| Zusammenfassung |
| Shipping sector is a large and growing source of emissions. Large quantities of nitrogen
oxides (NOX) and sulphur dioxide (SO2) are emitted from ships affecting the chemical
composition of the atmosphere in coastal areas. Changes of the world fleet over the
past decades suggest a continuously increasing trend of the shipping emissions.
Therefore, shipping emissions may partly offset the benefits from the reduction of
anthropogenic emissions over land. The objective of this study is to assess the impact of
shipping emissions on air quality degradation over Europe for a winter (January 2006)
and a summer month (July 2006) using CMAQ modeling system and the TNO
anthropogenic emission inventory for 2006. Results suggest that shipping emissions
increase NO2 and SO2 mixing ratios more than 90% over the sea and close to the
coastline, locally. Ship induced ozone contribution to total surface ozone exceeds 5%
over the sea and near the coastline during the summer month. The largest impact
is simulated over the Mediterranean Sea. Ship traffic emissions are estimated to
increase PM2.5 concentration during winter up to 40% over the Mediterranean
Sea while during summer an increase more than 50% is simulated over the sea. |
