The present study describes the measurement, chemical characterization and delineation of sources of fine particulate matter (PM 2.5 , V and BC) and Sea Sprays (Cl -and Na). Backward-in-time trajectories showed a significant contribution by long distance transport of fine aerosols to the overall daily PM 2.5 levels. Results are consistent with previous studies and highlight the need for more comprehensive research into particulate air pollution in Rabigh and the neighboring areas. This is essential for the formulation of sustainable guidelines on air pollutant emissions in Saudi Arabia and the whole Middle East.
