UK HPA publishes a paper on on the possible effects on health of exposure to volcanic ash and associated gases

The paper was prepared in the intensive phase of Eyjafjallajökull volcano eruption. The paper concludes that exposure to such concentrations of ash as were likely to occur in the UK were not likely to have serious effects on health, neither in terms of short nor long term effects. It is unlikely that volcanic ash is as toxicologically active as combustion-generated particles and calculations of impacts based on epidemiological studies of the effects of the usual ambient aerosol are likely to be misleading.
