    Physicochemical Characterization and Seasonal Variations of PM10 Aerosols in a Harsh Environment حسب Hamdan, Nasser

    منشور في 2021
    "…Seasonal variation of the average total mass concentrations and the average mass concentration of elements emitted from natural sources show that the hot season is associated with higher pollution levels compared to the cold season due to increased dust events in the spring and summer. Correlation coefficients between elements have identified elements originating from common sources such as dust storms (e.g., Si, Ca, Al, Fe, Ti, Mn) and sea breeze (Cl and Na), in addition to anthropogenic elements. …"
