The conclusions we can draw from this study must be strictly limited to the acute response of children to moderate levels of airborne volcanic ash. Thus, we found no within-day effect, and no overall cumulative effect. There was a significant, but very small decrease in FVC and FEV1 over the first 24 hours, but we believe this is attributable to a diurnal effect rather than to ash.
