Work was suspended in 2008, owing to public protests over radiation fears  despite an environmental assessment by the Shanghai Academy of Environmental Sciences saying the line was safe and would not affect air and water quality, and noise pollution could be controlled.  According to China Daily, as reported on People's Daily Online 27 February 2009, the Shanghai municipal government was considering building the maglev line underground to allay the public's fear of electromagnetic pollution and the final decision on the maglev line had to be approved by the National Development and Reform commission.
