摘要

The origin of deposited air borne contaminants can be difficult to determine. In this case Study, forensic techniques have been applied within the context of environmental Monitoring to attribute the source of airborne particles recovered from precipitation samples collected in the United Kingdom to the eruption of Eyjafjallajokull, Iceland. This volcanic eruption was well publicised in the British media1 with much attention focussed on the inconvenient short term effects of flight cancellations, re-routing and safety fears associated with aircraft encountering ash clouds. In a world-wide context these events are not uncommon. Similar events have occurred within the last year with volcanic activity in Eritrea affecting Ethiopian airspace and also activity in Chile affecting the airspace over much of South America,2 each publicised locally.
