Depression and suicide linked to air pollution in new global study

Cutting toxic air might prevent millions of people getting depression, research suggests

People living with air pollution have higher rates of depression and suicide, a systematic review of global data has found.

Cutting air pollution around the world to the EU's legal limit could prevent millions of people becoming depressed, the research suggests. This assumes that exposure to toxic air is causing these cases of depression. Scientists believe this is likely but is difficult to prove beyond doubt.
