摘要
煤矸石可用于道路路基和基层 ,但在应用的同时需对环境造成的影响进行评价。文中根据国标《土壤环境质量标准》和《地下水质量标准》的有关指标 ,通过对宁夏地区的 3种煤矸石中的重金属含量进行检测分析 ,评价煤矸石用做路用材料时可能对环境造成的影响。
It is necessary to assess the environmental impact caused by gangue when it is used in subgrade or base courses of road.According to the national standards-'Standards of Soil Environmental Quality'and'Standards of Groundwater Quality',the environmental impact of three gangue samples from Ningxia province is assessed through determining and analyzing contents of heavy metal elements.
