Polynuclear Aromatic Hydrocarbons (PAHs)

Explore a targeted panel of parent and substituted PAHs through an interactive structural-family map organized by aromatic ring count and related chemical classes.

18 PAH analytes

This map emphasizes structural and chemical-family relationships rather than metabolic pathway flux. Ring count, alkyl substitution, and molecular complexity provide the main organizing framework.

PAH analytes and structural-family relationships

Select a measured PAH to view its chemical context. Use View Pathway Graphic to explore how the panel spans low- through high-molecular-weight PAHs.

Interpretive noteThis page organizes the assay by chemical structure rather than by a biological pathway. Relationships shown in the graphic represent shared ring systems, substitution patterns, and increasing molecular complexity across the PAH panel.

The structural map highlights related parent compounds, alkylated analogs, and increasing ring count from lower- to higher-molecular-weight PAHs. Select a compound in either view to jump to its context below.
