Used primarily in research and environmental studies, this chemical serves as a marker for identifying and assessing pollution levels, particularly in air and water. It is often analyzed in environmental samples to monitor the presence of polycyclic aromatic hydrocarbons (PAHs), which are indicative of combustion processes and industrial emissions. Additionally, it plays a role in toxicological studies to understand the effects of long-term exposure to PAHs on human health and ecosystems. Its detection helps in formulating regulations and strategies to mitigate environmental contamination and protect public health.
