To investigate the potential effects of a complex, environmentally relevant mixture on the HPT axis, sexually mature male rats were administered a mixture of 16 common organochlorines (dichlorodiphenoxytrichloroethane [DDT], p,p'-dichlorodiphenoxydichloroethylene [p,p'-DDE], hexachlorobenzene [HCB], tetrachlorodibenzo-p-dioxin [TCDD], polychlorinated biphenyls [PCBs], methoxychlor, endosulfan, heptachlor, hexachlorocyclohexane, dieldrin, aldrin, mirex, and several chlorinated benzenes, and metal contaminants [lead, cadmium]).
After 70 daily treatments by gavage, endpoints related to circulating thyroid hormone (serum thyroxine [T (4)], triiodothyronine [T (3)], thyroid stimulating hormone [TSH], and serum T (3) uptake [T (3)-up]), thyroid gland histomorphology (thyroid follicle cross sectional area, epithelial height, follicle roundness or aspect ratio, colloid/epithelial ratio) and hepatic metabolism of thyroid hormone (UDP-glucuronyl transferase [UGT] and outer-ring deiodinase [ORD]) were assessed.

In this study, the authors' objective was to determine whether serum concentrations of polychlorinated biphenyls (PCBs), hexachlorobenzene, p,p'-dichlorodiphenyl trichloroethane (DDT), o,p'-DDT, and p,p'-dichlorodiphenyl dichloroethylene (DDE) are associated with thyroid function during pregnancy.
These compounds, as well as thyroid-stimulating hormone, total thyroxine, and free thyroxine, were measured in serum samples collected between October 1999 and October 2000 from 334 pregnant women living in the Salinas Valley, California.

The current study demonstrates that only the exposure to the highest HCB dose for 30 days, has adverse effects on thyroid endpoints examined related to thyroid gland morphology, and 3,3'5,5'-tetraiodothyronine (T (4), thyroxine) serum levels, without changes in thyroid-stimulating hormone concentrations or in thyroid gland weight.

METHODS: We measured thyroid parameters [thyroid-stimulating-hormone (TSH), free thyroxine (fT (4)), total triiodothyronine (tT (3)), and thyroxine-binding globulin (TBG)] and concentrations of 41 contaminants, including PCBs and their metabolites, organochlorine pesticides (OCPs), polybrominated diphenyl ethers (PBDEs), perfluorooctanesulfonate (PFOS), and a measure of dioxin-like compounds, detected in plasma samples from Inuit adults (n = 623).
Moreover, we found negative associations between fT (4) levels and hexachlorobenzene concentrations.

BACKGROUND: It is well documented that acute exposure to high levels of persistent organic pollutants, such as polychlorinated biphenyls (PCBs), p,p'-dichlorophenyldichloroethylene (p,p'-DDE), and hexachlorobenzene (HCB), can affect human health including thyroid function.
OBJECTIVE: We investigated whether levels of PCBs, p,p'-DDE, HCB, mirex, lead, and mercury reflecting past chronic exposure are associated with alterations in levels of thyroid-stimulating hormone (TSH), triiodothyronine (T (3)), total thyroxine (TT (4)), and free thyroxine (FT (4)) among older children and adolescents.

J Occup Environ Med. 2003 May;45(5):526-32.

Thyroid volume, hypoechogenicity and nodules (by ultrasound), presence of antithyroid peroxidase (anti-TPO) antibodies, and abnormal thyroid-stimulating hormone (TSH) levels in serum (by radioimmunoassay) were examined in 101 adults from the PCB-polluted area in 360 controls.
Serum levels of PCBs, hexachlorobenzene, gamma-hexachlorocyclohexane (HCH), p,p'-DDT (1,1,1-trichloro-2,2'-bis (p-chlorophenyl) ethane), and p,p'-DDE (1,1-dichloro-2,2'-bis (p-chlorophenyl) ethene) were measured by high-resolution gas chromatography.
