Many cities in the world have a high level of air pollution, as it increases the risk of patients with respiratory diseases, asthma, cardiovascular and cancer. Air pollution has been spreading in more industrialized and more densely populated cities, gradually has been manifesting in different geographical areas of the world, which reflects that it is necessary to seek short and long term solutions that reduce the effects created. The large industrial growth and the continuous increase of automobiles are factors that contribute to a great extent to raise the contamination.


Populations in Asia, the Middle East and Africa live in cities with a high degree of pollution that do not comply with WHO standards, recommending a concentration in the air of no more than 25 micrograms per cubic meter. In developing countries, particulate levels in the air increase relative to economic and industrial growth and the continuous increase of cars.

More than 90% of the world’s population lives in areas with dangerous levels of pollution, according to studies conducted by the World Health Organization, highlighting the increasing risk of air pollution affecting different demographic groups in the World, about 7 million people die each year from diseases related to air pollution, according to the WHO.

A research group on the effects of air pollution on health, have discovered that small amounts of polluted air influences the health of people subjected to the effects of that environment and increases the risk of patients with respiratory diseases, asthma , Cardiovascular and cancer patients.

In the study more than 3,000 cities and towns around the world report high levels of air pollution, but some geographical areas are more affected than others. The northern part of China is the most affected by pollution and is represented by the cities of Beijing, Tianjin and the provinces of Hebei and Shanxi, in the city of Beijing have sometimes had a contamination of 700 micrograms of gases Greenhouse per cubic meter of air. Los Angeles in the USA, London and Paris in the European Union and Senegal in Africa are regions with pollution rates well above the recommended values. Air pollution by particulate matter has declined in the last decades in more developed countries, although it remains present at dangerous levels.

In the case of the city of Shenyang, northeast China, the atmosphere is so charged that the visibility is reduced to one hundred meters, in this city has begun to force companies to replace coal with natural gas, but the peaks of pollution are still frequent and hospital consultations are full of people with respiratory problems. Many regions of China have been suffering from high levels of air pollution for many days, limiting the circulation of vehicles on the streets, halting construction work and keeping children inside buildings.

Over the past 20 years, China has maintained great economic and industrial development but has greatly deteriorated air and water quality. In many Chinese cities the levels of pollutant particles in the air surpass the levels of pollution that in Europe would be considered highly dangerous, so that a thick fog appears that is becoming common. As air pollution has spread through more industrialized and more densely populated cities, it has gradually become manifest in different geographical areas of the world, reflecting the need to take the necessary environmental measures to improve the quality of life in the planet.

Air pollution by greenhouse gases accelerates global warming and causes an increase in temperature in the air and the oceans, resulting in great instability of weather patterns, the melting and unbalance of natural forces of the planet, so it is necessary to look for short- and long-term solutions that reduce the effects created.
