New rules planned for synthetic tracks
Print Edition
SHANGHAI’S quality watchdog is working with industry associations to come up with a set of standards for artificial running tracks after the recent health scare in several schools in Shanghai and neighboring Jiangsu Province.
The current standards for synthetic running track only cater to dangerous substances in materials, such as benzene, toluene and xylene, free toluene diisocyanate, as well as dissoluble lead, cadmium, chrome and mercury, Shen Weimin, deputy director of Shanghai Quality and Technical Supervision Bureau, said yesterday.
The rules were introduced in May 2012.
Shen said that there could be risks posed by other substances that are not included in the standards, like glues or other additives that are used while paving the tracks.
He said it was possible that some of them could produce harmful substances.
Shen said that the quality watchdog was now investigating the hidden dangers of additives used in the construction of tracks.
It would then introduce new standards on using such materials but only after consultation with the local association of chemical construction material industry.
Since the new semester began in September, two kindergartens in Shanghai’s Songjiang and Minhang districts and four schools in Jiangsu reported that the newly laid artificial tracks had led to nosebleed, skin rashes and other symptoms in some students.
Experts have pointed out that some constructors might have added unqualified supporting materials while laying the tracks, which can cause allergic reactions among children.
Samples of the tracks from the two kindergartens have been sent to a lab in East China University of Science and Technology for tests. The results are still awaited.
