内容記述 | The present study is aimed at determining the concentration of heavy metals leached from various types of rubber infills on artificial turfs by using acid solutions as a representative of acid rain. Acid solutions with pH values of 3.0, 3.5, 4.0, and 4.5 were prepared from 0.1 mol/L sulfuric acid and distilled water. Leaching was carried out according to the standard method prescribed by the Ministry of Environment in Japan. The concentrations of heavy metals such as zinc leached in the acid solutions were determined by ICP-MS method. Zinc (Zn), Iron (Fe), Barium (Ba), and Manganese (Mn) in styrene-butadiene rubber (SBR) infills were leached in acid solutions. Their concentrations increased with increasing acidity of the acid solutions. In the case of the SBR infill, the concentrations of Zn exceeded the effluent standard (2 mg/L) in Japan, but decreased with aging time, and were less than the effluent standard for aging time greater than 1.25 years. The concentrations of Zn leached from SBR coated with polyurethane (PU-SBR), ethylene-propylene rubber (EPDM), Eco-fill, and the bark of a cedar tree were less than the effluent standard of Zn in Japan, and were approximately proportional to the Zn contents (%) in all these infills except for the cedar bark. This study is also aimed at suppressing leaching zinc from infills such as SBR. The concentrations of leaching zinc increased along with the increase in the content of zinc in the infills. Chemical and physical treatments were investigated in order to remove zinc from the SBR. Sulfuric acid, sodium hydroxide, and EDTA were used for the chemical treatment, and super sonic method and conventional heating were used for the physical treatment. In the case of the SBR infills without the treatments, the leaching concentration of zinc at pH3 exceeded the effluent standard (2mg/L) in Japan. However, concentrations from the SBR infills receiving the treatments did not exceed the effluent standard. | |||||
