(Showing whiskers): Estimated dioxin dietary intake by age. Box plot of total TEQ in food by age group of the ‘survey on the exposure to dioxins and other chemical compounds in humans,’ 2011 to 2016 (N = 90). The median (range) of dioxin dietary intake (in pg TEQ/kg body weight/day) by age group (year) was 24–39, 0.22 (0.08–0.54); 40–49, 0.23 (0.03–2.3); 50–59, 0.38 (0.04–2.4); and 60–77, 0.48 (0.09–1.6). Kruskal-Wallis test: χ2 = 8.87; d.f. = 3; p = 0.031. TEQ, toxic equivalents.
