In order to understand the urban road sediment pollutants concentration levels and possible ecological environmental hazards,urban road sediment samples were monitored and analyzed from four different functional areas including the living areas,the educational areas,the traffic routes and the green parks in the city of Beijing.Total nitrogen(TN),total phosphorus(TP),heavy metals and organic matter(TOC) in the road sediments were tested in order to get the pollutant characteristics.The research results show that high levels of TN,TP,and TOC are found in all types of road sediments.TN concentration in the road sediments in the living areas,the educational areas,the traffic routes and the green parks are 0.1009、0.1440、0.1071、0.0974mg/kg,respectively,which is significantly the most highest in the educational areas.TP concentration in the four areas are 0.0695、0.0729、0.0665、0.0608mg/kg,respectively,which is the most highest in the educational areas but not reach a significant level.Concentrations of TOC in sediments in the traffic routes and educational areas are found significantly higher than that in the living areas and the green parks.And heavy in the traffic routes,educational areas and the living areas are found much higher than that in the green parks.Human activities and traffic vehicles may be the main dominent factors.Dissolved nitrogen is the main form of nitrogen in the four fonction areas,but phosphorus is mainly in particles,and this is most significant in sediments in the traffic routes.Dissolved heavy metal content is low overall,and only dissolved Cu accounts above 5 percent in the total ammount.This indicates heavy metals are mainly in particles.Road sediments or outside solid substances are the important source of surface runoff pollutants.The findings of the paper provide important reference for the urban surface pollution control.
