amounts of smoke and gases that are dangerous to health. The fossil fuels that are used to produce energy. The deforestation indirectly affects of air pollution as to the clearing trees mimes capacity to produce oxygen is removed and removing carbon dioxide.
