Chinese schools ordered to remove toxic running tracks
Schools across China have been ordered to remove running tracks made from toxic materials which have been blamed for illnesses among students.
The incident is the latest in a long line of product scandals which have been blamed on corruption and poor oversight.
The education ministry said nationwide inspections by environmental and consumer protection departments have been ordered over the summer school break.
Any track found to be unsafe must be removed, the statement said, while the construction of new tracks will be suspended until contractors can be properly vetted to ensure they meet industry standards.
Investigations will also be conducted into officials and others found to have been negligent or corrupt.
Those found guilty will be punished severely "with no mercy given," the statement said.
Tracks made from recycled tyres and other industrial waste are believed to have caused dizziness, nosebleeds and respiratory problems among students in Beijing and several outlying provinces.
One Beijing school has already begun tearing up its track after students fell ill during a stretch of particularly hot weather.
China has suffered recurrent consumer safety scandals over recent years, prompting public outrage and driving a market for imported baby formula, cosmetics and other products.
School safety has also been an issue, with badly designed buildings leading to crushing incidents.
State broadcaster CCTV also recently reported an outbreak of health problems among students at a high school campus in the eastern province of Zhejiang, possibly linked to polluted soil, although local authorities said inspections turned up no environmental problems.
