Zusammenfassung |
The chemical composition of the plumes of seagoing ships was measured during
a two week long measurement campaign in the port of Rotterdam, Hoek van
Holland The Netherlands, in September 2009. Altogether, 497 ships were
monitored and a statistical evaluation of emission factors (g kg−1
fuel) was provided. The concerned main atmospheric components were SO2,
NO2, NOx and the aerosol particle number. In addition, the
elemental and water-soluble ionic composition of the emitted particulate
matter was determined. Emission factors were expressed as a function of ship
type, power and crankshaft rotational speed. The average SO2 emission
factor was found to be roughly half of what is allowed in sulphur emission
control areas (16 vs. 30 g kg−1 fuel), and exceedances of this limit were
rarely registered. A significant linear relationship was observed between
the SO2 and particle number emission factors. The intercept of the
regression line, 4.8 × 1015 (kg fuel)−1, gives the
average number of particles formed during the burning of 1 kg zero sulphur
content fuel, while the slope, 2 × 1018, provides the average
number of particles formed with 1 kg sulphur burnt with the fuel.
Water-soluble ionic composition analysis of the aerosol samples from the
plumes showed that ~144 g of particulate sulphate was emitted
from 1 kg sulphur burnt with the fuel. The mass median diameter of sulphate
particles estimated from the measurements was ~42 nm. |
