New WHO has issued new Global Air Quality Guidelines (AQGs) that reduce levels of key air pollutants, some of which also contribute to climate change. Recommended 2021 AQG levels compared to 2005 air quality guidelines. When action is taken on these classical pollutants—particulate matter (PM), ozone (O?), Source: WHO.

Daily exposure to ground level ozone in cities worldwide is associated with an increased risk of death, according to the largest study of its kind, published in an open-access paper in The BMJ. Ground level ozone is a highly reactive gas commonly found in urban and suburban environments, formed when pollutants react in sunlight.

The European Environment Agency’s (EEA’s) “ Air quality in Europe — 2019 report ” shows that almost all Europeans living in cities are still exposed to air pollution levels that exceed the health-based air quality guidelines (AQGs) set by the World Health Organization (WHO). About 8% of the urban population in the EU-28 was exposed to PM 2.5

In 2013, 87% of the world’s population lived in areas exceeding the World Health Organization (WHO) Air Quality Guideline of 10 μg/m 3 PM 2.5 Additionally, the study found that the population-weighted mean concentrations of ozone increased globally by 8.9% An additional 217,000 deaths were attributable to long-term ozone exposure.

and tropospheric ozone. Ozone accounted for about 472,000 early deaths in 2017. More than 90% of people worldwide live in areas exceeding the WHO Guideline for healthy air. Numbers of deaths attributable to air pollution in countries around the world in 2017. Ambient PM 2.5 accounted for 2.9 million deaths.

As a result of these findings, the researchers say that national governments and international agencies must take urgent action to reduce air pollution, including re-evaluating legislation on air quality and lowering the EU’s current limits on the annual average levels of air pollution to match the WHO guidelines. in the EU is 25 ?g/m
