Micelle-sensitized constant-energy synchronous fluorescence spectrometry for the simultaneous determination of pyrene, benzo[a]pyrene and perylene.
The use of micellar media in constant-energy synchronous fluorescence spectrometry has been proposed. The influence of some aqueous micellar systems on the determination of pyrene, perylene and benzo[a]pyrene has been investigated. The presence of these micellar systems allows their determination in aqueous media, thus avoiding the use of an organic solvent, and greatly enhances the fluorescenc...
متن کاملInhibition of Benzo(a)pyrene and Benzo(a)pyrene 7,8-Dihydrodiol Metabolism by Benzo(a)pyrene Quiñones1
Benzo(a)pyrene 1,6-, 3,6-, and 6,1 2-quinones were found to be noncompetitive inhibitors of mixed-function oxidation of benzo(a)pyrene (BP) and frans-7,8-dihydro-7,8-dihydroxybenzo(a)pyrene (BP 7,8-dihydrodiol). BP 6,1 2-quinone was the most potent inhibitor of both BP and BP-7,8-dihydrodiol oxi dation followed by BP 1,6-quinone and BP 3,6-quinone. The K, for inhibition of BP mixed-function oxi...

متن کاملValidation of an Analytical Method for Determination of Benzo[a]pyrene Bread using QuEChERS Method by GC-MS
A fast and simple modified QuEChERS (quick, easy, cheap, rugged and safe) extraction method based on spiked calibration curves and direct sample introduction was developed for determination of benzo[a]pyrene (BaP) in bread by gas chromatography-mass spectrometry single quadrupole selected ion monitoring (GC/MS-SQ-SIM). Sample preparation includes extraction of BaP into acetone followed by clean...
