Size segregated ionic species collected in a harbour area.

Water-soluble ions were analysed in size segregated aerosol samples collected in the port of Alicante (Southeastern Spain) during summer and winter using a multistage cascade impactor. Seasonal variations in the size distributions of the analysed components and the influence of bulk materials handling (loading/unloading and stockpiling) at the docks were investigated. The size distributions of SO, NH and K were characterized by prominent peaks in the condensation and droplet modes, both in summer and winter, while those of Ca, Na, Mg and Cl had a main peak centred at ∼4 μm.

Insights into the origin and evolution of carbonaceous aerosols in a mediterranean urban environment.

Organic carbon (OC) and elemental carbon (EC) concentrations were measured in PM and PM daily samples collected at an urban station in Elche (southeastern Spain) from February 2015 to February 2018. The effect of seasonal weather conditions, traffic, and specific pollution events (Saharan dust outbreaks and local pollution episodes) on the variability of carbonaceous aerosol levels was studied in this work. The joint contribution of carbonaceous species to PM and PM mass concentrations was, respectively, 48% and 26%.
