锶渣路基重金属污染特征及风险评估
Heavy metal pollution characteristics and risk assessment of strontium slag roadbed
摘要
Abstract
In order to realize the resource utilization of strontium slag,based on the concept of"treating waste with waste",lime was used as curing agent to solidify strontium slag,and roadbed filling materials were prepared.The pol-lution characteristics of seven heavy metals(Sr,Ba,Cr,Ni,Zn,As,Cd)in strontium slag roadbed were analyzed,and their potential ecological risks and human health risks were evaluated.The results show that the mass fractions of Sr and Ba in the strontium slag subgrade are higher,which are 88 500.3 mg/kg and 3 360.2 mg/kg,respectively,and the mass fractions of the other five heavy metals are low,indicating that the main characteristic metals in the stronti-um slag subgrade are Sr and Ba;the overall ecological risk of strontium slag roadbed is high,and Sr and Cd are the main ecological risk contribution factors,accounting for 97.6％of the total ecological risk contribution.The carcino-genic risk and non-carcinogenic risk of strontium slag roadbed are within the acceptable range,indicating that the health risk of strontium slag roadbed to human body is controllable.关键词
