Air pollution affects over 90% of world's population
'Air pollution continues to rise at an alarming rate, and affects
economies and people's quality of life - it is a public health
emergency'
More than nine out of every 10 people on the planet live in areas
where air pollution breaches official safety limits - and millions of
people are dying as a result, according to new research by the World
Health Organisation (WHO).
An interactive map produced by WHO shows that vast areas of the world
are bathed in tiny particles from pollutants such as sulphate, nitrates
and black carbon, which can penetrate deep into the lungs and beyond,
leading to an array of deadly diseases. China, India, eastern Europe,
the Middle East and Africa are among the worst affected regions.
Heart attack, stroke and lung cancer can be caused by the particles,
known as PM2.5 and PM10, which also increase the risk of acute
respiratory infections.
While some of the dust is natural in places such as the Sahara, much
comes from the burning of fossil fuels, also the cause of global
warming. Almost all of England is above the WHO safety limit with places
where the air is considered safe to breathe largely confined to the
rural north-west and parts of Cornwall and Devon.
By contrast, the vast majority of Scotland's air is below the limits,
except for the central belt, particularly Glasgow. Northern Ireland is
also largely clear, apart from Belfast and a strip down the east coast.
Air pollution - indoor and outdoor - was linked to the deaths of some
6.5 million people worldwide in 2012, representing more than 11 per cent
of all deaths and making it one of the greatest threats to human health.
Of them, three million were 'solely attributable' to the quality of
outdoor air. The WHO said an estimated 16,355 British people died in
that year as a direct result of outdoor air pollution.
Dr Flavia Bustreo, assistant director general, WHO, said: "For people
to be healthy, they must breathe clean air from their first breath to
their last." The report, Ambient air pollution: A global assessment of
exposure and burden of disease, admitted there were 'significant
uncertainties' in the data about air pollution but said, the report
represented 'the best evidence available to date'.
Writing in the report, Dr Maria Neira, director of public health,
WHO, said: "Air pollution has become a growing concern in the past few
years, with an increasing number of acute air pollution episodes in many
cities worldwide.
"To date, air pollution, both, ambient (outdoor) and household
(indoor), is the biggest environmental risk to health, carrying
responsibility for about one in every nine deaths annually.
"Ambient air pollution alone kills around 3 million people each year,
mainly from non-communicable diseases. Only one person in 10 lives in a
city that complies with the WHO air quality guidelines.
"Air pollution continues to rise at an alarming rate, and affects
economies and people's quality of life; it is a public health
emergency." British Lung Foundation chief executive Dr Penny Woods said:
"These figures show a depressing picture of deaths due to air pollution
exposure, impacting on general respiratory health.
"The fact that so many deaths a year are recorded in the EU shows we
need urgent action to improve pollution levels. "That is why the British
Lung Foundation believes, we must all play a part in reducing harmful
pollution, working with other organisations to improve air quality. We
can do this by ensuring parliament brings in a new Clean Air Act, and
creating carefully designed clean air zones in air pollution hot spots
across the UK."
James Thornton, chief executive of ClientEarth, a group of lawyers
which campaigns on legal issues, said: "While air pollution is mostly
invisible, these figures show that many of us living in Britain are
breathing in unhealthy levels of it.
"In the UK and several other European countries we are using the
courts to force governments to uphold our right to clean air. Air
pollution is causing a public health crisis in many countries across the
world. This can only be overcome with swift, strong actions from
governments and industry alike."
