Effects of long-term exposure to PM10 and NO2 on asthma and wheeze in a prospective birth cohort.
Epidemiological studies on the effect of urban air pollution on childhood asthma have shown conflicting results and so far no consistent association has emerged. However, a common limitation in previous studies has been exposure misclassification leading to uncertainties in risk estimates.The aim of this study was to analyse the effects of long-term exposure to particulate matter (PM10) and nitrogen dioxide (NO2) on the prevalence of asthma and wheeze within a population-based birth cohort--the Manchester Asthma and Allergy Study (MAAS). ⋯ No evidence of a significant association between long-term exposure to PM10 and NO2 and the prevalence of either asthma or wheeze was found.

Evaluating the impact of air pollution on the incidence of out-of-hospital cardiac arrest in the Perth Metropolitan Region: 2000-2010.
Out-of-hospital cardiac arrest (OHCA) remains a major public health issue. Several studies have found that an increased level of ambient particulate matter (PM) smaller than 2.5 microns (PM2.5) is associated with an increased risk of OHCA. We investigated the relationship between air pollution levels and the incidence of OHCA in Perth, Western Australia. ⋯ Elevated ambient PM2.5 and CO are associated with an increased risk of OHCA.

ReviewA systematic review of air pollution and incidence of out-of-hospital cardiac arrest.
Studies have linked air pollution with the incidence of acute coronary artery events and cardiovascular mortality but the association with out-of-hospital cardiac arrest (OHCA) is less clear. ⋯ Larger studies have suggested an increased risk of OHCA with air pollution exposure from PM(2.5) and ozone.
