creosotové

Creosotové, often referred to as creosote oil, is a complex mixture of chemicals produced during the high-temperature distillation of coal tar or wood. The composition of creosote varies depending on the source material, but it typically contains a wide range of aromatic hydrocarbons, including phenols, cresols, and polycyclic aromatic hydrocarbons (PAHs). Historically, creosote has been widely used as a wood preservative due to its excellent insecticidal and fungicidal properties. This application made it a common treatment for railroad ties, utility poles, and marine pilings, significantly extending their service life by protecting them from decay and insect infestation.

However, concerns regarding the environmental and health impacts of creosote have led to restrictions on its use in many regions. The chemicals present in creosote, particularly PAHs, are known to be persistent in the environment and can pose risks to ecosystems and human health. Exposure can occur through direct contact, inhalation, or ingestion, and some components are classified as probable carcinogens. Consequently, its use is now more regulated, and alternative wood preservatives have gained prominence. Despite these limitations, creosote continues to be employed in specific industrial applications where its effectiveness is deemed essential and proper handling and disposal procedures are strictly followed.
