asphalt

Asphalt is a dark liquid. It is also a mixture of heavy hydrocarbon residues including saturated and unsaturated hydrocarbons and aromatic hydrocarbons.

Anthracene is a polycyclic aromatic hydrocarbon (PAH) consisting of three fused benzene rings that presents as a colorless, solid, crystalline substance derived primarily from coal tar, known for its characteristic blue fluorescence under ultraviolet light and its extensive use as a fundamental raw material for producing anthraquinone dyes, synthetic fibers, and various other organic compounds. While Anthracene serves as a component in some wood preservatives and asphalt products, Anthracene is also a recognized environmental pollutant and is classified as a potential occupational carcinogen by some regulatory bodies.
