We adopted a protocol for the rapid analysis of volcanic ash particles, for the purpose of informing respiratory health risk assessments. In a farm site in the middle of the district was moved due to repeated jökulhlaup. Sigurmundsson, F. The climate change and accompanied hazards during the 19th century changed the landscape of the Suðursveit district significantly. Seventy five years later, in , the largest estate was completely destroyed by a jökulhlaup.

Thus it was clear that our approach to increase beam current could not be simply trying to run at a higher temperature and the preferred way was to operate with a cathode that has a lower work function.

The dispenser cathode initially used was the type M made by SpectraMat.

The result was similar even after we had revised the activation and handling procedures to adhere more closely to the recommend steps taking longer time and nonstop to do the out-gassing. Vacuum was a major concern in considering the cathode's performance.

Although the vacuum gauges at the injector vessel indicated 10 -8 Torr, the actual vacuum condition near the cathode in the central region of the vessel, where there might be significant out-gassing from the heater region, was never determined. Poor vacuum at the surface of the cathode degraded the emission by raising the work function value. Seventy five years later, inthe largest estate was completely destroyed by a jökulhlaup.

We adopted a protocol for the rapid analysis of volcanic ash particles, for the purpose of informing respiratory health risk assessments. Ash collected from deposits underwent a multi-laboratory physicochemical and toxicological investigation of their mineralogical parameters associated with bio-reactivity, and selected in vitro toxicology assays related to pulmonary inflammatory responses. Ash from the eruption of Grímsvötn, Iceland, in was also studied.
