Exposure of the U.S. Population to Bisphenol A and 4-tertiary-Octylphenol: 2003–2004
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. Expand
Urinary Concentrations of Bisphenol A and 4-Nonylphenol in a Human Reference Population
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. Expand
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
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. Expand
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 SurveyExpand
Urinary Concentrations of Triclosan in the U.S. Population: 2003–2004
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. Expand
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. Expand
Temporal variability in urinary concentrations of phthalate metabolites, phytoestrogens and phenols among minority children in the United States.
The reasonable degree of temporal reliability and the wide range of concentrations of phthalate metabolites, phytoestrogens and phenols suggest that these biomarkers are appropriate for use in epidemiologic studies of environmental exposures in relation to health outcomes in children. Expand
Parabens as Urinary Biomarkers of Exposure in Humans
The results, demonstrating the presence of urinary conjugates of paraben in humans, suggest that such conjugated parabens could be used as exposure biomarkers for human exposure to these compounds. Expand
Glucuronidation patterns of common urinary and serum monoester phthalate metabolites
Interestingly, the serum mEP and mBP levels were less than 3% and 47%, respectively, of their urinary levels, whereas the level of mEHP was similar both in urine and serum, which indicates that serum mBzP was largely below the method limit of detection. Expand
Quantitative detection of eight phthalate metabolites in human urine using HPLC-APCI-MS/MS.
A high-throughput, robust, sensitive, accurate, and precise assay for simultaneous measurement of trace levels of eight phthalate metabolites in human urine by HPLC-MS/MS to help elucidate potential associations (if any) between human exposure to phthalates and adverse health effects. Expand
