Abstract

We investigated the 123 male children from Ahvaz, average age 7.56, and its relation with metalloids' levels in children's blood. In this study, seven metalloids (As, Cd, Cr, Co, Hg, Ni and Pb) in children blood were measured and calculated non-cancer and cancer risks due to metalloids exposure atmosphere regions including industrial (Padad), vehicle traffic (Golestan) and reference (Kianpars). The higher concentrations of metals in the Padad ambient air As, Cd, Co, Cr, Hg and Ni coincided with the higher concentrations of the same metals in exposed children (P < 0.05) versus the reference. Children in Golestan had the highest blood lead concentrations (P < 0.05). Non-cancer risk (HIinhal) of atmospheric metalloids in the Padad were 1.78 times (P < 0.001) and cancer risk (ILCRinhal) assigned to As, Co, Cd and Ni were 112.1, 1.66, 1.81 and 1.55 times, respectively higher than those of Kianpars. The spatial distribution of children's blood metalloids concentrations showed an abnormal increase of 12–35 ng/mL, 5–10 ng/mL, 15–35 ng/mL, 5–10.5 μg L−1, 1–3.5 μg L−1 and 12–40 ng/mL for BAs, BCd, BCo, BCr, BHg and BNi respectively in the industrial area which children in the industrial area are prone to chronic diseases. © 2022
