Sažetak
A statistical Lagrangian atmospheric transport model was used to generate annual maps of deposition of sulphur and
nitrogen for the United Kingdom at a 5 x 5 km2 resolution for the year 2005 and to assess the contribution attributed to emissions of
SO2 and NOx from international shipping. A future emissions scenario for the year 2020 was used to investigate changes in the
relative contribution of shipping emissions. The results show that, if shipping emissions are assumed to increase at a rate of 2.5%
per year, their relative contribution to total sulphur and oxidised nitrogen deposition are expected to increase from 15% and 12%
respectively to 37% and 28% between 2005 and 2020. Enforcement of the International Maritime Organisation (IMO) agreement to
reduce the sulphur content in marine fuel to 0.5% was estimated to result in a 30% reduction in total sulphur deposition to the UK
for the year 2020 compared to a business as usual scenario, with the result that the relative contribution from shipping to sulphur
deposition in the UK would be reduced to 9% of the total
