Second-hand smoke in the home more harmful than air pollution

24 Nov 2014Registered users

Pollution caused by fine particulate matter (PM2.5) is around ten times higher in homes where people smoke indoors compared with non-smoking homes, a study from Scotland has found. Furthermore, home air pollution from smoking appears to dwarf that from outdoor sources. Approximately 20% of those living in smoking homes in Scotland will inhale a lifetime mass of PM2.5 greater than the median value predicted for a non-smoker living in a heavily polluted urban setting.
