Definition of Polycyclic aromatic hydrocarbon:
Polycyclic aromatic hydrocarbon (PAH), any of several multi-ringed aromatic compounds that are found in e.g. soot, coal, tar, cigarette smoke and barbecue meat. Examples include pyrene and benzo(a)-pyrene. Some of these compounds are known carcinogens. [1]
This is the common definition for Polycyclic aromatic hydrocarbon, other definitions can be discussed in the article



Fluoranthene and pyrene = Major PAH followed by phenanthene and anthracene acenaphtene fluorene benzanthrene and chrysene in few samples


[2]


Food primary source of PAH's, and PAH levels are diet dependent.


PAHs are released by the combustion of wood, coal and oil and transported into the admosphere. Some PAHs are considered carcinogenic in fish, others might not be. [3]
