WHO calls for improved air quality

World Health Organization (WHO) yesterday warned that air quality in many countries around the world has reached a level of harm to human health.

The WHO study is based on an air sample of nearly 1,100 cities, in 91 countries around the world, including capitals and cities with a population of more than 100,000.

WHO estimates that more than 2 million people die each year because of the inhalation of PM10 dust (arising from motorcycles, power plants). PM10 is smaller than 10mm so they easily penetrate into the lungs, go into the blood, cause heart disease, lung cancer, asthma and respiratory infections.

According to the WHO report, the density of PM10 in some cities is up to 300 micrograme in 1m ³ (ug / m ³ ), while the standard is 20 ug / m ³ .

"Air pollution has a big impact on the environment and human health. If we monitor and manage the environment properly, it is possible that the number of people with respiratory disease, heart disease and lung cancer will decrease. "In many countries there is no regulation on air quality , " said Dr. Maria Neira, WHO director.

WHO calls on countries around the world to promote propaganda to raise awareness about risks from air pollution to human health, develop effective policies and closely control the pollution situation in the regions. city.

According to WHO experts, reducing the annual density of PM10 dust from 70 ug / m ³ to 20 ug / m ³ could reduce the mortality rate by air-related diseases.
