Perfluorooctane sulfonate (PFOS) is a persistent organic pollutant (POP) and emergent contaminant that are widespread in the environment. Understanding the mechanisms controlling the distribution of PFOS and its isomers between hydrargillite and the water phase is important in order to study their redistribution and mobility in the environment.

Perfluorooctanesulfonate (PFOS) is widely distributed and persistent in humans and wildlife. Prior toxicological studies have reported decreased total and free thyroid hormones in serum without a major compensatory rise in thyrotropin (TSH) or altered thyroid gland histology. Although these animals (rats, mice and monkeys) might have maintained an euthyroid state, the basis for

Prior toxicological studies have reported decreased total and free thyroid hormones in serum without a major compensatory rise in thyrotropin (TSH) or altered thyroid gland histology. Although these animals (rats, mice and monkeys) might have maintained an euthyroid state, the basis for T1 - Thyroid hormone status and pituitary function in adult rats given oral doses of perfluorooctanesulfonate (PFOS) AU - Chang, Shu Ching. AU - Thibodeaux, Julie R. AU - Eastvold, Mary L. AU - Ehresman, David J. AU - Bjork, James A. AU - Froehlich, John W. AU - Lau, Christopher. AU - Singh, Ravinder J. AU - Wallace, Kendall B Perfluoroalkyl substances (PFASs) are widely-utilized synthetic chemicals commonly found in industrial and consumer products. Previous studies have examined associations between PFASs and renal function, yet the results are mixed. Moreover, evidence on the associations of isomers of PFASs with renal function in population from high polluted areas is scant. To help to address this data gap, we Chang S, Thibodeaux J, Eastvold M, Ehresman D, Bjork J, Froehlich J, Lau C, Singh R, Wallace K and Butenhoff J (2008) Thyroid hormone status and pituitary function in adult rats given oral doses of perfluorooctanesulfonate (PFOS), Toxicology, 10.1016/j.tox.2007.10.014, 243:3, (330-339), Online publication date: 1-Jan-2008.

The IPCS (2012) has presented a continuum of the strength of evidence provided for various types of data that could suggest the occurrence of immunosuppression. In animal studies, host resistance data and immune function data (including antibody production and NK cell function) provide the strongest weight of evidence for immunotoxicity.
