WHO has tightened the Air Quality guidelines, for the first time since 2005. The new WHO Global Air Quality Guidelines (AQGs) provide a clear indication of the damage that air pollution inflicts on human health, now at even lower concentrations than previously understood. Air pollution causes about 7 million premature deaths each year.
The new guidelines recommend air quality levels for six pollutants, where evidence has advanced the most on health effects from exposure. Two types of particulate matter known as PM 2.5 and PM 10, Ozone (O₃), Nitrogen dioxide (NO₂), Sulfur dioxide (SO₂), and Carbon monoxide (CO). According to the new limits, average annual PM2.5 concentrations should be no higher than 5 micrograms per cubic meter.
