Action call on smog, mental health link

Experts urged to collaborate on issue amid worsening air pollution

Severe pollution has been linked to respiratory problems such as asthma and bronchitis, but few people realize it could trigger "smog depression", said Tian Chenghua, a professor at the Institute for Psychiatric Research at Peking University's No 6 Hospital.
