Origin and SEM analysis of aerosols in the high mountain of Tenerife (Canary Islands)

A significant increase in African dust events reaching the Canary Islands, including Teide National Park, was identified, with 79% of air masses originating from Africa. This study highlights the complex mixture of respirable particles, such as quartz microcrystals and freshwater diatom tests, which pose potential respiratory health risks, particularly in high-altitude regions like Tenerife's highlands. Researchers used backward trajectory analysis and scanning electron microscopy (SEM) to characterize aerosol composition during dust intrusions from March 2004, revealing dominant mineral and biological components with implications for airway pathology.
