Gaertner, Platanus orientalis L., Salix babylonica L.]. Samples were collected from 28 points distributed over 5 sites representing different traffic intensities in the city of Zonguldak. The relationships of sampling sites were determined using the UPGMA method. According to the results of analyses, the trace element and S concentrations in the observed tree species were ordered as follows: S>Mg>Fe>Sr>Zn>B>Ba>Al>Mn>Cu>Pb> Ni> V>Cr>Li>Co>Cd in Alnus glutinosa; S>Mg>Fe>Sr>Zn> Mn> Ba >Al>B>Cu>Pb>Cr>V>Li>Ni>Co>Cd in Platanus orientalis; S>Fe>Mg>Zn>Sr>Al>Ba>B>Mn>Cu> V>Pb>Ni>Li>Cr>Cd>Co in Salix babylonica. Significant positive correlations existed between the amount of heavy metals (r=0.81-1.00). The results are discussed in the context of prior studies.eninfo:eu-repo/semantics/closedAccessHeavy metalZonguldakTree leavesArticle187B12431248N/AWOS:000269871900002Q4
