- Abstract:
-
Through the characteristics analysis of the heavy metals (Cr, Cu, Pb) in the soils of Yanhuai expressway embankment slope, the heavy metal pollution was evaluated. The results showed that the contents of three heavy metals in soils of different sampling areas were significantly different (P<0.05).The source of filled soil and traffic were the main causes responsible for the difference of soil heavy metal contents in sampling areas. The heavy metal contents in soils appeared the trend in general that firstly declined and then rised with increase of the distance from expressway shoulder at some certain areas. The overall contents of three heavy metals from all sampling areas were ranked from high to low as Cr>Cu>Pb. The correlation among three elements was significant (P<0.01). The potential ecological risk assessment of heavy metal pollution showed that the ecological risk degree was slight under the current situation.
