OVER 90% OF WORLD BREATHING BAD AIR: WHO

Nine out of 10 people globally are breathing poor quality air, the World Health Organisation said on Tuesday, calling for dramatic action against pollution that is blamed for more than six million deaths a year. The problem is most acute in cities, but air in rural areas is worse than many think, WHO experts said.

GENEVA: Nine out of 10 people globally are breathing poor quality air, the World Health Organisation said on Monday, calling for dramatic action against pollution that is blamed for more than six million deaths a year.

New data in a report from the UN’s global health body “is enough to make all of us extremely concerned,” Maria Neira, the head of the WHO’s department of public health and environment, told reporters.

The problem is most acute in cities, but air in rural areas is worse than many think, WHO experts said.

Poorer countries have much dirtier air than the developed world, according to the report, but pollution “affects practically all countries in the world and all parts of society”, Neira said in a statement. “It is a public health emergency,” she said.

“Fast action to tackle air pollution can’t come soon enough,” she added, urging governments to cut the number of vehicles on the road, improve waste management and promote clean cooking fuel. Southeast Asia and the Western Pacific region -- including China -- are the hardest hit, the data showed.

South Asia is also badly affected, with the WHO saying poor air quality is responsible for the deaths of more than 600,000 people in India and 37,000 people in Bangladesh every year.

Pakistan too is suffering, with experts blaming unplanned and unsustainable development and warning that proposals for more coal-fired power stations will further worsenair quality.

Tuesday’s report was based on data collected from more than 3,000 sites across the globe.

It found that “92 per cent of the world’s population lives in places where air quality levels exceed WHO limits”.

The data focuses on dangerous particulate matter with a diameter of less than 2.5 micrometres, or PM2.5, which includes toxins like sulfate and black carbon, which can penetrate deep into the lungs or cardiovascular system.

Air with more than 10 microgrammes per cubic metre of PM2.5 on an annual average basis is considered substandard. In some regions satellite data has been complemented by groundlevel PM2.5 measurements, but in much of the developing world ground readings remain unavailable, forcing the WHO to rely on cruder estimates.
