Emergency Hospital Visits in Association with Volcanic Ash, Dust Storms and Other Sources of Ambient Particles : A Time-Series Study in Reykjavik, Iceland
Volcanic ash contributed significantly to particulate matter (PM) in Iceland following the eruptions in Eyjafjallajökull 2010 and Grímsvötn 2011. This study aimed to investigate the association between different PM sources and emergency hospital visits for cardiorespiratory causes from 2007 to 2012....
