Objective: To develop an epidemiological and laboratory study to evaluate environmental exposure to lead (Pb) in two Amazonian districts. Methodology: Dom Manoel district is located near the bituminous coal processing and storage industries in the Barcarena City, Pará State, Brazil. Vila do Beja district (control) is located in Abaetetuba City and distant from these industrial areas. The epidemiological study was sectional and, in the year of 2013, blood samplings were performed, all ethical criteria being met. The Pb was quatify by induced coupled plasma mass spectrometry (ICP-MS) and certified reference materials (CRM) were used to quality control. Results: In Dom Manoel, Pb mean levels blood (N=43) were 314.90 (98.70-1001.50) μg.L-1. In this district, Pb mean levels extrapolation by age showed higher levels, 657.75 (269.72-1001.50) μg.L-1, in the range upper 60 years. In Vila do Beja (N=272), Pb mean levels decreased to 83.47 (0.99-730.60) μg.L-1. In this district, Pb mean levels were homogeneous when stratified by age group. Conclusion: The data showed that Dom Manoel people is more exposed to Pb, which may be associated with the closeness of the industrial activities of bituminous coke handling and stocking in Barcarena. The exposure may occur through the inhalation of particulate matter (dust) unfasten by this industrial plant. Vila do Beja was characterized as control district to Pb.
