had quantified bibenzyls, phenanthrenes
, and flavanones, which are used for plant identification among the Dendrobium species.
series is mainly associated with the maturity of crude oil and source rocks .
derivatives from the orchid Coelogyne cristata.
The mass chromatograms of naphthalenes, phenanthrenes
and akyl derivatives of representative coal and shale extracts from the Maastrichtian Mamu Formation in the Anambra Basin are shown in Figures 4a-b and 5a-b, respectively.
Although TWAs for specific PAHs are not given in these workplace standards, the OSHA analytical method for coal tar pitch volatiles specifies target concentrations for selected PAHs, including phenanthrene
, anthracene, pyrene, chrysene, and benzo[a]pyrene (33).
as inducers of hepatic mixed function oxygenase (MFO) in rainbow trout (Oncorhynchus mykiss).
If one assumes such shallow areas contain a mix of diesel, seep, and ValdezoiI, he says, then one can attribute much of any phenanthrenes
and chrysenes present to seep oil, and much of the dibenzothiophene signature to diesel.
. From Dendrobium officinale, nine phenanthrenes
(1-9) were isolated.
Triaromatics in aromatic fraction are mainly composed of phenanthrene
and C1-C5-alkylated phenanthrenes
Kenplast G low-viscosity mixture of alkylated naphthalenes and phenanthrenes
is an extender for epoxies, a secondary plasticizer for PVC, and a reportedly excellent compatibilizer for PVC/vinyl acetate combinations.
The identification of hopanes, steranes, n-alkanes, phenanthrenes
, dibenzotiophenes, benzocarbazols and aromatic steroids was followed by using the gas chromatography-mass spectrometry (GC-MS) analytical technique on 30 crude oils from the Marcelina (Paleocene) reservoir at the Alturitas oil field, Maracaibo Lake Basin, Venezuela.
Veeraghavan These three well produced monographs, the first on benzo [a] pyrenes and benzo [e] pyrenes, the second on cyclopenta [a] phenanthrenes
and the third on benz [a] anthracenes are companion volumes in the Cambridge Monographs series on cancer research.
