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 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...
متن کاملMeasurement of mercury in human urine.
Four methods of determining the concentration of mercury in human urine have been studied. A simple method suitable for general laboratory use is recommended and the requirements for accurate results are defined. The method employs mild oxidation with permanganate and HS(2)O(4) followed by dithizone extraction and measurement of absorbance at 485 nm and 620 nm.No mercury was detected in any of ...
