The negative impact of polluted air is subjected to 92% of the inhabitants of the Earth, said WHO, presenting new interactive maps, whith marked areas inside of countries that have low air quality.
Previously, the WHO has not published enough details on air pollution separated for countries. The model was built on the basis of information received from the satellites and more than 3,000 land-based monitoring stations located in both rural and urban areas. Country indicators of air pollution were analyzed, taking into account population size and levels of air pollution, and using the grid in increments of about 10 km by 10 km.
Air pollution is responsible for about 3 million deaths each year, according to the WHO material. Moreover, indoor air pollution is also dangerous. In 2012, air pollution inside and outside the premises caused, estimated at about 6.5 million.deaths (11.6% of the total). About 90% of deaths related to air pollution are recorded in the low- and middle-income countries, with almost two out of three – in the South-East Asia and the Western Pacific.
Earlier the WHO estimated that due to air and soil pollution, chemicals, climate change, and UV radiation we have more than 100 different diseases and injuries. The organization stressed that non-communicable diseases (cardiovascular and respiratory diseases, cancer) accounted for two thirds of all deaths caused by a stay in an unhealthy environment.
The main sources of air pollution include inefficient modes of transport, burning fuel and garbage in households, coal-fired powerplants and the work of industrial enterprises. However, human activity – is not the only cause of air pollution. For example, it can be affected by dust storms, particularly in regions that are close to the deserts.
