| Zusammenfassung |
| We present a modeling study of the long-range transport of pollution from
Europe, showing that European emissions regularly elevate surface ozone by
as much as 20 ppbv in summer in northern Africa and the Near East. European
emissions cause 50–150 additional violations per year (i.e. above those
that would occur without European pollution) of the European health standard
for ozone (8-h average >120 μg/m3 or ~60 ppbv) in
northern Africa and the Near East. We estimate that European ozone pollution
is responsible for 50 000 premature mortalities globally each year, of which
the majority occurs outside of Europe itself, including 37% (19 000) in
northern Africa and the Near East. Much of the pollution from Europe is
exported southward at low altitudes in summer to the Mediterranean Sea,
northern Africa and the Near East, regions with favorable photochemical
environments for ozone production. Our results suggest that assessments of
the human health benefits of reducing ozone precursor emissions in Europe
should include effects outside of Europe, and that comprehensive planning to
improve air quality in northern Africa and the Near East likely needs to
address European emissions. |
