Concentrations of metallic elements,N and S in Sabina chinensis cvpyramidalis leaves along urban-rural roadways of Nanjing city

Abstract

Abstract: This paper measured the concentrations of metallic elements,N and S in soils and Sabina chinensis cv.pyramidalis leaves along the urban-rural roadways (urban trunk roads,belt highway,and suburban roads) of Nanjing city,with botanical garden as un-traffic impacted reference site,and discussed the transfer of test elements among atmosphere,plant and soil,as well as the impact of traffic- related pollution.The results showed that the concentrations of Al,Fe,Mo,Zn,Cd,Pb,As and Cr in Sabina chinensis leaves were significantly higher along urban-rural roadways than at reference site,being most remarkable for Al,Fe,Mo and Zn.The positive correlations between soil and Sabina chinensis leaf Fe,Zn and As concentrations in road environment indicated that Sabina chinensis might be a good indicator plant of soil Fe,Zn and As.The correlations between soil and plant leaf Al,Mo,Cu,Pb,Cd and Cr concentrations were not remarkable,and thus,their high concentrations in Sabina chinensis leaf in road environment might be caused by air pollution.The concentrations of N and S in Sabina chinensis leaf were higher along urban trunk roads and belt highway than at reference site,while those along suburban roads were similar to the reference.There was a negative correlation between soil and plant leaf N,and a positive correlation between soil and plant leaf S.The N content in roadside soil was lower,while the S content was higher than the reference,indicating that the higher Sabina chinensis leaf N content in road environment might be caused by the NO_x from exhaust gas emission,and the higher leaf S content should be come from soil.

Key words: Road traffic pollution, Environmental elements, Phytoindication
