EEA: Many Europeans still exposed to harmful air pollutants

Almost a third of Europe's city dwellers are exposed to excessive
concentrations of airborne particulate matter (PM), one of the most
important pollutants in terms of harm to human health as it penetrates
sensitive parts of the respiratory system. The EU has made progress over
the past decades to reduce the air pollutants which cause
acidification, but a new report published today by the European
Environment Agency (EEA) shows that many parts of Europe have persistent
problems with outdoor concentrations of PM and ground level ozone.
Environment Commissioner Janez Potočnik
said: "This report is a timely reminder of how important air quality is
to the health of our citizens. This is why I want 2013 to be the Year of
Air and why I will focus on strengthening our air quality laws to
tackle the problems identified today."
Professor Jacqueline McGlade, EEA Executive Director,
said: "European Union policy has reduced emissions of many pollutants
over the last decade, but we can go further. In many countries, air
pollutant concentrations are still above the legal and recommended
limits that are set to protect the health of European citizens. In fact,
air pollution reduces human life expectancy by around two years in the
most polluted cities and regions."
The EEA's 'Air quality in Europe — 2012 report'
examines citizens' exposure to air pollutants and provides a snapshot
of air quality in Europe. The report is intended to support the
development of more effective clean air policies.
Key findings
• Particulate matter (PM) is the most serious
air pollution health risk in the EU, leading to premature mortality.
The report estimates that in 2010, 21 % of the urban population in 2010
was exposed to PM10 concentration levels higher than the most
stringent, daily, EU limit value designed to safeguard health. Up to
30 % of the urban population was exposed to finer PM2.5 concentration
levels above the (less stringent) yearly EU limit values. According to
the WHO reference levels, which are even tighter than those imposed by
EU law, respectively up to 81 % and 95 % of urban dwellers were exposed
to PM concentrations that exceed the reference values set for the
protection of human health – underlining the urgency of the coming
review of air legislation.
• Ozone (O3) can cause respiratory
health problems and lead to premature mortality. Exposure in cities is
very high – 97 % of EU urban inhabitants were exposed to O3 concentrations above the WHO reference level in 2010. 17 % were exposed to concentrations above the EU target value for O3. In 2009, 22 % of arable land in Europe was exposed to damaging concentrations of O3, leading to agricultural losses.
• Nitrogen dioxide (NO2) is a
major cause of eutrophication (excessive plant and algal growth in
water) and acidification, and also contributes to the formation of PM
and O3. In 2010, 7 % of Europeans living in cities were exposed to NO2
levels above the EU limit values. National emissions of nitrogen oxides
in many European countries still exceed emission ceilings set by EU
legislation and under United Nations agreements.
• Benzo(a)pyrene (BaP) is a carcinogen. A
considerable proportion of the urban population in the EU (20-29 %
between 2008 and 2010) were exposed to concentrations exceeding the EU
target value, which must be met by 2013. The increase in BaP emissions
in Europe in recent years is therefore a matter of concern.
• Sulphur dioxide (SO2) is a big
success story: emissions have been reduced significantly in recent years
thanks to EU legislation requiring the use of emissions scrubbing
technology and lower sulphur content in fuels. 2010 was the first year
that the EU urban population was not exposed to SO2 concentrations above the EU limit value.
• Carbon monoxide, benzene and heavy metals
(arsenic, cadmium, nickel, lead) concentrations in outdoor air are
generally low, localised and sporadic in the EU, with few exceedances of
the limit and target values set by EU legislation.
Next Steps
In recent years, the EEA has published annual information on air pollutant emissions and exceedances of emission ceilings under the National Emission Ceilings (NEC) Directive.
Later this year, the EEA will publish a retrospective analysis of
whether the health and environmental objectives of the NEC Directive for
2010 have been met.
The European Commission is preparing a review of EU
air legislation in consultation with stakeholders and will put a
particular emphasis on air pollution policies in 2013.
Background
Poor air quality can cause heart disease, respiratory
problems, lung cancer, breathing difficulties and other illnesses. Some
pollutants can lead to eutrophication, reduced agricultural crop
yields, decreased forest growth and have an impact on the climate.
Emissions of several pollutants have fallen in recent years, resulting
in improved air quality in some areas. However, they have not always
resulted in a corresponding drop of atmospheric pollutant
concentrations. The persistent air quality problems require further
efforts in mitigating the emissions of several pollutants.
