Neonatal Thyroid Function in Seveso 25 Years after Maternal Exposure to Dioxin
Figure 1
Distribution of Neonatal b-TSH by Dioxin Contamination Zone
Neonatal b-TSH distribution for children born between 1994 and 2005 to women from zone A (n = 54), the zone most contaminated by TCDD after the Seveso accident; zone B (n = 425); and the surrounding noncontaminated reference area (n = 533). The graph shows kernel density estimates by zones.
*According to the WHO [1], the percentage at the population level of newborns with a b-TSH value greater than 5 μU/ml should be less than 3% in iodine-replete areas.
