According to the United Nations, nearly everyone in the world breathes air that does not meet its air quality guidelines, and it is declaring for more intervention to tackle the use of fossil fuels, which emit contaminants that cause respiratory and blood-flow problems, as well as millions of avoidable deaths each and every year. Over 6,000 cities in 117 countries are now analyzing air quality, but residents are still consuming harmful amounts of small fine particulates and nitrogen dioxide, with individuals in poor and middle-income nations being exposed the most, according to the research. “That’s what we’re saying when we look at the wealth of information, facts, and alternatives available on-air pollution.” “However, too many expenditures continue to be made in filthy surroundings rather than in clean, healthy air,” she remarked. Doctors feel that the inclement weather creates major health problems for people, such as pneumonia and cancer.

The revised air quality dataset is the most comprehensive ever in terms of ground-level ambient air pollution. Since the last update, about 2,000 more cities/human populations have been gathering ground monitoring data for particles in the air, PM10 and/or PM2.5. This is an almost 6-fold increase in submissions since the database’s inception in 2011. Meanwhile, the clinical evidence supporting the harm related to air pollution to the human body is fast expanding, pointing to considerable impairment caused by even low levels of several air contaminants. Small particles, particularly PM2.5, have the ability to penetrate deep into the lungs and into the circulation, causing cardiovascular, cerebrovascular, and respiratory complications. There is growing evidence that particulate matter affects other organs and causes disorders.

WHO: 99% of world's people breathe bad air

“It is intolerable that, after overcoming a pandemic, there are still 7 million unnecessary deaths and numerous avoidable years of good health wasted owing to air pollution,” said Dr. Maria Neira, chief of WHO’s a department of environment, climate change, and health. “Yet, far too many resources continue to be made in a filthy atmosphere rather than in clean, healthy air.” Nitrogen dioxide is mostly produced by human-generated fuel combustion, such as automotive traffic, and is particularly prevalent in metropolitan areas. According to the WHO, exposure has been linked to respiratory diseases such as asthma, as well as symptoms such as coughing, wheezing, and trouble breathing, as well as an increase in hospital and emergency room visits. “We have to prioritize clean energy accessibility for the most vulnerable households, as well as take proactive steps to clean up our industrial base,” she added.
