Contamination level, source, and ecological–health risk of potentially toxic elements (PTEs) and polycyclic aromatic hydrocarbons (PAHs) in the street dust of Yazd, a central capital city in Iran, were investigated for the first time regarding samples collected from 21 sites. Geochemical indices pointed out an enrichment trend of $${\text{Sb}} > {\text{Zn}} > {\text{Pb}} > {\text{Cu}} > {\text{Cd}} > {\text{As}} > {\text{Cr}} > {\text{Ni}} > {\text{V}} > {\text{Mn}} > {\text{Fe}} > {\text{Co}}$$ and an ecological risk trend of $${\text{Cd}} > {\text{As}} > {\text{Pb}} > {\text{Cu}} > {\text{Zn}} > {\text{Ni}} > {\text{Co}} > {\text{Cr}}$$ . The ecological risk indices of PAHs reflected high ecological risk for pyrene (Pyr). The statistical approach along with the isomeric ratios of PAHs suggested that the traffic-related sources, such as wearing of tires and brake pads, and the vehicular exhaust emissions were greatly responsible for the elevated concentrations of Pb, Cu, Sb, and PAHs, while Al, Ni, Co, V, Mn, As, and, to a lesser extent, Fe, Zn, Mo, and Cr were mainly influenced by geogenic sources. The human health risk assessment of PTEs and PAHs reflected that As, Cr, and Pb pose the highest non-carcinogenic risk in adults and children, compared with other PTEs and also PAHs. The carcinogenic health risk of Pb in the children and PAHs in both subpopulations was high for cancer development.
