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." p78, WHO global air quality guidelines.

"Cornwall works towards the national air quality objectives, as set out in the Clean Air Strategy 2019 (DEFRA). More information on how the Council is working to improve air quality in Cornwall is set out in the Clean Air for Cornwall Strategy." (Mark O'Brien, via Twitter, 12/Aug/2021)

The UK Clean Air Strategy says:

"By implementing the policies in this strategy, we will reduce PM2.5 concentrations across the UK, so that the number of people living in locations above the WHO guideline level of 10 μg/m3 is reduced by 50% by 2025."

Anyone fancy installing one of these PM2.5 monitors where you live?
