El segnalista el ga condoto alcune insenamento . Secondo l'ispesion del ristorante, el raporto che ła pista de ła pista de ła pista rilassarà prima dopo ła seconda ła segonda de ła Scoła de ła Scuola Ssion de ła Scoła de ła Scoła de ła Scoła de ła Scoła de ła Scoła de ła Scoła de ła scuoła de ła Scoła de ła scuoła de ła scuoła de ła scuoła de ła scuoła, de ła scuoła, un esperto de ła scuołasion de l'Aceo de l'Educasionałe de ła Scerasion de ła Scerasion de ła Scerasion de ła Scerasion de ła Scerasion de ła Scerasion de ła Scerasion de ła Scerasion de ła Scerasion de ła Scerasion de ła Scerasion de ła Scerasion de ła Secołasion de l'amato de ła Scerasion de ła Semacia de ła Sesta de ła Sesta de ła proposita. materials, mainly toluene diisocyanate, which is confirmed by relevant environmental monitoring agencies. The material produced in the hot or strong light will release toluene diisocyanate gas, which is very harmful to the human body. The expert called for "terminating the school to lay the plastic track as soon as possible".
After many twists and turns, the reporter finally heard that this statement was made by a sports full-time scientific researcher named Bai Wenfei of the Institute of Basic Education of the Beijing Academy of Educational Sciences. When the reporter dialed the phone, the other party said, "White teacher is not here, we are the research department, very busy, you reporters don't look for it here" hurriedly hang up the phone. In the following days, the reporter made the call continuously and got the same answer. The reporter turned around and went to the "Environmental Monitoring and Confirmation Agency" mentioned by the White Expert – China Indoor Decoration Association Indoor Environmental Monitoring Center. Song Guangsheng, director of the center, said in an interview with reporters that the situation disclosed by sports experts is true. The chief culprit in the release of poison gas from plastic track is indeed the toluene diisocyanate substance referred to as TDI in English. According to Song Guangsheng, TDI is a colorless transparent or light yellow liquid used as a curing agent for the manufacture of polyurethane paints and adhesives and połiuretane rivestimenti . In vision del fato che TDI no ła vien doparada soło inte łe piste de plàstega, ma anca in sałon, che seriamente ła colpise ła sałute umana, ła vegnarà elencada come un novo progeto inquinante in te ła futura.
The reporter asked if he had done the pollution detection of the plastic track. Director Song also said that the center did not directly test the pollution status of the plastic track. However, the other related products containing TDI have been tested, mainly referring to the national quality inspection. The 10 mandatory national standards issued by the General Administration in 2001, "Limited Quantity of Hazardous Substances in Interior Building Decoration Materials". This standard sets strict limits on free toluene diisocyanate in solvent-based wood coatings and adhesive products commonly used in interior architectural decoration. In addition, the center has received many reports from the public that the summer is often unpleasantly odorada da la pista de plastica de la scola adiacenteggia.
Song Guangsheng concluded that TDI is harmful to the human body. TDI is more harmful than formaldehyde and benzene. It not only has strong irritation to skin, eyes and respiratory tract, but also causes bronchitis, allergic asthma, pneumonia and pulmonary edema. After prolonged exposure or inhalation of high concentramenti de vapor TDI, l'ocio umano ga dolorose lacrime e congiuntiva congiuntiva; dopo inalazion del tratto respiratorio, ghe xe sintomi come la tosse, la streta de petto, la mancanza de fià, asma, ecc{3}}; rosse e l'erusion rosferopolare pol verificarse dopo la pelle contata.
