(Showing whiskers): Estimated dioxin dietary intake by year (n = 15/year). Box plot of total TEQ in food by survey year 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 survey year was 2011, 0.39 (0.03–2.4); 2012, 0.57 (0.07–2.3); 2013, 0.23 (0.04–1.6); 2014, 0.34 (0.08–1.3); 2015, 0.25 (0.13–1.1); and 2016, 0.33 (0.06–1.6). Kruskal-Wallis test: χ2 = 11.25; d.f. = 5; p = 0.046. TEQ, toxic equivalents.
