Geometric mean blood mercury (μg/L) (95% CI) by type of seafood consumption in the past 30 d and age for US youth aged 1–19 y, NHANES 2009–2012. Total (n = 5656), 1–5 y (n = 1486), 6–11 y (n = 1943), and 12–19 y (n = 2227). Significant linear trend by age for none, any seafood, shellfish only, fish only and both fish and shellfish, P < 0.05 (pairwise comparison between the youngest and oldest age group). None is significantly different from each seafood category except for shellfish only, 1- to 5-y-olds, P < 0.05.
