Results are reported of a collaborative study on the determination of polycyclic aromatic hydrocarbons (PAH) including benz(a)anthracene, chrysene, benzofluoranthenes (b++k), benzo(a)pyrene, benzo(e)pyrene, and indeno(l,2,3-cd)pyrene in smoked meat. After calibration of the instrument with a standard solution, four samples of smoked meat (two of each were identical samples, respectively) were a...
The contamination of polycyclic aromatic hydrocarbons (PAHs) has become one of the major problems in the Yellow River of China. As the Yellow River is the most turbid large river in the world, it remains unknown to which extent the high suspended sediment content in the river may affect the fate and effect of PAHs. Here we report the effect of sediment on biodegradation of chrysene, benzo(a)pyr...
FVB/N mice wild-type, heterozygous or null for Cyp 1b1 were used in a two-stage skin tumor study comparing PAH, benzo[a]pyrene (BaP), dibenzo[def,p]chrysene (DBC), and coal tar extract (CTE, SRM 1597a). Following 20 weeks of promotion with TPA the Cyp 1b1 null mice, initiated with DBC, exhibited reductions in incidence, multiplicity, and progression. None of these effects were observed with BaP...
Annelation of π-conjugated frameworks has proved to be an effective way to enhance conjugation in π-conjugated polymers by eliminating conformational disorder. Upon the basis of this approach a number of ladder polymers having small band gaps and intense fluorescence have been developed.1-3 Similarly isolated fused polycyclic aromatics also serve as attractive building units.4 Considering their...
The current study was conducted to evaluate the effects of three generation sources smoke (poplar, haloxylon, and white paper), smoking duration (2 4 h) meat contents (55 80%) on Polycyclic Aromatic Hydrocarbons (PAHs) levels sausages. results showed that there are a positive correlation between lignin content PAHs level smokes smoked total in both sausages increased significantly as from 2 h. ...
