The Cd, As, Hg, Ni, and Pb contents and physicochemical properties (particle size, organic matter, pH and magnetic properties) of the bus stop dusts were investigated. Pollution levels were evaluated by the Nemero synthesis pollution index (NSPI) and geoaccumulation index (I<jats:sub>geo<\/jats:sub>). The results indicate that the magnetic susceptibilities of the bus stop dusts were higher than those in the local soils. Cd, As, Ni, and Pb contents ranged from 0.4 to 3.1, 7.1 to 16.3, 12.7 to 151.3, and 20.1 to 96.2\u2009mg\u2009kg<jats:sup>\u22121<\/jats:sup>, with average values of 1.2, 10.1, 22.2, and 44.9\u2009mg\u2009kg<jats:sup>\u22121<\/jats:sup>, while Hg content ranged from 4.5 to 1357.7\u2009\u00b5g\u2009kg<jats:sup>\u22121<\/jats:sup> with an average of 214.0\u2009\u00b5g\u2009kg<jats:sup>\u22121<\/jats:sup>. The mean contents of Cd, As, Hg, Ni, and Pb were 12.0, 0.8, 10.0, 0.6, and 2.4 times the local soil background value, respectively. Cd, Hg and Pb in approximately 96%, 62% and 19% of the bus stop dusts were above the \u201cmoderately polluted\u201d level in terms of I<jats:sub>geo<\/jats:sub>. As and Ni were defined as \u201cpractically unpolluted\u201d in all of the bus stop dusts.
