Jul 01, 2009 · Epidemiologic reports of PAH-exposed workers have noted increased incidences of skin, lung, bladder, and gastrointestinal cancers. These reports, however, provide only qualitative evidence of the carcinogenic potential of PAHs in humans because of the presence of multiple PAH compounds and other suspected carcinogens.

Carbocyclic Non Benzenoid Aromatic ... General Conditions for Non-Aromatic Behavior Any compound that lacks one or more of the above features i.e. it may be acyclic / non-planar, is to be treated as non aromatic. But in this case, ‘A’ value may be even or odd number.
Aromatic compounds are unsaturated compounds having alternate double and single bonds in one or more planar rings of atoms. Benzene , a hexagon, is the simplest aromatic compound. Aromatic compounds have delocalized electrons called pi electrons that provide overall stability to these compounds. Cyclic aliphatic/non-aromatic compound (cyclobutane) In organic chemistry , hydrocarbons ( compounds composed solely of carbon and hydrogen ) are divided into two classes: aromatic compounds and aliphatic compounds ( / ˌ æ l ɪ ˈ f æ t ɪ k / ; G. aleiphar , fat, oil), also known as non-aromatic hydrocarbons.
Aromatic compounds burn with a sooty flame due to a high carbon concentration. Aliphatic compounds however means straigh-chain compounds and therefore burn depending on the functional group attached to it but I wouldnt specifically say they give off a smoky flame. Sooty/smoky is usually reserved for aromatic compounds. Aromatic amino acids are relatively nonpolar.To different degrees, all aromatic amino acids absorb ultraviolet light. Tyrosine and tryptophan absorb more than do phenylalanine; tryptophan is responsible for most of the absorbance of ultraviolet light (ca. 280 nm) by proteins. Use the following list of compounds to answer the questions below: Select the compound that is best described as: (a) A neutral, 4 p-electron, anti-aromatic system. (b) A 6 p-electron, aromatic system. (c) An aromatic system because n=2 in the Huckel 4n+2 rule. (d) A non-aromatic, conjugated 6 p-electron system
