If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.

Carcinogenicity

Based on no human data and sufficient data from animal assays, IRIS classifies dibenz [a,h]anthracene as a B2 carcinogen, a probable human carcinogen, and the IARC classifies dibenz[a,h]anthracene as a 2A carcinogen. Dibenz[a,h]anthracene produced carcinomas in mice following oral or dermal administration and injection site tumors in several species following s.c. or i.m. injection. It is also a tumor initiator.

Source

Constituent in coal tar, cigarette smoke (4 μg/1,000 cigarettes), and exhaust condensate of gasoline engine (96 μg/g) (quoted, Verschueren, 1983). Also detected in asphalt fumes at an average concentration of 12.25 ng/m³ (Wang et al., 2001).
Based on laboratory analysis of 7 coal tar samples, dibenz[a,h]anthracene was not detected (EPRI, 1990). Lehmann et al. (1984) reported dibenz[a,h]anthracene concentrations of 0.03 mg/g and 1,300 mg/kg in a commercial anthracene oil and high-temperature coal tar, respectively. Identified in a high-temperature coal tar pitch used in roofing operations at concentrations ranging from 317 TO 1,680 mg/kg (Malaiyandi et al., 1982).
Nine commercially available creosote samples contained dibenz[a,h]anthracene at concentrations ranging from 1 to 16 mg/kg (Kohler et al., 2000).
Under atmospheric conditions, a low rank coal (0.5–1 mm particle size) from Spain was burned in a fluidized bed reactor at seven different temperatures (50 °C increments) beginning at 650 °C. The combustion experiment was also conducted at different amounts of excess oxygen (5 to 40%) and different flow rates (700 to 1,100 L/h). At 20% excess oxygen and a flow rate of 860 L/h, the amount of dibenz[a,h]anthracene emitted ranged from 32.0 ng/kg at 900 °C to 260.9 ng/kg at 750 °C. The greatest amount of PAHs emitted were observed at 750 °C (Mastral et al., 1999).

Environmental Fate

Biological. In activated sludge, <0.1% of the applied dibenz[a,h]anthracene mineralized to carbon dioxide after 5 d (Freitag et al., 1985). Based on aerobic soil die away test data, the estimated half-lives ranged from 361 to 940 d (Coover and Sims, 1987).
Ye et al. (1996) investigated the ability of Sphingomonas paucimobilis strain U.S. EPA 505 (a soil bacterium capable of using fluoranthene as a sole source of carbon and energy) to degrade 4, 5, and 6-ringed aromatic hydrocarbons (10 ppm). After 16 h of incubation using a resting cell suspension, only 7.8% of dibenz[a,h]anthracene had degraded. It was suggested that degradation occurred via ring cleavage resulting in the formation of polar metabolites and carbon dioxide.
Soil. The reported half-lives for dibenz[a,h]anthracene in a Kidman sandy loam and McLaurin sandy loam are 361 and 420 d, respectively (Park et al., 1990).
Photolytic. A carbon dioxide yield of 45.3% was achieved when dibenz[a,h]anthracene adsorbed on silica gel was irradiated with light (λ >290 nm) for 17 h (Freitag et al., 1985). The photooxidation half-life in the atmosphere was estimated to range from 0.428 to 4.28 h (Atkinson, 1987).
Chemical/Physical. Dibenz[a,h]anthracene will not hydrolyze because it does not contain a hydrolyzable functional group (Kollig, 1993).
At influent concentrations of 1.0, 0.1, 0.01, and 0.001 mg/L, the GAC adsorption capacities were 69, 12, 2.1, and 0.39 mg/g, respectively (Dobbs and Cohen, 1980).

Purification Methods

The yellow-green colour (due to other pentacyclic impurities) is removed from it by crystallising from *benzene or by selective oxidation with lead tetraacetate in acetic acid [Moriconi et al. J Am Chem Soc 82 3441 1960]. [Beilstein 5 IV 2722.]

Toxicity evaluation

Dibenz[a,h]anthracene is largely associated with particulate matters, soils, and sediments. Its presence in places distant from primary sources indicates that it is reasonably stable in the atmosphere and capable of long-distance transport.
Dibenz[a,h]anthracene can be adsorbed very strongly if released to the soil. However, no leaching to the groundwater or hydrolization or evaporation from soils surface is expected.With half-lives of 18 and 21 days, it is generally subjected to biodegradation in soil systems. Volatilization of dibenz[a,h] anthracene from wet soil surfaces is not expected to be an important fate process based on an estimated Henry’s Law constant of 7.3×10^-8 atm-m3 mol^-1. A biodegradation halflife of 750 days at 20°C after incubation with unacclimated soil microcosms indicates that biodegradation is not an important environmental fate process in soil.
Dibenz[a,h]anthracene released to the atmosphere will likely be associated with particulate matter and may be subjected to moderately long-range transport, depending mainly on the particle size distribution and climatic conditions, which will determine the rates of wet and dry deposition. The estimated vapor pressure of 9.5×10¹⁰ mm Hg at 25°C of dibenz[a,h] anthracene indicates that this compound will exist solely in the particulate phase in the ambient atmosphere if released into air. Its presence in areas remote from primary sources demonstrates the potential for this long-range transport as well as dibenz[a,h]anthracene’s considerable stability in the air. Dibenz[a,h]anthracene absorbs solar radiation strongly, suggesting that it may be susceptible to direct photolysis in the environment. The estimated vapor phase half-life in the atmosphere is 1 day as a result of reaction with photochemically produced hydroxyl radicals.

Incompatibilities

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explo- sions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides.

Waste Disposal

See the entry on Coal Tar Pitch Volatiles. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/ mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
