Washington [US]: Exposure to ozone gas air pollution is linked to symptoms of depression in adolescents, according to a recent study.
The study, published in the journal 'Developmental Psychology', is the first to link ozone levels to the development of depression in adolescents over time.
Ozone is a gas that is produced when various pollutants from motor vehicle exhaust, power plants and other sources react to sunlight. Higher ozone levels have been linked to various physical ailments, including asthma, respiratory viruses and premature death from respiratory causes.
