| 内容記述 | The third generation of artificial turf which has a longer fiber (60-65 mm in length) than those of the first and second generations, and a 40mm layer of rubber and sand infill instead of pure sand, was developed in 1998. Surface temperature on the artificial turf peaked around 65℃ by daytime in the summertime, and at the same time the surface temperature of the natural turf was around 40℃. The albedo seems to be one of the main factors in estimating the surface temperatures of outdoor sport surfaces. If the materials and the vertical structure of surfaces remain the same, we might comparatively estimate the surface temperature by using the albedo. Granulated rubber is commonly used as the rubber infill and provides the right level of shock absorbency and deformability. It was the same level on the natural turf and the artificial turf for the force reduction, which was effective in estimating the impact of the sports surfaces. There was no difference in the overall risk of injury on the third-generation artificial turf compared with natural turf. Most of the artificial turfs were sand-based and used rubber (SBR) infills that were derived from recycled used car tires. The concentrations of leaching heavy metals increased with an increase in the acidity of the acid solutions as acid rain. The concentrations of zinc (Zn) at less than 4.0 of pH, exceeded the Japanese effluent standard. The concentrations of Zn decreased with the aging of the SBR infills. The concentrations of Zn leached from SBR coated with polyurethane, ethylene-propylene rubber , Eco-fill, and cedar tree bark as an alternative of SBR were less than the Zn effluent standard in Japan. | |||||||||||||
