KEY POINTS about Air quality data base


Unhealthy Air:

More than 6,000 cities in 117 countries are now monitoring air
quality but their residents are still breathing unhealthy levels of fine particulate
matter and nitrogen dioxide, while people in low and middle-income countries
suffer the highest exposure.

Increased Collection of Data:

As many as 2,000 more cities and human
settlements are now recording ground monitoring data for particulate matter,
PM10 and/or PM2.5, than in the last update (2018).
Compliance with WHO Air Quality Guidelines: In the 117 countries
monitoring air quality, the air in 17% of cities in high-income countries falls
below WHO’s air quality guidelines for PM 2.5.

World Health Day 2022

World Health Day, marked on 7 April, will focus global attention on urgent actions
needed to keep humans and the planet healthy and foster a movement to create
societies focused on well-being.

IMPROVEMENT NEEDED IN THIS REGARDS

Europe and, to some extent, North America, remain the regions with the most
comprehensive data on air quality. In many low- and middle-income countries, while
PM2.5 measurements are still not available, they have seen large improvements for
measurements between the “air quality data anaylsis” last database update in 2018 and this one, with an
additional 1500 human settlements in these countries monitoring air quality.

FACTS AND FIGURES

In the 117 countries monitoring air quality, the air in 17% of cities in high-income
countries fall below WHO Guidelines for PM2.5 or PM 10. In low- and middle-income
countries, “air quality data analysis” in less than 1% of the cities complies with WHO recommended
thresholds

Globally, low- and middle-income countries still experience greater exposure to
unhealthy levels of PM compared to the global average, but NO2 patterns are different,
showing less difference between the high- and low- and middle-income countries

About 4000 cities/human settlements in 74 countries collect NO2 data at ground level.
Aggregated, their measurements show that only 23% of people in these places breathe
annual average concentrations of NO2 that meet levels in the recently updated version
of WHO GUIDELINES.

“Current energy concerns highlight the importance of speeding up the transition
to cleaner, healthier energy systems,” said Dr Tedros Adhanom Ghebreyesus,
WHO Director-General. “Air quality data analysis”
He added, “High fossil fuel prices, energy security, and the urgency of
addressing the twin health challenges of air pollution and climate change,
underscore the pressing need to move faster towards a world that is much less
dependent on fossil fuels.”

EXPERT’S VEIWS

Steps governments can take to improve “air quality data analysis” and health

A number of governments are taking steps to improve air quality, but WHO is
calling for a rapid intensification of actions to:
Adopt or revise and implement national air quality standards according to
the latest “WHO Air Quality data analysis” Guidelines
Monitor air quality and identify sources of air pollution
Support the transition to exclusive use of clean household energy for
cooking, heating and lighting
Build safe and affordable public transport systems and pedestrian- and
cycle-friendly networks
Implement stricter vehicle emissions and efficiency standards; and enforce
mandatory inspection and maintenance for vehicle
Invest in energy-efficient housing and power generation
Improve industry and municipal waste management

Reduce” agricultural waste incineration”, forest fires and certain forestry
activities.
Include air pollution in curricula for health professionals and providing tools
for the health sector to engage.
