在日本,由于高速铁路牵引接触网和电动车组受电弓接触,致使高速铁路的沿线受到污染。主要污染物质是铜和锡。经测试,目前在高速铁路沿线地区,这两种物质的含量都超过允许的标准。日本国家环境机构提供了污染状况,具体统计数字是:锡含量是允许标准值的8—18倍。这个含量毒性比较大,使高速铁路沿线居民受到严重威胁。和允许的标准铜含量相比,离轨道10m的表层土壤的铜含量为4—14倍;稻、谷物和其他植物的铜含量为2—3倍;空
In Japan, the high-speed railway was polluted along the pylon due to the high-speed railway traction catenary and the electric train contact. The main pollutants are copper and tin. Tested, at present in the area along the high-speed railway, the content of these two substances exceed the allowable standard. Japan’s national environmental agency provided pollution status, the specific statistics are: tin content is allowed 8-18 times the standard value. This content is relatively toxic, causing serious threat to residents along the high-speed railway. Compared with the allowable standard copper content, the copper content of topsoil 10m away from the track is 4-14 times; the content of copper in rice, grain and other plants is 2-3 times;
