Iron-induced hydroxyl radical generation from the surface of volcanic ash particles is a possible mechanism of respiratory toxicity in addition to crystalline-silica induced pathogenicity. Here we show that volcanic ash generates hydroxyl radicals, w... Read More about Iron-induced hydroxyl radical generation from basaltic volcanic ash.

Volcanic ash has the potential to cause acute and chronic respiratory diseases if the particles are sufficiently fine to enter the respiratory system. Characterization of the grain-size distribution (GSD) of volcanic ash is, therefore, a critical fir...
