3-Hydroxybenzo(a)pyrene as a biomarker of dermal exposure to benzo(a)pyrene
Archives of Toxicology, 2009The aim of this study was to determine the percutaneous absorption flux of BaP (20 microg/cm(2) in ethanol) and the usefulness of urinary 3-OHBaP as a bio-indicator of dermal exposure to BaP. The percutaneous absorbed dose and absorption flux were estimated by comparison with intravenous administration of BaP (0.01 and 0.05 mg/kg in Cremophor) as ...

Pyrene and 2,7-disubstituted pyrenes have been oxidized with ruthenium(III) chloride (RuCl3) and sodium periodate (NaIO4) under very mild conditions to 4,5-diones or 4,5,9,10-tetraones. Thus, the oxidation has been controlled by varying the amount of oxidant and reaction temperature to proceed exclusively at the pyrene 4- and 5-positions or at the 4 ...

Ionization energies of benzo[a]pyrene and benzo[e]pyrene
The Journal of Chemical Physics, 1997Photoelectron spectra of benzo[a]pyrene and benzo[e]pyrene have been assigned on the basis of ab initio electron propagator theory. Electron correlation effects are included in the partial third order approximation and agreement with experimental peaks is very close.

[Transplacental effect of benz(a)pyrene and pyrene].
Biulleten' eksperimental'noi biologii i meditsiny, 1977The transplacental and direct effect of benzo(a)pyrene (BP) and pyrene on A and C57BL mice and their offspring was studied. BP proved to present blastomogenic danger for the offspring. In A mice offspring the greatest blastomogenic effect was expressed with the dose of 6 mg: lung tumours developed in 76.8% against 12.3% in the control (P less than 0 ...

The decay of benzo()pyrene and cyclopenteno(cd)pyrene in the atmosphere
Atmospheric Environment (1967), 1988Abstract The dominant source for PAH air pollution at Riso was Roskilde with 40,000 inhabitants situated 6 km south of the sampling site. Far distant sources of PAH were estimated to be insignificant. Benzo( a )pyrene and cyclopenteno(cd)pyrene were shown to decay in the atmosphere by means of the dependencies of the ratios of benzo( a ...
