Bisphenol A levels in human urine.
The estrogenic effects of bisphenol A (BPA) have been reported in human cells (E-screen assays) and in (italic)in vivo(/italic) studies of rodents, although the latter reports remain controversial, as do the exposure levels and adverse health effects of BPA in humans. In this study we report on an analytical high-performance liquid chromatography/fluorescence method for BPA and its conjugate in...
متن کاملQuantitation of bisphenol A and bisphenol A glucuronide in biological samples by high performance liquid chromatography-tandem mass spectrometry.
Bisphenol A (BPA) is a weak estrogen. Pharmacokinetic studies of BPA have demonstrated a rapid and extensive metabolism of BPA to the nonestrogenic BPA-monoglucuronide (BPA-gluc). Some investigators have reported that BPA was found at parts per billion concentrations in the tissues or urine of humans without known exposure to BPA. This work developed a rapid and sensitive method for the determi...

Quantitation of isoprostane isomers in human urine from smokers and nonsmokers by LC-MS/MS.
A simple, rapid liquid chromatography-tandem mass spectrometry method was developed to identify and quantitate in human urine the isoprostanes iPF(2 alpha)-III, 15-epi-iPF(2 alpha)-III, iPF(2 alpha)-VI, and 8,12-iso-iPF(2 alpha)-VI along with the prostaglandin PGF(2 alpha) and 2,3-dinor-iPF(2 alpha)-III, a metabolite of iPF(2 alpha)-III. Assay specificity, linearity, precision, and accuracy met...
متن کاملMeasurement of Bisphenol-A in Human Urine by Ultra-Performance Liquid Chromatography/Tandem Mass Spectrometry
A simple and rapid ultra-performance liquid chromatographic tandem mass spectrometric assay for the measurement of bisphenol-A (BPA) in human urine was developed and validated. Sample preparation involved addition of 4-nitrophenol (as an internal standard, IS) to 1.0 ml human urine sample containing BPA, and extraction with ethyl acetate and hexane (6:4,v:v), evaporation, and dissolving the res...
