Background: Respirable crystalline silica (RCS) continues to pose a risk to human health worldwide. Its variable toxicity depends on inherent characteristics and external factors which influence surface chemistry. Significant population exposure to R...

The surface reactivity and implied toxicity of ash produced from sugarcane burning (2012)
Journal Article
Le Blond, J., Tomatis, M., Horwell, C., Dunster, C., Murphy, F., Corazzari, I., …Fubini, B. (2012). The surface reactivity and implied toxicity of ash produced from sugarcane burning. Environmental Toxicology, 29(5), 503-516. https://doi.org/10.1002/tox.21776

Sugarcane combustion generates fine-grained particulate that has the potential to be a respiratory health hazard because of its grain size and composition. In particular, conversion of amorphous silica to crystalline forms during burning may provide... Read More about The surface reactivity and implied toxicity of ash produced from sugarcane burning.

Sakurajima volcano: a physico-chemical study of the health consequences of long-term exposure to volcanic ash (2012)
Journal Article
Hillman, S., Horwell, C., Densmore, A., Damby, D., Fubini, B., Ishimine, Y., & Tomatis, M. (2012). Sakurajima volcano: a physico-chemical study of the health consequences of long-term exposure to volcanic ash. Bulletin of Volcanology, 74(4), 913-930. https://doi.org/10.1007/s00445-012-0575-3

Regular eruptions from Sakurajima volcano, Japan, repeatedly cover local urban areas with volcanic ash. The frequency of exposure of local populations to the ash led to substantial concerns about possible respiratory health hazards, resulting in many...
