| Abstract | ||||
| Understanding the seasonal variations of polycyclic aromatic hydrocarbons (PAHs) concentrations in ambient air in urban/rural or industrial regions is important to the effective control of air pollution in these regions. Based on an approximately a year round dataset (from January to November 2014), a total of 48 atmospheric samples were collected by high volume active air sampler over one year seasonal monitoring in order to assess the variation of PAHs concentrations in different areas through different seasons in south Al Tabbin area. The gaseous and particulate phases of PAHs were extracted and analyzed using GC/MS together. The total air concentrations of 16 USEPA PAHs in the study area ranged from 76.48 ± 19.44 µg/m3 to 26995.86 ± 2835.91 µg/m3, with an average concentration of 7085.08 ± 773.98 µg/m3. Seasonal trends of PAH concentrations were observed with high concentration in winter and low in summer where the average concentration of PAHs in winter were ~1.6 times higher than that in summer. This mainly attributed to meteorological conditions. | ||||
