Confocal microscopy 3D imaging and bioreactivity of La Palma volcanic ash particles.

In September 2021 an eruption began of Cumbre Vieja, La Palma (Spain) that lasted 3 months. Previous studies have shown that volcanic ash particles can be associated with adverse effects on human health however, the reasons for this are unclear.
