Exposure of the U.S. Population to Bisphenol A and 4-tertiary-Octylphenol: 2003–2004
TLDR
Urine concentrations of total BPA differed by race/ethnicity, age, sex, and household income, and these first U.S. population representative concentration data for urinary BPA and tOP should help guide public health research priorities.

Urinary Concentrations of Bisphenol A and 4-Nonylphenol in a Human Reference Population
TLDR
This study provides the first reference range of human internal dose levels of BPA and NP in a demographically diverse human population and further research is needed to determine the best urinary biomarker(s) to assess exposure to NP.

Decrease in Anogenital Distance among Male Infants with Prenatal Phthalate Exposure
TLDR
The hypothesis that prenatal phthalate exposure at environmental levels can adversely affect male reproductive development in humans is supported.

Polyfluoroalkyl Chemicals in the U.S. Population: Data from the National Health and Nutrition Examination Survey (NHANES) 2003–2004 and Comparisons with NHANES 1999–2000
TLDR
The apparent reductions in concentrations of PFOS, PFOA, and PFHxS most likely are related to discontinuation in 2002 of industrial production by electrochemical fluorination ofPFOS and related perfluorooctanesulfonyl fluoride compounds.

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

Cord Serum Concentrations of Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoate (PFOA) in Relation to Weight and Size at Birth
TLDR
Despite relatively low cord serum concentrations, there are small negative associations between both PFOS and PFOA concentrations and birth weight and size and future studies should attempt to replicate these findings in other populations.

Prenatal Phenol and Phthalate Exposures and Birth Outcomes
TLDR
The association of 2,5-DCP and BP3 with reduced or increased birth weight could be important in very early or small-size births, and positive associations of urinary metabolites with some outcomes may be attributable partly to unresolved confounding with maternal anthropometric factors.

Rate of Decline in Serum PFOA Concentrations after Granular Activated Carbon Filtration at Two Public Water Systems in Ohio and West Virginia
TLDR
The observed data are consistent with first-order elimination and a median serum PFOA half- life of 2.3 years, and ongoing follow-up will lead to improved half-life estimation.

Urinary Concentrations of Triclosan in the U.S. Population: 2003–2004
TLDR
Concentrations of triclosan appeared to be highest during the third decade of life and among people with the highest household incomes and in people in the high household income categories.

Urinary levels of seven phthalate metabolites in the U.S. population from the National Health and Nutrition Examination Survey (NHANES) 1999-2000.
We measured the urinary monoester metabolites of seven commonly used phthalates in approximately 2,540 samples collected from participants of the National Health and Nutrition Examination Survey…
