Concentrations of Hg in maternal hair and blood, placenta, and cord blood in study participants from Croatia, continental (▲) and coastal area (●), related to the frequency of seafood (fish) consumption per week. Subgroups (number of participants is given in Table 1, except the number of analyzed hair samples in the continental area indicated here in parentheses): 0—no consumption (n = 11); 1—consumption ≤1 per week (n = 34); 2—consumption >1–2 per week (n = 20); 3—consumption >2 per week (n = 6). Data are presented as the median and interquartile range (25–75%). Statistically significant differences (p < 0.05) between the subgroups tested by one-way ANOVA and post hoc Bonferroni test are indicated by different letters.
