Accumulation of polycyclic aromatic hydrocarbons in crankcase oil
Environmental Pollution, 1988 The concentrations of polycyclic aromatic hydrocarbons (PAHs) were measured in automotive crankcase oils. PAHs were not detected in the new oil; however, concentrations increased rapidly with usage in the gasoline engine of an automobile.

Characterization of benzopyrene metabolism in rat pancreas
Cancer Letters, 1983The present studies characterized the pancreatic metabolic system which biodegrades benzo[a]pyrene (BP), in male Sprague-Dawley rats pretreated with 20 mg/kg 3-methylcholanthrene (3MC), 75 mg/kg phenobarbital (PB) or solvent as control. Type of cytochrome involved was examined by measuring the reaction in the presence of 7,8-benzoflavone (BF), an ...

Putrescine as inhibitor of 3,4-benzopyrene cancerogenesis
European Journal of Cancer (1965), 1975Abstract The cancerogenic action of 3,4 -benzopyrene ( 3,4 -BP) can be reduced by substances physiologically occurring in organism of several animal species and human beings, as well as by a number of synthetically-prepared compounds. Experimental investigations on female mice (IMRI-strains, 4–5 weeks old, 20–25 g of body weight) have revealed ...

Synthesis of Chrysoporphyrins and a Related Benzopyrene-Fused System
The Journal of Organic Chemistry, 2022Reaction of 6-nitrochrysene with ethyl isocyanoacetate in the presence of a non-nucleophilic base gave a c-annulated pyrrole ethyl ester that was used to prepare chrysene-fused tripyrranes and a chrysopyrrole dialdehyde. Chrysene-fused tripyrranes were reacted with a pyrrole dialdehyde, but poor yields of chrysoporphyrins were obtained.

Trimer exciplex emission in benzopyrene
The Journal of Chemical Physics, 1980The authors study the emission spectra taken for 3,4,9,10-dibenzopyrene in benzene, when the main pulsed N2 laser beam (3371 Å) was used as a source of excitation.(AIP)
