People living in polluted areas are more likely to die by suicide or be depressed, research shows.
Scientists reviewed studies from 16 countries looking into the long-term impact of breathing in toxic airborne particles on mental health.
They found that as the level of pollution increased, so too did the rate of number of suicides and depression diagnoses.
It is thought the toxic particles emitted by cars and industry cause inflammation in the brain when they seep into the bloodstream after being inhaled, or affect levels of stress hormones – both of which have been linked to poor mental health.
Analysis showed average exposure to PM2.5 – the finest type of particulate matter – was 44 micrograms per metre cubed (ug/m3).
For every 10ug/m3 above this amount, there was around a 10 per cent increase in cases of depression and a two per cent rise in suicides.
