Figure 6From: Long-term effects of environmentally relevant doses of 2,2',4,4',5,5' hexachlorobiphenyl (PCB153) on neurobehavioural development, health and spontaneous behaviour in maternally exposed miceThyroid hormones in serum at week16 in murine offspring. Hormone concentrations of free triiodothyronine (fT3, upper panel), free thyroxine (fT4, middle panel) and the ratio fT4/fT3 (lower panel) in pups exposed to PCB153 via gestation and lactation. The boxes show the median and the inter-quartile range. * indicates significant difference between genders (Mann-Whitney U pair wise comparison, p < 0.05).Back to article page
