Abstract
Carbonaceous aerosol concentrations and sources were compared during a yearlong study at two sites in East and West Jerusalem that were separated by a distance of approximately 4 km. One in six day 24-h PM2.5 elemental and organic carbon concentrations were measured, along with monthly average concentrations of particle-phase organic compound tracers for primary and secondary organic aerosol sources. Tracer compounds were used in a chemical mass balance (CMB) model to determine primary and secondary source contributions to organic carbon. The East Jerusalem sampling site at Al Quds University experienced higher concentrations of organic carbon (OC) and elemental carbon (EC) compared to the West Jerusalem site at Hebrew University. The annual average concentrations of OC and EC at the East Jerusalem site were 5.20 and 2.19 μg m−3, respectively, and at the West Jerusalem site were 4.03 and 1.14 μg m−3, respectively. Concentrations and trends of secondary organic aerosol and vegetative detritus were similar at both sites, but large differences were observed in the concentrations of organic aerosol from fossil fuel combustion and biomass burning, which was the cause of the large differences in OC and EC concentrations observed at the two sites.
