Story below from The Lancet.
There is now no doubt that air pollution, and
especially fine particulate matter (PM2·5), has many serious
consequences for health and leads to avoidable premature deaths. A large
body of evidence exists for short-term and long-term effects on
cardiovascular diseases and respiratory diseases—including chronic
obstructive pulmonary disease, asthma, and lung cancer. Newly emerging
evidence suggests possible effects on premature births, lung-function
development in children, and accelerated progression of atherosclerosis
and cognitive impairment. Even more worrying is that these effects may
exist at low levels of air pollution and that there is no safe threshold
level, rather a linear concentration-response relationship.
The current EU limit for PM2·5 at 25 μg/m3 annual average is already higher than the WHO Air Quality Guidelines (10 μg/m3),
a discrepancy that needs urgent attention but this might not be enough.
As the EU has declared 2013 “The Year of the Air”, there is hope that
air pollution—the most important environmental risk factor for the
health of Europeans—will get the attention it deserves.
However, discussions need to go beyond health. A new report, The unpaid health bill: how coal power plants make us sick,
released by the Health and Environment Alliance on March 7, points out
the underappreciated source of air pollution from coal power plants. It
estimates that 18 200 premature deaths per year and up to €42·8 billion
in health-related costs are attributable to coal power generation. The
number of coal power plants has been decreasing for decades but they are
now increasing again with 500 new plants under discussion. They emit
PM, but also toxic heavy metals, such as mercury. Germany, Poland, and
Romania's coal power plants are responsible for half of all estimated
health impacts, and of course health effects do not respect borders. The
report calls for phasing out of coal power in Europe by 2040 and for an
immediate moratorium on the construction of new plants.
Tackling
air pollution is an important example where Europe-wide joined-up
thinking is urgently needed. Energy, climate change, and health—some of
the most important issues of the 21st century—must be considered
together in all relevant policies.
