A green group, Clear The Air, is warning that poor indoor air quality is putting the health of Hong Kong children at risk. A spokesman for the group, George Woo, said people spend 90 percent of their time indoors, where studies had shown pollutant levels could be up to five times higher than outside. Mr Woo said that local schools lacked the knowledge to improve indoor air quality.
