Abstract We attempt to understand the pollution characteristics and carcinogenic risk of toxic elements around Hutou Village, Xuanwei City, Yunnan Province, China. For this propose, 48 road dust samples were collected systematically, and the concentrations of Cr, Ni, Cu, Zn, As, Cd, Pb, Co, and Cr(IV) were analyzed and compared; the spatial distribution was obtained. The Igeo and EF indices and multivariate statistical analysis (CA, PCA, HACA) were carried out for source investigation, and human health risk assessment was also adopted to evaluate local non-carcinogenic and carcinogenic risks. The result showed that Cr, Ni, Cu, Cd and Co contaminations were quite serious; Zn, As, Cd, and Pb had similar distribution pattern, and Cr and Ni also shared similar distribution characteristics; Cd, Pb, Zn, and As ascribed to anthropogenic sources, while Cr and Ni originated from either anthropogenic activity or natural sources; Co and Cu originated from natural sources; the non-carcinogenic risk of Co cannot be ignored. The carcinogenic risk of Ni was considered unacceptable. Finally, an indoor coal-burning pattern was established that the high Cd and Ni inhalation and ingestion model was associated with lung cancer. Keywords Toxic elements . Road dust .

Highlights 1. The pollution in the southeast of Hutou Village was more serious than that in the northeast. 2. The Cr, Ni, Cu, Cd, and Co contaminations were quite serious. 3. The source of toxic elements originated from both anthropogenic activity and natural sources. 4. The carcinogenic hazard of Ni and carcinogenic hazard of Co in Hutou Village were obvious. 5. The implications of the indoor coal-burning pattern could lead to lung cancer.
