New WHO Global Air Quality Guidelines aim to save millions of lives from air pollution
"Air pollution is one of the biggest environmental threats to human health, alongside climate change. New guidelines provide clear evidence of the damage air pollution inflicts on human health, at even lower concentrations than previously understood."
"Global assessments of ambient air pollution alone suggest hundreds of millions of healthy life years of life lost, with the greatest attributable disease burden seen in low and middle-income countries. The more exposed to air pollution they are, the greater the health impact, particularly on individuals with chronic conditions (such as asthma, chronic obstructive pulmonary disease, and heart disease), as well as older people, children and pregnant women."
The WHO have this week changed their guidance on air quality reducing the target from 10 µg/m3 to 5 µg/m3.
"The recommendation is an annual PM 2.5 AQG (Air Quality Guideline) level of 5 µg/m3."
