The main chemical extracted on the commercial scale from the higher-boiling oils (b.p. 250°C, 480°F) is crude anthracene. The majority of the crude anthracene is used in the manufacture of dyes after purification and oxidation to anthraquinone.

Benz[a]anthracene has been shown to be carcinogenic to experimental animals. 1,2-Benzanthracene has been listed and grouped as an A2, meaning a suspected human carcinogen by the ACGIH and the NTP, and the IARC classified it as Group 2A, meaning a probable human carcinogen.

Anthracene is a polycyclic aromatic hydrocarbon (PAH) containing three melted benzene rings that are obtained during the final stage of the distillation of coal tar. Anthracene is similar to a solid crystal; it is colorless or pale yellow and is mainly used as a luminescent and in insecticides, fungicides and gasoline coagulants. Anthracene is representative of PAH contaminants and has been used in the present study to analyze PAH-contaminated soil. PAHs are persistent organic compounds that are abundant in the environment. They consist of two or more melted benzene rings, with low volatility, low solubility in water, and low biodegradation (Lamichhane, Bal Krishna, and Sarukkalige 2017). This leads to an increase in the annual accumulation of PAHs in the soil and groundwater environments; thus, their emissions cannot be ignored.

Anthracene is a solid polycyclic aromatic hydrocarbon (PAH, C14H10) consisting of three fused benzene rings (ATSDR, 1990). PAHs are persistent organic pollutants that are resistant to biodegradation and can remain in the environment for a long period of time (Maliszewska-Kordybach 1999). Anthracene is a colourless or pale-yellow quasicrystal solid found in coal tar. It is mainly used for the production of dyes and pesticides, for wood preservation, in metal coatings and the plastics industry, and in the production of fossil fuel by incomplete combustion. Anthracene has been designated a major environmental pollutant by the US Environmental Protection Agency and has been placed on the very high concern list of the European Chemicals Agency (Delgado and Romero 2013). Anthracene has polluted the soil and reduced its strength around pesticide production factories and plastic industries near the cities of Karaj and Tehran (Estabragh et al. 2018). The anthracene used in this study was obtained from Merck (Germany) and its physical properties are listed in Table 5.

Anthracene is a three fused benzene ring PAH, one among the 16 EPA Priority PAHs. It was chosen as a model compound for the study of PAH degradation due to its hydrophobicity, potential to bioaccumulate in the ecosystem, and severe relative toxicity.
