    POLYCYCLIC AROMATIC HYDROCARBON (PAH)

    Polycyclic aromatic hydrocarbons (PAHs), also known as poly-aromatic

    hydrocarbons or polynuclear aromatic hydrocarbon, are potent atmospheric

    pollutants that consist of fused aromatic rings and do not contain heteroatoms or

    carry substituents. Naphthalene is the simplest example of a PAH. PAHs occur

    in oil, coal, and tar deposits, and are produced as byproducts of fuel burning

    (whether fossil fuel or biomass). As a pollutant, they are of concern because some

    compounds have been identified as carcinogenic, mutagenic, and teratogenic.

    PAHs are also found in cooked foods. Studies have shown that high levels of

    PAHs are found, for example, in meat cooked at high temperatures such as

    grilling or barbecuing, and in smoked fish.

    As for the kinds of polyaromatic hydrocarbons:

    AcenaphtheneAcenaphthene is a polycyclic aromatic hydrocarbon (PAH) consisting

    ofnaphthalene with anethylene bridge connecting positions 1 and 8. An

    alternative name, 1,2 dihydroacenaphthylena, emphasizes that it is a hydrogenated

    form ofacenaphthylene. It is a constituent ofcoal tar.Acenaphthene was prepared

    the first time from coal tar by Marcellin Berthelot and after that with Bardy he

    synthesized it from -ethyl naphthalene.It is used in preparation of dyes,

    pesticides and pharmaceuticals.It does not appear to be carcinogenic.

    AcenaphthyleneAcenaphthylene is a polycyclic aromatic hydrocarbon consisting

    ofnaphthalene with an ethylene bridge connecting positions 1 and 8. It is a

    constituent ofcoal tar. Reduction of the ethylene group gives the related

    compound acenaphthene.Unlike most polycyclic aromatic hydrocarbons, it has

    no fluorescence.

    Benz[a]anthracene

    benzo[a]pyreneBenzo[a]pyrene (C20H12) is a five-ring polycyclic aromatic

    hydrocarbon whose metabolites aremutagenic and highly carcinogenic.

    Benzo[a]pyrene is listed as a Group 1 carcinogen by theIARC. It belongs to a

    class of polycyclic aromatic compounds known as benzopyrenes, which consist of

    a benzene ring fused to a pyrene molecule. Benzo[a]pyrene is a product of

    incompletecombustion at temperatures between 300 and 600C. Benzo[a]pyrene

    was determined in 1933 to be the component ofcoal tar responsible for the first

    recognized occupation-associated cancers, the sooty warts (cancers of

    the scrotum) suffered by chimney sweeps in 18th century England. In the 19th

    century, high incidences ofskin cancers were noted among fuel industry workers.

    By the early 20th century, the toxicity of benzo[a]pyrene was demonstrated

    whenmalignant skin tumors were produced in laboratory animals by repeatedly

    painting them withcoal tar.

    The name "chrysene" originates from Greeko(chrysos), meaning

    "gold", and is due to the golden-yellow color of the crystals of the hydrocarbon,

    thought to be the proper color of the compound at the time of its isolation and

    characterization. However, high purity chrysene is colorless, the yellow hue being

    due to the traces of its yellow-orange isomer tetracene, which cannot be separated

    easily. Related compounds chrysene is Pyrene, Tetracene,Triphenylene

    CoroneneCoronene (also known as superbenzene) is a polycyclic aromatic

    hydrocarbon (PAH) comprising six peri-fused benzene rings.[1]

    It is a yellow

    material that dissolves in such solvents as benzene, toluene, and dichloromethane.

    Its solutions emit blue light fluorescence under UV light. Its emission spectrum is

    not symmetrical with its excitation spectrum and varies in the number of bands

    and their relative intensities depending on the solvent. It has been used as a

    solvent probe, similar to pyrene.

    It occurs naturally as the mineral carpathite, which is characterized by flakes

    of pure coronene embedded in sedimentary rock. This mineral may result from

    ancient hydrothermal vent activity.

    Coronene is produced in the petroleum refining process of hydrocracking, where

    it can dimerize to a fifteen ring PAH, trivially named "dicoronylene" (formally

    named benzo[10,11]phenanthro[2',3',4',5',6':4,5,6,7]chryseno[1,2,3-bc]coronene

    or benzo[1,2,3-bc:4,5,6-b'c']dicoronene). Coronene has been seen on the surface

    ofTitan (Saturn's moon). It can cause DNA damage in mammals.

    The compound is of theoretical interest to organic chemists because of

    its aromaticity. It can be described by 20 resonance structures or by a set of three

    mobile Clar sextets. In the Clar sextet case the most stable structure for coronene

    has only the three isolated outer sextets as fully aromatic

    although superaromaticity would still be possible when these sextets are able to

    migrate into the next ring.

    FluorantheneFluoranthene is a polycyclic aromatic hydrocarbon (PAH) consisting of

    a naphthalene and abenzene unit connected by a five-membered ring. It is a

    member of the class of PAHs known as non-alternant PAHs because it has rings

    other than those with six carbon atoms. It is a structural isomer of the alternant

    PAH pyrene. It is not as thermodynamically stable as pyrene because its electrons

    cannot resonate throughout the complete structure as the corresponding ones in

    pyrene.

    Fluoranthene is found in many combustion products, along with other PAHs.

    Its presence is an indicator of less efficient or lower-temperature combustion,

    since non-alternant PAHs are less preferred in formation than alternant PAHs.

    Fluoranthene is one of the U.S. Environmental Protection Agency's 16 priority

    pollutant PAHs and is a carcinogen.

    Fluoranthene has been isolated from coal tar pitch. Its name is derived from

    its fluorescenceunder UV light.

    purposes it is obtained from coal tar. It is insoluble in water and soluble

    in benzene and ether.

    Fluorene is a precursor to other fluorene compounds; the parent species has

    few applications. Fluorene-9-carboxylic acid is a precursor to pharmaceuticals. 2-

    Aminofluorene, 3,6-bis-(dimethylaminofluorene), and 2,7-diiodofluorene are

    precursors to dyes. Oxidation of fluorene gives fluorenone, which is nitrated to

    give commercially useful derivatives. 9-Fluorenylmethyl chloroformate (Fmoc

    chloride) is used to introduce the 9-fluorenylmethyl carbamate (Fmoc)protecting

    group on amines in peptide synthesis.[2]

    Polyfluorene polymers (where carbon 7 of one unit is linked to carbon 2 of

    the next one, displacing two hydrogens) are electrically

    conductive and electroluminescent, and have been much investigated for use as

    a luminophore in organic light-emitting diodes.

    Polycyclic Aromatic Hydrocarbon Analysis (PAH)

    Polycyclic Aromatic Hydrocarbon (PAH) analysis is a quantitative

    technique used for the determination of PAHs (parent compounds and

    homologues) in extracts of sediment, water, and tissue. PAH analysis is performed

    using gas chromatography / mass spectrometry (GC/MS) in selected ion

    monitoring (SIM) mode. Method detection limits for PAHs using this method are

    extremely.

    The GC is temperature programmed, operated in splitless mode, and carrier

    flow is by electronic pressure control. The capillary column is a J&W DB-

    5MS

    (60 m long by 0.25 mm ID and 0.25 mm film thickness) or equivalent. The

    data acquisition system allows continuous acquisition and storage of all data

    during analysis and is capable of displaying ion abundance versus time or scan

    number.

    A sample batch is analyzed as an analytical set including samples along

    with the following specified quality control samples: method-blank, matrix-spike,

    duplicate, matrix-spike duplicate, and standard reference material.

    A calibration curve is established by analyzing each of five calibration

    standards (analyte concentrations ranging from 0.02 to 1 mg/mL) and determining

    a relative response factor (RRF) for each analyte. Calibration check standards are

    interspersed throughout an analytical batch in order to insure the instruments

    integrity. A diluted oil standard is used as a retention index solution for

    compounds not found in the calibration solution. Analyte concentrations are

    determined using the internal standard method and analyte concentrations are

    corrected for surrogate recovery.
