Oxygen-, nitrogen, and sulfur-containing PAHs were measured in stream sediments.

Urban sediments have 2.4 times greater concentrations than rural sediments.

Substituted PAHs were highly correlated with PAHs, indicating a common source.

Impervious surface, road miles, and residential land were also highly correlated.

Substituted PAH measurements may help refine urban PAH sources.
