   The quality of the school mixed plastic runway is about the healthy growth of every child. It is necessary to determine whether the plastic runway is environmentally friendly, and whether it contains harmful substances to children. The current plastic runway national standard has not been able to keep up with the rhythm of adding chaos.

  
  The "indoor air quality standard" is an authoritative standard for measuring indoor air quality, which is stricter than the national standard of plastic runway. More scientific use of indoor air quality testing method to control the environmental safety of runway surface products. Each of its environmental indicators is greatly lower than the requirements of air quality standards, to achieve the highest level of environmental protection performance in China.
  
  The TVOC of the school mixed plastic runway is less than 0.4mg/m3 per cubic meter of air. It is 0.6mg/m3 and 0.2mg/m3 less than the standard of "indoor air quality standard". This is the absolute confidence of the plastic runway of Yun Jia's school for the environmental quality.
  
  In other words, the methanol HCHO content of the school breathable plastic runway accounts for only 3% of the indoor air index. Benzene and benzene are "undetected" and have no comparability with indoor air indicators. The results of benzene, benzene, benzene and benzo (a) pyrene in the school breathable plastic runway, including benzene, toluene, xylene and benzo (a) pyrene, are "undetected", not only lower than the indoor decoration standards, compared with the standard for benzene and benzene in the room air quality standard. The sum of 1.51mg/m3 is lower, and the environmental index is higher.
