PAHs are significant in the field of toxicology due to their potential carcinogenic and mutagenic properties. Some PAHs are classified as carcinogens by agencies such as the International Agency for Research on Cancer (IARC). Prolonged exposure to high levels of PAHs can lead to adverse health effects including cancer, respiratory issues, and immune system impairment. Understanding PAHs' toxicological profiles is crucial for assessing their risk to human health and the environment.
