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

Hak, C.; Lopez-Aparicio, S.; Sivertsen, B.

Chemical speciation results of PM2.5 filter samples from eight sites in Abu Dhabi are discussed. This is the third interim report, covering a total of 40 filter samples. As one aim of this sampling study was to use the speciation results for health impact studies, samples with high particle loads and high degree of blackness were selected for analysis, and compared to samples with typical particle loads. Particles with diameters less than 2.5 µm were analysed for elements, inorganic ions and carbonaceous fractions.
The most abundant elements were found to be crustal elements, contributing on average 14% to PM2.5 mass. Reconstructing the mass of crustal oxides, approximately 44% of the fine particle mass was estimated to be associated with mineral dust. The concentrations of most heavy metals were below limit values for annual averages at all sites. For nickel, it was found that the Guideline Value may be exceeded at one traffic site.
Inorganic ions (sulphate, nitrate, ammonium, sodium, chloride) explain on average 34% of the PM2.5 mass in Abu Dhabi. Remarkably high sulphate concentrations account for the major part (on average 26%). Particulate sulphate in Abu Dhabi is likely to have both natural (as a result of the local composition of mineral dust) and anthropogenic sources which cannot be separated with the applied analytical methods. An anthropogenic contribution of ~6% comes from the secondary inorganic ions nitrate and ammonium.
Total carbon, which consists of elemental carbon, organic carbon and carbonate carbon contributed on average 14% to PM2.5 mass. About 30% of total carbon was estimated to be carbonate of likely natural origin. Elemental carbon and most organic carbon are expected to be of anthropogenic origin.
PM in Abu Dhabi has a strong signature of natural sources (mineral dust). A detailed apportionment of sources requires further analyses.
