- 摘要:
- 以哈尔滨市公滨路、香成路、哈-腰堡路3条交通干道两侧的土壤为主要研究对象，用原子吸收光谱法分析土壤中重金属Cu、Cd、Pb、Zn、Cr、Ni含量，采用松嫩平原土壤重金属背景值作为参比值，应用地质累积指数法和潜在生态危害评价法对重金属污染进行评价，以研究公路交通引起的土壤中重金属污染以及潜在的生态危害。结果表明：研究区土壤中Cu、Cd、Pb、Zn、Cr、Ni的含量显著高于背景值。Cd和Pb为中等污染，土壤对重金属元素的污染程度：Zn＞Pb＞Cd＞Cr＞Ni＞Cu。污染源主要为机动车燃料、轮胎、机械中所含微量重金属成分。
- Abstract:
- With the soil which on the sides of the Harbin City road (Gongbin road，Xiangcheng road，HaYaopu road)as the main research object.The heavy metal content in each of the soil sample Cu,Cd,Pb,Zn,Cr and Ni were determined by using flame atomic absorption spectrometry.Using the index of geoaccumulation law and potential risk as well as Songnen plain background value ratio as a parameter，assessed the heavy metals on the sides of the Harbin City road.The evaluation highway traffic in the soil caused by heavy metal pollution and potential ecological harm were studied in this paper.The results showed that content of the Cu,Cd,Pb,Zn,Cr and Ni was significantly higher than the background value.Cd and Pb reached secondary pollution level.The order of heavy metals pollution was Zn>Pb>Cd>Cr>Ni>Cu.The main pollution sources were heavy metals of the motor vehicle fuel，tires，mechanical contain trace elements.
