Chemical speciation of fine airborne particles in Abu Dhabi. NILU OR

Hak, C.; Lopez-Aparicio, S.

PM2.5 was sampled at two urban background sites in Abu Dhabi (Khalifa in the city of Abu Dhabi and Bida Zayed) and analysed chemically for further source identification and quantification. Understanding of source contributions to PM2.5 is a prerequisite for the formulation of effective control strategies for PM2.5 emissions.
For both sites, five source factors were identified. Long-range transported aerosol is the largest contributor (~41%) to average PM2.5 mass concentrations at both sites. It gradually forms from SO2, which is possibly emitted into ambient in the Arabian Gulf area, while it is transported to the sites. Mineral dust was found to be the second most important source, contributing ~25% at both sites. It represents an ubiquitous natural contribution of mainly regional origin to particulate matter in Abu Dhabi.
Other source contributions to particle concentrations found at Khalifa identified were: local traffic (15.1%), shipping/industry (10.5%) and sea salt (4.0%). The latter is a natural contribution.
At Bida Zayed, a mixed traffic/industry factor (13.2%) was found, as well as another two factors of natural origin, explaining 11.4% and 8.7%

Esso Slagen refinery - Monitoring program 2006-2011. NILU OR

Berglen, T.F.; Tønnesen, D.; Andresen, E.; Arnesen, K.; Li, L.; Ofstad, T.; Rode, A.; Schmidbauer, N.

NILU - Norwegian Institute for Air Research has been conducting a monitoring pogram for Esso (ExxonMobile) at Slagen refinery from 2006-2011. The program included monitoring of meteorology, SO2, PM10, BTEX and rain water chemistry. Results show that air quality standards for SO2 were exceeded in 2009, both concerning hourly mean values (29 values above 350 µg/m3), daily mean values (five values above 125 µg/m3) and annual mean (20,3 µg/m3 vs 20 µg/m3). For the other components there were no exceedence of air quality standards, except for benzene in 2009 (2,6 µg/m3 vs national target value of 2 µg/m3).

Testing of emission factors for woodburning emissions in AirQUIS. A sensitivity study for PM2.5 in Oslo. NILU OR

Sundvor, I.; Randall, S.

Emissions from domestic heating due to woodburning are one of the main emissions sources of PM in Norway. However there are uncertianties in the emission data and especially how much these emissions contribute to the concentrations. Dispersion modeling has been performed for Oslo with different emission scenarios to test some of the parameters related to this emission source. The model results show that the wood burning contribution is overestimated, especially in the evening and conclusions are that the emissions of wood burning are wrong both in quantity as well as spacial distribution in time variation.
