Combustible under specific conditions.
... Using recently developed metabolic toxicity screening arrays and a biocolloid reactor-LC-MS/MS approach, both featuring films of DNA and human metabolic enzymes, we demonstrated the relatively low reactivity of metabolically activated benzo[ghi]perylene (B[ghi]P) toward DNA. Electro-optical toxicity screening arrays showed that B[ghi]P metabolites damage DNA at a 3-fold lower rate than benzo[a]pyrene (B[a]P), whose metabolites have a strong and well-understood propensity for DNA damage. Metabolic studies using magnetic bead biocolloid reactors coated with microsomal enzymes in 96-well plates showed that cyt P450s 1A1 and 1B1 provide high activity for B[ghi]P and B[a]P conversion. Consistent with published results, the major metabolism of B[ghi]P involved oxidations at 3,4 and 11,12 positions, leading to the formation of B[ghi]P 3,4-oxide and B[ghi]P 3,4,11,12-bisoxide. B[ghi]P 3,4-oxide was synthesized and reacted with deoxyadenosine at N6 and N7 positions and with deoxyguanosine at the N2 position. B[ghi]P 3,4-oxide is hydrolytically unstable and transforms into the 3,4-diol or converts to 3- or 4-hydroxy B[ghi]P. LC-MS/MS of reaction products from the magnetic biocolloid reactor particles coated with DNA and human enzymes revealed for the first time that a major DNA adduct results from the reaction between B[ghi]P 3,4,11,12-bisoxide and deoxyguanosine. Results also demonstrated 5-fold lower formation rates of the major DNA adduct for B[ghi]P metabolites compared to B[a]P. Overall, results from both the electro-optical array and biocolloid reactor-LC-MS/MS consistently suggest a lower human genotoxicity profile of B[ghi]P than B[a]P.
Carcinogenic polycyclic aromatic hydrocarbons (PAH), e.g., benzo[a]pyrene (BaP), possess a bay region comprising an ortho-fused benzene ring. Benzo[ghi]perylene (BghiP) represents the group of PAHs lacking such a "classic" bay region and hence cannot be metabolically converted like BaP to bay region dihydrodiol epoxides considered as ultimate mutagenic and carcinogenic metabolites of PAH. BghiP exhibits bacterial mutagenicity in strains TA98 (1.3 his(+)-revertant colonies/nmol) and TA100 (4.3 his(+)-revertant colonies/nmol) of Salmonella typhimurium after metabolic activation by the postmitochondrial hepatic fraction of CD rats treated with 3-methylcholanthrene. Inhibition of microsomal epoxide hydrolase (mEH) with 1,1,1-trichloro-2-propene oxide raised the bacterial mutagenicity of BghiP in TA98 almost 4-fold indicating arene oxides as ultimate mutagens. To confirm this assumption, the biotransformation of BghiP was elucidated. Incubation of BghiP with liver microsomes of CD rats treated with Aroclor 1254 yielded 17 ethyl acetate extractable metabolic products. Twelve metabolites were identified by a combination of chromatographic, spectroscopic, and biochemical methods. The microsomal biotransformation of BghiP proceeds by two pathways: Pathway I starts with the monooxygenase attack at the 7-position leading to the 7-phenol, which is transformed to the 7,8- and 7,10-diphenols followed by oxidation to the 7,8- and 7,10-quinones. On pathway II, the K regions of BghiP are successively converted to arene oxides yielding the indirectly identified 3,4-oxide and the 3,4,11,12-bisoxides. Enzymatic hydrolysis of the 3,4-oxide leads to the trans-3,4-dihydrodiol, which is oxidized to the 3,4-quinone. Similarly, the trans-3,4-trans-11,12-bisdihydrodiols and the trans-3,4-dihydrodiol 11,12-quinone are generated from the 3,4,11,12-bisoxides. The trans-3,4-dihydrodiol and the trans-3,4-trans-11,12-bisdihydrodiols are preferentially formed as R,R and R,R,R,R enantiomers, respectively. The intrinsic bacterial mutagenicity of the 3,4,11,12-bisoxides is rather low and hardly explains the strong increase in bacterial mutagenicity of BghiP after inhibition of mEH. Thus, we believe that the 3,4-oxide plays a more important role as the ultimate mutagenic metabolite of BghiP.

This research program was conducted to determine the capability of biological treatment and activated carbon desorption to remove chemical carcinogens and other hazardous organic cmpd (including benzo(ghi)perylene) from water and wastewater. All cmpd tested exhibited some degree of biological degradation. Carbon adsorption was also effective in removing the cmpd from aqueous solutions. Large polynuclear aromatic compounds exhibited reduced adsorption capacities due to exclusion from the small diameter pores of the carbon.

In an analysis of 33 human placenta samples collected from non-smoking women in Beijing, China during 2005-2006, benzo(ghi)perylene was detected at mean, median, minimum and maximum concentrations of 0.098, 0.118, not detectable and 0.244 ng/g fresh weight respectively(1). In an analysis of 7 human umbilical blood samples collected from non-smoking women in Beijing, China during 2005-2006, benzo(ghi)perylene was detected at mean, median, minimum and maximum concentrations of 0.014, 0.036, not detectable and 0.170 ng/g fresh weight respectively(1).

Lower dose group had first papilloma in 238 days, with papillomas in 19 mice and squamous carcinomas in 10 mice; the higher dose group had first papilloma in 222 days, with papillomas in 20 mice and squamous carcinomas in 18 mice. No effects were observed in benzo(ghi)perylene admin at 0.021 mg/dose without benzo(a)perylene. /From table/
... In this study, human hepatoma HepG2 cells cotreated with benzo[a]pyrene (BaP) and benzo[g,h,i]perylene (BghiP) were used as a model to investigate the cocarcinogenic mechanism of BghiP in BaP-induced carcinogenesis. DNA adduct formation is thought to initiate carcinogenesis, so the effect of BghiP on BaP-DNA adduct formation was evaluated using a (32)P-postlabeling assay. The BaP-DNA adduct levels increased following the addition of BghiP, in a dose-dependent manner. However, no adducts were formed with BghiP alone. /A/ previous report showed that cytochrome P450 1A1 (CYP1A1) is responsible for the metabolic activation of BaP and the formation of B[a]P adduct in HepG2 cells. Western blot and Northern blot analyses were used to evaluate whether BaP-induced CYP1A1 protein and mRNA levels increased following the addition of BghiP. Our data showed that BghiP enhanced BaP-induced CYP1A1 protein and its mRNA levels. To understand whether BghiP enhances BaP-induced CYP1A1 gene expression through the aryl hydrocarbon receptor (AhR) signaling pathway, a gel retardation assay was performed to elucidate the synergistic mechanism of BghiP in BaP-induced CYP1A1 gene expression. The results showed that BghiP causes an increase in the nuclear accumulation of AhR in cells and/or activation of AhR to a DNA-binding form. There was a concordant increase in the transcription activation of CYP1A1 gene and the induction of AhR signal pathway. Our findings demonstrated that BghiP enhances BaP-induced CYP1A1 transcription by AhR activation and suggested that the induction mechanism of CYP1A1 contributes to the cocarcinogenic potential of BghiP in BaP-induced carcinogenesis.
12-O-Tetradecanoylphorbol 13-acetate (TPA), a known tumor promoter, enhances the morphologic transformation of Syrian hamster embryo cells induced by low transforming concentrations of N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) (0.025-0.1 ug/mL) without potentiation of cell lethality or of changes in sister chromatid exchanges (SCEs) or chromosomal aberration frequencies. When MNNG was added to logarithmically growing cultures and TPA was added 2, 24, or 48 hr later, no changes in SCE frequency relative to MNNG alone occurred. Similar results were obtained with TPA in cells that had been exposed to MNNG in stationary growth phase. Whereas no transformation occurred with TPA alone and pretreatment with TPA did not affect MNNG transformation, its addition 2 hr after MNNG reduced transformation frequency but addition 24-72 hr after MNNG increased the transformation frequency up to 6-fold. TPA had a minimal effect on increasing the transformation frequency (2-fold) induced by MNNG at 0.25 ug/mL, a high concentration. Of three polycyclic hydrocarbons, perylene, benzo[g,h,i]perylene, and benz[a]anthracene, known as weak or noncarcinogens, only benz[a]anthracene induced a very low transformation frequency; however, after TPA, transformation occurred with all three. Because the number of cells whose transformation was initiated by low doses of carcinogen is much larger than the number of cells giving rise to transformed colonies in the absence of TPA, the frequency of the initial event is greater than can be expected from point mutations. Furthermore, the promotional aspect of transformation is not accompanied by a parallel increase in SCE.
The genotoxicity of 15 polycyclic aromatic hydrocarbons was determined with the alkaline version of the comet assay employing V79 lung fibroblasts of the Chinese hamster as target cells. These cells lack the enzymes necessary to convert PAHs to DNA-binding metabolites. ... 11 PAHs, i.e., benzo[a]pyrene (BaP), benz[a]anthracene, 7,12-dimethylbenz[a]anthracene, 3-methylcholanthrene, fluoranthene, anthanthrene, 11H-benzo[b]fluorene, dibenz[a,h]anthracene, pyrene, benzo[ghi]perylene and benzo[e]pyrene caused DNA strand breaks even without external metabolic activation, while naphthalene, anthracene, phenanthrene and naphthacene were inactive. When the comet assay was performed in the dark or when yellow fluorescent lamps were used for illumination the DNA-damaging effect of the 11 PAHs disappeared. White fluorescent lamps exhibit emission maxima at 334.1, 365.0, 404.7, and 435.8 nm representing spectral lines of mercury. In the case of yellow fluorescent lamps these emissions were absent. Obviously, under standard laboratory illumination many PAHs are photo-activated, resulting in DNA-damaging species. This feature of PAHs should be taken into account when these compounds are employed for the initiation of skin cancer. ...

TERRESTRIAL FATE: Based on a classification scheme(1), measured Koc value of 6.3X10+6(2) and 4.1X10+4(3), indicate that benzo(ghi)perylene is expected to be immobile in soil(SRC). Volatilization of benzo(ghi)perylene from moist soil surfaces is not expected to be an important fate process(SRC) given a Henry's Law constant of 3.31X10-7 atm-cu m/mole(4). Benzo(ghi)perylene is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1X10-10 mm Hg at 25 °C(5). In general, PAHs with five or more benzene rings do not biodegrade readily(6). Biodegradation of PAHs having five or more rings, including benzo(ghi)perylene, was slight to non-existent in three soils under field conditions(7). Soil degradation studies have found that benzo(ghi)perylene degrades slowly with half-lives ranging from 173 to 863 days(8-10). Benzo(ghi)perylene absorbs strongly at wavelengths >290 nm(11) and, therefore, is expected to be susceptible to direct photolysis on soil surfaces exposed to sunlight(SRC).
AQUATIC FATE: Based on a classification scheme(1), measured Koc value of 6.3X10+6(2) and 4.1X10+4(3), indicates that benzo(ghi)perylene is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(4) based upon a Henry's Law constant of 3.31X10-7 atm-cu m/mole(5). According to a classification scheme(6), an estimated BCF of 11,000(SRC), from its log Kow of 6.63(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is very high(SRC), provided the compound is not metabolized by the organism(SRC). However, it may not bioconcentrate in aquatic organisms which contain microsomal oxidase, such as fish, as this enzyme enables the rapid metabolism of certain polycyclic aromatic hydrocarbons(9). A measured fish biotransformation half-life of 1.1 days has been reported for the analogous compound benzo(a)pyrene(10). In general, PAHs with five or more benzene rings do not biodegrade readily(11). Biodegradation of PAHs having five or more rings, including benzo(ghi)perylene, was slight to non-existent in three soils under field conditions(12). A laboratory study using acclimated water and sediment from the Yellow River found that water high in sediment content could biodegrade benzo(ghi)perylene(13).
ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), benzo(ghi)perylene, which has a vapor pressure of 1.0X10-10 mm Hg at 25 °C(2), is expected to exist primarily in the particulate phase in the ambient atmosphere. Based on an estimated super-cooled vapor pressure of 3.2X10-8 mm Hg at 25 °C(3), a small percentage of benzo(ghi)perylene is expected to exist in the vapor phase in the ambient atmosphere(1). Ambient monitoring studies have detected benzo(ghi)perylene in both the particulate and vapor phases(4,5). Vapor-phase benzo(ghi)perylene is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 4.4 hours(SRC), calculated from its rate constant of 8.7X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase benzo(ghi)perylene is also degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 4.5 hours(SRC), calculated from a measured rate constant of 8.5X10-11 cu cm/molecule-sec at 25 °C(6). Particulate-phase benzo(ghi)perylene may be removed from the air by wet and dry deposition(SRC). Benzo(ghi)perylene absorbs strongly at wavelengths >290 nm(7) and, therefore, is expected to be susceptible to direct photolysis by sunlight(SRC).
Fruits and vegetables collected from 19 localities in southern Moravia (Czech Republic) in 2003 were found in contain the following concentrations of benzo(ghi)perylene (in ug/kg fresh weight): parsely (0.02-0.05), tomato (0.02-0.06), apple (0.02-0.08), apricot (0.03-0.46), cauliflower (0.01-0.21), grape (0.04-0.09), cabbage (0.02)(1). Benzo(ghi)perylene has been detected in food samples at levels >1.0 ug/kg in many food categories including fats and oils, vegetable oils, processed fruit, dried fruit, vegetables, cocoa, whole grains, flour, meat, molluscs, fish, herbs, spices, coffee and tea(2).
Nineteen of 23 samples of margarines, butter and vegetable oils contained benzo(ghi)perylene at concentrations ranging from 0.02 to 2.4 ug/kg with an avg of 0.59 ug/kg(1). Composite fish samples from the Great Lakes harbors and tributary mouths contained benzo(ghi)perylene(2). Smoked fish including dried herring, whitefish and Kippered cod showed benzo(ghi)perylene at concentrations of 1.0, 2.4 and 2.2 ppb, respectively(3). Japanese horse mackerel contained benzo(ghi)perylene for 3 different methods of preparation at concentrations of 2-10, 2 and 1 ppb(3). Broiled steaks, smoked ham and barbecued ribs and beef contained benzo(ghi)perylene at concentrations of 6.7, 1.2, 4.7 and 4.3 ppb, respectively(3). Smoked sausage and cooked bologna contained benzo(ghi)perylene at concentrations raging from 0.25 to 0.50 and 0.04 to 0.20 ppb, respectively(3). Coffee soots contained benzo(ghi)perylene at concentrations ranging from 100 to 140 ppb(3). Smoked cod liver oil, halibut liver oil and coconut oil each contained benzo(ghi)perylene at a concentration of 20 ppb(3). The minimum and maximum benzo(ghi)perylene concentration in lettuce grown 8, 15, 25, 35, 45 and 65 m from a major highway were 1.7, 2.7; 1.1, 1.6; 0.9, 1.3; 0.9, 1.3; 0.8, 1.3; and 0.7, 1.0; ug/kg, respectively(4). The concentration of benzo(ghi)perylene in the peel, inner peel, outer core, and core of carrot tissues was determined to be 4.5 ug/kg dry weight, below detection, 4.8 ug/kg dry weight, and below detection, respectively(5). The fine aerosol emission rate for benzo(ghi)perylene from a charbroiled hamburger (regular) was determined to be 0.24 mg/kg(6).
The substance can be absorbed into the body by inhalation of its aerosol and through the skin.

In an analysis of 21 human milk samples collected from non-smoking women in Beijing, China during 2005-2006, benzo(ghi)perylene was detected at mean, median, minimum and maximum concentrations of 0.030, 0.019, not detectable and 0.135 ng/g fresh weight respectively(1).
IDENTIFICATION AND USE: Benzo(ghi)perylene (BghiP) is a solid. It is used in small amounts for scientific research. Polycyclic aromatic hydrocarbons (PAHs) are a group of chemicals that are formed during the incomplete burning of coal, oil, gas, wood, garbage, or other organic substances, such as tobacco and charbroiled meat. HUMAN EXPOSURE AND TOXICITY: In human cells BghiP can activate the overexpression of aryl hydrocarbon receptor (AhR) and cytochrome CYP4B1, and the effects are abated by the AhR receptor antagonist. BghiP represents the group of PAHs lacking a "classic" bay region and hence it cannot be metabolically converted to bay region dihydrodiol epoxides considered as ultimate mutagenic and carcinogenic metabolites of PAH. Experimental results demonstrate lower human genotoxicity profile of B[ghi]P than for benzo[a]pyrene. ANIMAL STUDIES: Benzo(ghi)perylene showed no tumorigenic effect in the respiratory tracts of rats when given at doses of 5 mg. BghiP was analyzed for induction effect on skin and liver aryl hydrocarbon hydroxylase and 7-ethoxycoumarin o-deethylase activities in neonatal rats. A single topical application caused induction of liver enzymes without producing effects on skin enzymes. BghiP exhibits bacterial mutagenicity in strains TA98 and TA100 of Salmonella typhimurium after metabolic activation. ECOTOXICITY STUDIES: BghiP was responsible for retardation of growth and increases in adrenal and nasal gland weight in nestling herring gulls (Larus argentatus).
The ability of PAH's to bind to blood proteins such as albumin allows them to be transported throughout the body. Many PAH's induce the expression of cytochrome P450 enzymes, especially CYP1A1, CYP1A2, and CYP1B1, by binding to the aryl hydrocarbon receptor or glycine N-methyltransferase protein. These enzymes metabolize PAH's into their toxic intermediates. The reactive metabolites of PAHs (epoxide intermediates, dihydrodiols, phenols, quinones, and their various combinations) covalently bind to DNA and other cellular macromolecules, initiating mutagenesis and carcinogenesis.

Based upon the average atmospheric concentration of benzo(ghi)perylene at a remote site of 0.25 ng/cu m(1) and the average daily inhalation for a human adult of 20 cu m of air, the average daily intake of benzo(ghi)perylene via air is 20 pg(SRC). Based upon the average concentration of benzo(ghi)perylene among various food groups of 1 ng/kg(2,3) and the average daily consumption for a human adult of 1600 g of food, the average daily intake of benzo(ghi)perylene via food is 1.6 ug(SRC).
/BIRDS and MAMMALS/ The physiological effects of a single ingested dose of Prudhoe Bay Crude Oil (PBC), its aromatic fractions, and PBC Corexit 9527 emulsion were studied in nestling herring gulls (Larus argentatus). The high molecular weight aromatic compounds, including benzo(ghi)perylene, were responsible for retardation of growth and increases in adrenal and nasal gland weight.

Toxic pollutant designated pursuant to section 307(a)(1) of the Federal Water Pollution Control Act and is subject to effluent limitations. /Polynuclear aromatic hydrocarbons (including benzanthracenes, benzopyrenes, benzofluoranthene, chrysenes, dibenz-anthracenes, and indenopyrenes)/
For the maximum protection of human health from the potential carcinogenic effects of exposure to polynuclear aromatic hydrocarbons through ingestion of contaminated water and contaminated aquatic organisms, the ambient water concentration should be zero, based on the nonthreshold assumption for this chemical. However, zero level may not be attainable at the present time. Therefore, the levels which may result in incremental increase of cancer risk over the lifetime are estimated at 1X10-5, 1X10-6, and 1X10-7. The corresponding recommended criteria are 28.0 ng/L, 2.8 ng/L, and 0.28 ng/L, respectively. If these estimates are made for consumption of aquatic organisms only, excluding consumption of water, the levels are 311.0 ng/L, 31.1 ng/L, and 3.11 ng/L, respectively. /Polynuclear aromatic hydrocarbons/.
After incubation with liver microsomes from nonpretreated rats, no metabolites were found from benzo(ghi)perylene.
The genotoxicity of 15 polycyclic aromatic hydrocarbons was determined with the alkaline version of the comet assay employing V79 lung fibroblasts of the Chinese hamster as target cells. These cells lack the enzymes necessary to convert PAHs to DNA-binding metabolites. ... 11 PAHs, i.e., benzo[a]pyrene (BaP), benz[a]anthracene, 7,12-dimethylbenz[a]anthracene, 3-methylcholanthrene, fluoranthene, anthanthrene, 11H-benzo[b]fluorene, dibenz[a,h]anthracene, pyrene, benzo[ghi]perylene and benzo[e]pyrene caused DNA strand breaks even without external metabolic activation, while naphthalene, anthracene, phenanthrene and naphthacene were inactive. When the comet assay was performed in the dark or when yellow fluorescent lamps were used for illumination the DNA-damaging effect of the 11 PAHs disappeared. White fluorescent lamps exhibit emission maxima at 334.1, 365.0, 404.7, and 435.8 nm representing spectral lines of mercury. In the case of yellow fluorescent lamps these emissions were absent. Obviously, under standard laboratory illumination many PAHs are photo-activated, resulting in DNA-damaging species. This feature of PAHs should be taken into account when these compounds are employed for the initiation of skin cancer. ...
PAH metabolism occurs in all tissues, usually by cytochrome P-450 and its associated enzymes. PAHs are metabolized into reactive intermediates, which include epoxide intermediates, dihydrodiols, phenols, quinones, and their various combinations. The phenols, quinones, and dihydrodiols can all be conjugated to glucuronides and sulfate esters; the quinones also form glutathione conjugates. (L10)
An analytical procedure is described which includes extraction of polycyclic aromatic hydrocarbons (PAH), including benzo(ghi)perylene, and polycyclic aromatic hydrocarbons metabolites from urine, reduction of metabolites to the original polycyclic aromatic hydrocarbons and subsequent analysis by HPLC. The mean value of the sum of the 11 polycyclic aromatic hydrocarbons in non smoker's urine was 1.1 ug/mmol creatinine. The sum of polycyclic aromatic hydrocarbons in smoker's urine was significantly higher. Increased levels of PAH were found in the urine of aluminum reduction workers.
... Benzo(ghi)perylene is absorbed readily from the gastrointestinal tract and lung. In general, polycyclic aromatic hydrocarbons are highly lipid soluble and can pass across epithelial membranes.
Used for scientific research; Not commercially used or produced; [HSDB] Benzo(ghi)perylene is present as a component of polycyclic aromatic hydrocarbons (PAH) content in the environment usually resulting from the incomplete combustion or pyrolysis of organic matters, especially fossil fuels and tobacco.

PAHs are generally not produced commercially in the United States except as research chemicals. /Polycyclic aromatic hydrocarbons/
PAHs are released into the environment via the combustion of fossil fuels, coke oven emissions and vehicle exhausts, as well as naturally from forest fires and vocanic eruptions. PAHs from these sources may contaminate nearly water systems. They are also found in coal tar and charbroiled food. (L10)
Benzo(ghi)perylene occurs ubiquitously in products of incomplete combustion; it also occurs in considerable amounts in coal-tar and is an important component of gasoline engine exhaust.
PAHs are a group of chemicals that are formed during the incomplete burning of coal, oil, gas, wood, garbage, or other organic substances, such as tobacco and charbroiled meat. There are more than 100 different PAHs. PAHs generally occur as complex mixtures (for example, as part of combustion products such as soot), not as single compounds. PAHs usually occur naturally, but they can be manufactured as individual compounds for research purposes; however, not as the mixtures found in combustion products. ... Others are contained in asphalt used in road construction. They can also be found in substances such as crude oil, coal, coal tar pitch, creosote, and roofing tar. They are found throughout the environment in the air, water, and soil. They can occur in the air, either attached to dust particles or as solids in soil or sediment. /Polycyclic aromatic hydrocarbons/
