This paper analyses two distributions of particulate matter, PM10 and PM2.5 , focusing on total mass and constituents, including elemental and ionic components. It assesses the proportion of these constituents to the total PM mass, with ensuring data reliability. The study also investigates the chemical complexity of species and interactions within PM, including physical processes and reactions forming secondary aerosols. The paper also examines the correlation between particle size and salt formation, exploring PM variability drivers and aerosol formation. The final section examines potential primary and secondary sources of emissions that contribute to the overall particulate matter using EPA PMF model.
