Creosote is a thick, dark liquid that is produced from the distillation of coal tar or wood tar. It is primarily composed of polycyclic aromatic hydrocarbons (PAHs) and phenolic compounds. Creosote is commonly used as a wood preservative to protect against rot, insects, and fungal decay. It has been historically used in railway ties and utility poles. In some contexts, particularly in environmental discussions, creosote is noted for its potential health hazards and environmental impact, as it can be toxic and carcinogenic.
