Objective: To evaluate the environmental exposure to cadmium (Cd) in children of population that live close to industrial areas in Amazon. Methods: The study was sectional with quantitative approach. This was done in children (1 to 12 years old), that live in Bairro Industrial (BIN) district, near the kaolin processing industry, and Vila de Beja (VBJ) district (control), about 10 km, both in neighboring cities (Barcarena and Abaetetuba) and located in the Pará State, Northern of Brazil. The sampling (N=117) was performed in 2013. Blood was used to quantify Cd and the population was stratified in age groups: ≤ 2 years, 3 to 5 years, 6 to 9 years and 10 to 12 years. The Cd in blood was quantify by induced coupled plasma mass spectrometry (ICP-MS). Results: The Cd mean levels in BIN were 0.65 (0.07-2.93) μg.L-1 and the highest levels (0.96, N=8) were between infants (≤ 2 years) and those (0.74, N=15) in early adolescence (10 to 12 years). In VBJ, the levels were 0.44 (0.07-1.74) μg.L-1 and the highest levels in the 3 to 5 years (0.53, N=15) and ≤ 2 years (0.50, N=5) ranges. Conclusion: The Cd mean levels was significantly higher in BIN when compared to VBJ (p=0.032). In both districts the Cd levels in infants were higher, with a significant reduction between 3 and 5 years and increase after 6 years. Transfers from mother to child may be occurring through breastfeeding.
