Over two million deaths occur each year as a direct result of human-caused outdoor air pollution, a new study has found.
In addition, while it has been suggested that a changing climate can exacerbate the effects of air pollution and increase death rates, the study shows that this has a minimal effect and only accounts for a small proportion of current deaths related to air pollution.
The study, which has been published today, 12 July, in IOP Publishing’s journal Environmental Research Letters, estimates that around 470,000 people die each year because of human-caused increases in ozone.
It also estimates that around 2.1 million deaths are caused each year by human-caused increases in fine particulate matter (PM2.5) – tiny particles suspended in the air that can penetrate deep into the lungs, causing cancer and other respiratory disease.
