Ambient air pollution and emergency department visits and hospitalisation for cardiac arrest: a population-based case–crossover study in Reykjavik, Iceland
Objectives To assess the association between traffic-related ambient air pollution and emergency hospital visits for cardiac arrest.Design Case–crossover design was used with a lag time to 4 days.Setting The Reykjavik capital area and the study population was the inhabitants 18 years and older ident...

The pollutants were nitrogen dioxide (NO2), particulate matter with aerodynamic diameter less than 10 µm (PM10), particulate matter with aerodynamic diameter less than 2.5 µm (PM2.5) and sulfur dioxide (SO2) with adjustment for hydrogen sulfide (H2S), temperature and relative humidity.Main outcome measure OR and 95% CIs per 10 µg/m3 increase in concentration of pollutants.Results The 24-hour mean NO2 was 20.7 µg/m3, mean PM10 was 20.5 µg/m3, mean PM2.5 was 12.5 µg/m3 and mean SO2 was 2.5 µg/m3. PM10 level was positively associated with the number of emergency hospital visits (n=453) for cardiac arrest.
