Concentrations, sources and ecological–health risks of potentially toxic elements in finer road dust from a megacity in north China

Finer road dust has attracted considerable attention due to its more serious environmental detriment and ecological–health risk than coarser road dust. In this study, the concentrations of nine potentially toxic elements (PTEs, i.e. As, Co, Cr, Cu, Hg, Mn, Ni, Pb, and Zn) were analyzed in finer road...

Zusammenfassung:	Finer road dust has attracted considerable attention due to its more serious environmental detriment and ecological–health risk than coarser road dust. In this study, the concentrations of nine potentially toxic elements (PTEs, i.e. As, Co, Cr, Cu, Hg, Mn, Ni, Pb, and Zn) were analyzed in finer road dust with particle size
