90% of the world’s population sucks dirty air and kills millions of people
According to foreign media reports, the World Health Organization recently said that nine out of every 10 people in the world inhale low-quality air, and more than 6 million deaths each year are related to air pollution.
According to reports, the WHO report released on September 27 pointed out that as many as 92% of the people on the planet live in areas with air pollution levels exceeding the minimum set by WHO. It is worth noting that the city’s air pollution is the most serious, but the rural air is not as good as many people think.
According to the report, nearly 90% of air pollution deaths occurred in low- and middle-income countries, mainly in Southeast Asia and Western Pacific countries such as Malaysia and Vietnam.
The data show that more than 6 million deaths per year worldwide are related to exposure to outdoor or indoor air pollution, while outdoor air pollution values are higher than indoor pollution values, with more than 3 million people dying from outdoor air pollution each year.
However, the lethality of indoor air pollution is equally serious, especially in some poorer developing countries, where many families still cooking with coal face such threats.
Naira, director of the WHO Department of Public Health and Environment, said in a statement that air quality in poor countries is worse than in developed countries, but air pollution “almost inevitably affects every social class in all countries of the world”.
Naira urged governments to act quickly to address air pollution by reducing vehicles on the road, improving waste management practices, and promoting clean fuel cooking.
When talking about the measures taken by countries around the world to deal with air pollution, Dora, coordinator of the WHO Department of Public Health and Environment, said that some existing measures such as releasing air forecasts, avoiding going out or wearing masks are not too big. effect.
There is no conclusive evidence to date that masks can effectively block dirty air.
Take Beijing as an example. Although the city sometimes provides air quality forecasts for the public, Dora believes that the actual help of these forecasts is not great for people who live there for a long time and are in the air of substandard quality.
As for the practice of urging the people to stay indoors during the particularly serious days, he believes that this is actually useless. Dora also said that WHO has so far not had any solid evidence that masks are an effective way to block dirty air.
The report’s data comes from more than 3,000 human settlements around the world, mainly targeting hazardous particulates with a diameter of less than 2.5 microns in the air, namely PM2.5. These fine suspended particles contain toxic substances such as sulfate and black carbon, which can penetrate deep into the lungs of the human body or the cardiovascular system.
According to the WHO air quality standards, the annual average of PM2.5 should be less than 10 micrograms per cubic meter, and the air quality above this level is unqualified.
According to another report released by WHO in May this year, 80% of the population living in cities around the world infiltrated polluted air every day. In poor countries, more than 98% of the urban population inhaled polluted air.
