Oxygenated polycyclic aromatic hydrocarbons (OPAH) concentrations (ng/mL) and percentage of change in concentrations (% Δ) for standard test mixtures, Superfund, and Gulf of Mexico passive sampling device extracts before (C₀) and after (C₃₀) 30 min of ultraviolet B exposure

^aSamples collected from the Willamette River at river miles 7 west (w) and 6.5w; 7w represents the average of PSD field duplicates [27].

^bSamples collected from Grand Isle, Louisiana, USA, and Gulf Breeze, Florida, USA, coastal waters during and after the Deepwater Horizon oil spill [29].

^c% Δ = 100 × [(C₃₀/C₀) − 1]; percentage change, where C₀ = negative control in PP PAH standards exposures and non-UV-exposed extracts for PSD exposures.

PP PAH = US Environmental Protection Agency priority pollutant polyaromatic hydrocarbon; RM = river mile; 9-FLUO = 9-fluorenone; 9,10-ANTQ = 9,10-anthraquinone; CPdefPHEO = 4H-cyclopenta[def]phenanthrene-4-one; BaFLUO = benzo[a]-11-fluorenone; AANEQ = aceanthrenequinone; BaANCQ = benz[a]anthracenequinone; 5,12-NAPQ = 5,12-napthacenequinone. NC = change was less than 10% between C₀ and C₃₀; ND = not detected in C₀ or C₃₀.
