It's a man-made chemical from the polycyclic hydrocarbon family.
The bicyclic polycyclic aromatic compounds have lower solubility and vapor pressure.
The carbon monoxide in his tissue had traces of naphthalenes and polycyclic aromatics.
No wonder polycyclic aromatic hydrocarbons can be found in coal, oil and even food.
It's certainly consistent with prolonged exposure to benzene and polycyclic hydrocarbons commonly associated with oil development.
Polycyclic Aromatic Hydrocarbons(PAH) constitute a small proportion of this particulate matter.
Laboratory studies also suggest that both polycyclic musks and nitromusks may affect hormone systems[14-19].
However, polycyclic aromatic compounds are often found on suspended particles in the air.
It is quite analogous to LSD, and it has been named for itspropionyl group that is bound to the nitrogen of polycyclic indole group.
Polycyclic aromatic compounds above three rings have low solubility and low vapor pressure in water.
For instance, carcinogenic chemicals that form duringmeat processing include N-nitroso compounds and polycyclic aromatic hydrocarbons.".
Studies indicate that both‘polycyclic musk' and‘nitromusk' can affect the hormonal systems(13-16).
A molecule containing one or more rings is called a cyclic compound, and a molecule containing two or more rings(either in the same or different ring systems)is termed a polycyclic compound. A molecule containing no rings is called an acyclic or open-chain compound.
(2004): Degradation of polycyclic aromatic hydrocarbons in aqueous solutions by ultrasonic irradiation.
(2011): Comparison of extraction and clean-up techniques for the determination of polycyclic aromatic hydrocarbons in contaminated soil samples.
Polycyclic aromatic compounds are therefore more commonly found in the soil and in sediments than in water and air.
When the molecular weight is increased, the carcinogenicity of the polycyclic aromatic compound is also increased, and the acute toxicity is decreased.
Polycyclic aromatic compounds can destroy genetic material in the body, trigger the growth of cancer cells and increase the incidence of cancer.
Artificial Musk oil contains two main groups- nitromusks, polycyclic musks- substances that accumulate in the body and are often found during blood and breast milk tests(6-9).
Cooking of red meat or processed meat also produces heterocyclic aromatic aminesas well as other chemicals including polycyclic aromatic hydrocarbons, which are also found in other foods and air pollution.
P-LSD contains a polycyclic group that features the bicyclic Hexahydro indole bound to its quinolone bicyclic group.
Massachusetts Institute of Technology professor William Green said it has long been speculated that pathways involvingresonantly-stabilized radicals might be important in polycyclic aromatic hydrocarbon(PAH) and soot formation, since the known reactions are not fast enough to explain the rapid formation of soot.
For the sonochemical degradation of polycyclic aromatic hydrocarbons(PAHs) naphthalene, acenaphthylene and phenanthrene in water, sample mixtures were sonicated at 20◦C and 50 µg/l of each target PAH(150 µg/l of total initial concentration).
Typically a"ring" denotes a simple ring, unless otherwise qualified, as in terms like"polycyclic ring","fused ring","spiro ring" and"indole ring", where clearly a polycyclic ring system is intended. Likewise, a"ring system" typically denotes a polycyclic ring system, except in terms like"monocyclic ring system" or"pyridine ring system". To reduce ambiguity, IUPAC's recommendations on organic nomenclature avoid the use of the term"ring" by using phrases such as"monocyclic parent" and"polycyclic ring system".
