A research has found an increased hospital admissions for all causes, including mental illnesses, in relation to a long-term exposure to air pollution. The Scottish study, published in the British Medical Journal (BMJ) Open, found that a higher exposure to nitrogen dioxide (NO2) and particulate matter (PM10 and PM2.5) combined was linked to a higher hospitalisations for cardiovascular, respiratory and infectious diseases. Researchers from the University of St Andrews, UK, found that for every one micron per cubic metre increase in PM2.5 and NO2 pollutants, the incidence for hospitalisations for respiratory conditions rose by over four per cent and one per cent, respectively. Further, higher hospital admissions for mental or behavioural disorders were associated with an increased exposure to nitrogen dioxide.
