多环芳烃及其烷基同系物分布在世界各地的沉积物中。在大多数研究地点，多环芳烃的定性模式是明显不变的，而多环芳烃的定量丰度随着靠近城市中心而增加。这些发现与人为燃烧是这些化合物的主要来源相一致。多环芳烃的两种非燃烧来源也被注意到：来自枞酸的网烯和可能来自各种延伸醌色素的苝。
Polycyclic aromatic hydrocarbons (PAH) and their alkyl homologs are distributed in sediments throughout the world. The qualitative PAH pattern is remarkedly constant for most of the locations studied, and the quantitative PAH abundance increases with proximity to urban centers. These findings are consistent with anthropogenic combustion being the major source of these compounds. Two non-combustion sources of PAH were also noted: retene coming from abietic acid and perylene probably coming from various extended quinone pigments.
