SECOND-HAND smoke in Shanghai Internet cafes is seven times more dangerous than in outdoor public spaces, putting users at risk of pneumonia and asthma, Fudan University researchers said today.
And restaurant workers were 7.5 times more likely to develop respiratory diseases than kindergarten staff, according to their research from the School of Public Health.
They measured tiny particulate matter, smaller than 2.5 micrometers, in Internet cafes and found the air seven times denser than that in the outdoors.
Researchers studied 3,500 people from seven industries in a Smoke-Free Shanghai Campaign before smoking bans come into force on March 1.
They found the air quality in leisure parlors and catering industries the worst and many workers reported asthmatic coughs, eye pain, and respiratory irritations.
