Persistent organic pollutants in human breast milk and associations with maternal thyroid hormone homeostasis.
Environ. Sci. Technol. 54, 1111-1119 (2020)
Epidemiological studies have indicated the thyroid-disrupting effects of persistent organic pollutants (POPs). However, the association of low-exposure POPs with thyroid hormones (THs) remains unclear. Here, we aim to assess the association of low exposure of POPs, including polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs), and polybrominated dibenzo-p-dioxins and furans, with THs [total (L)-thyroxine (TT4), total 3,3',5-triiodo-L-thyronine (TT3), and total 3,3',5'-triiodo-(L)-thyronine (TrT3)] measured in human breast milk. Ninety-nine breast milk samples were collected from the LUPE cohort (2015-2016, Bavaria, Germany). Fourteen PBDEs, 17 PCBs, and 5 PCDD/Fs had quantification rates of >80%. Nonmonotonic associations were observed. In adjusted single-pollutant models, (1) TT4 was inversely associated with BDE-99,-154, and-196; (2) TT3 was inversely associated with BDE-47,-99,-100,-197,-203,-207, and OCDD; and (3) TrT3 was inversely associated with BDE-47, -99,-183, and -203. Multipollutant analysis using principal component analysis and hierarchical clustering revealed inverse associations of PBDEs (BDE-28,-47,-99,-100,-154,-183, and-197) with TT4 and TrT3. These results indicate that POPs at low levels might be related to reduced THs. This study shows that human breast milk might be an appropriate specimen to evaluate the thyroid disruption of POPs.
