Geometric mean toxic metal concentrations in infants/children grouped by age and their mothers. (a) Mercury, (b) Arsenic, (c) Lead, (d) Cadmium, (e) Aluminum. Infants/children were grouped by age; 0–3, 4–9, and 10–11 year-old, and the geometric mean concentrations of toxic metals in each group were compared to those in their mothers. Statistically significant difference in the mean value in each age-group compared to their mother group is shown with asterisk marks: * p < 0.05, ** p < 0.01, **** p < 0.0001.
