People exposed to higher levels of air pollution are more likely to suffer depression or take their own life, London researchers have found.  They raised concerns about the tiny PM10 and PM2.5 particulates that are emitted from the brakes and tyres of all types of vehicles — including “greener” electric buses and cars.

Experts worry that although central London’s ultra low emission zone is reducing nitrogen oxide exhaust gases, it is not cutting particulates because drivers are switching from petrol or diesel to hybrid cars to avoid paying the £12.50 daily levy.

Today’s study, led by University College London, is the first to use a “meta analysis” of five previously published studies to draw conclusions about the link between air pollution and mental health.
