This research evaluated the human health risk arising from exposure to heavy metals and metalloids (Al, As, Ba, Cd, Cr, Cu, Fe, Mn, Pb, Sb, V, Zn) present in the dust of the paved avenues and streets (sectors) in areas surrounding the Ventanilla Industrial Zone (ZIV) in Callao, Peru. Dust sampling was conducted on one square meter of asphalt across 16 avenues and streets within the study area. The concentrations of heavy metals and metalloids were determined using ICP-OES. Gastric bioaccessibility was assessed through the Physiologically Based Extraction Test (PBET), and bioaccessible concentrations were measured using ICP-OES. To assess the environmental quality of the site, two geochemical indices were employed: the contamination factor (CF) and the contamination load index (PLI). Human health risk analysis was conducted using the non-cancer risk index (HItotal) and the carcinogenic risk (CRtotal) for three exposure routes: oral, inhalation, and dermal. This analysis followed the methodologies of the U.S. EPA (1989) and the MINAM (2015). Results indicated that the highest total and bioaccessible concentrations of heavy metals and metalloids were found within the ZIV and its surrounding areas, particularly in the northwest direction of the ZIV, in line with the predominant wind direction. The CF and PLI analysis concluded that there is a decline in the environmental quality of the site. An unacceptable non-cancer risk classification (HItotal>1) was determined for children in 8 out of the 16 sampled sections (R2>G1>M1>V3>V1>C1>P1>P2), while an acceptable non-cancer risk was found for adults across all sections. Furthermore, it was established that there is a carcinogenic risk (CRtotal>1×10-6) in all sections due to combined exposure to As, Cd, Cr, and Pb.
