PurposePerfluoroalkyl substances (PFASs) are environmentally persistent amphiphilic compounds. Exposure to two PFASs, perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) is linked to specific occupations and industries. This study examines the contribution of past occupational PFAS exposure to serum PFOS and PFOA levels among 154 older adults in New York State.MethodsSerum PFOS and PFOA levels were compared to data from the National Health and Nutrition Examination Survey… 

Perfluoroalkyl Chemicals and Male Reproductive Health: Do PFOA and PFOS Increase Risk for Male Infertility?

The current epidemiological studies linking increased exposure to PFAS with lowered testosterone and semen quality, and evidence from rodent studies supporting their function as endocrine disruptors on the reproductive system, exhibiting non-monotonic dose responses, are noted.

Prenatal Perfluorooctanoic Acid (PFOA) Exposure Is Associated With Lower Infant Birthweight Within the MADRES Pregnancy Cohort

Prenatal exposure to PFOA was associated with lower birthweight in infants, suggesting that exposure to these chemicals during critical periods of development might have important implications for children's health.

Assessment of the Emerging Threat Posed by Perfluoroalkyl and Polyfluoroalkyl Substances to Male Reproduction in Humans

The literature on the biological effects of PFAS exposure is reviewed, with a specific focus on male reproduction, owing to its utility as a sentinel marker of general health and the mechanisms that render the male reproductive tract vulnerable to PFAS mediated damage.

Nexus between perfluoroalkyl compounds (PFCs) and human thyroid dysfunction: A systematic review evidenced from laboratory investigations and epidemiological studies

This review summarizes the underlying evidence on the primary fate and in which PFCs have an endocrine-disrupting potential in relation to drinking water supplies.

High levels of both PFAS exposure and COVID-19 were found in the oldest populations, while this does not determine causality, and such associations should help promote further study.

This paper synthetizes the current literature reports on the presence, bioaccumulation and, particularly, endocrine toxicity of selected long- and short-chain PFASs, with a special emphasis on the mechanisms underlying their endocrine actions.

Perfluoroalkyl Substances and Metabolic Syndrome in Firefighters: A pilot study.

Current serum PFASs in FF are not associated with MetS risk, and compared to US general population, an elevated risk of hypertension was noted in FF, but no significant association betweenPFASs and MetS was found.

Increased toxicity and retention of Perflourooctane Sulfonate (PFOS) in humanized CYP2B6-Transgenic mice compared to Cyp2b-null mice is relieved by a High-Fat Diet (HFD).

Serum Perfluorooctanoate (PFOA) and Perfluorooctane Sulfonate (PFOS) Concentrations and Liver Function Biomarkers in a Population with Elevated PFOA Exposure

A positive association between PFOA and PFOS concentrations and serum ALT level, a marker of hepatocellular damage is shown, and the relationship with bilirubin appears to rise at low levels of PFO a and to fall again at higher levels.

Biomonitoring of Perfluorinated Compounds in Children and Adults Exposed to Perfluorooctanoate-Contaminated Drinking Water

Regression analysis showed that age and male sex were significant predictors of PFOS, PFOA, and PFHxS; associations of other regressors (diet, body mass index) varied among PFCs.

Trends in exposure to polyfluoroalkyl chemicals in the U.S. Population: 1999-2008.

These NHANES data suggest that sociodemographic factors may influence exposure and also provide unique information on temporal trends of exposure, and additional research is needed to identify the environmental sources contributing to human exposure to PFCs.

Association between Serum Perfluorooctanoic Acid (PFOA) and Thyroid Disease in the U.S. National Health and Nutrition Examination Survey

Higher concentrations of serum PFOA and PFOS are associated with current thyroid disease in the U.S. general adult population and more work is needed to establish the mechanisms involved and to exclude confounding and pharmacokinetic explanations.

Tracking the pathways of human exposure to perfluorocarboxylates.

A one-compartment pharmacokinetic model used to back-calculate daily intakes from serum levels is shown to provide agreement within a factor of 1.5-5.5 of the daily intakes derived from exposure media, which provides supporting evidence that dietary exposure is a major ongoing exposure pathway of PFOA to the background population.

Community Exposure to Perfluorooctanoate: Relationships Between Serum Concentrations and Exposure Sources

Household water source was the primary determinant of serum (PFOA), and occupational exposure from production processes using PFOA and residential water had additive effects; no other occupations contributed.

Serum concentrations of 11 polyfluoroalkyl compounds in the u.s. population: data from the national health and nutrition examination survey (NHANES).

The concentrations of most PFCs were similar regardless of the participants' ages but were higher in males than in females, and higher education was associated with higher concentrations of PFOS and PFOA.

This investigation randomly sampled a fluorochemical manufacturing employee population to determine the distribution of serum fluorochemical levels according to employees' jobs and work areas, and found the geometric means were approximately one order of magnitude higher than those observed for the film plant employees.

Association between serum perfluorinated chemicals and thyroid function in U.S. adults: the National Health and Nutrition Examination Survey 2007-2010.

Higher serum concentrations of PFOA and PFHxS are associated with total T3, total T4, and free T4 in the U.S. general population, and more studies are warranted to clarify the causal relationship.
