Passive sampling coupled to UV irradiation: A useful analytical approach for studying oxygenated polycyclic aromatic hydrocarbon formation in bioavailable mixtures

0
We investigated coupling passive sampling technologies with ultraviolet irradiation experiments to study polycyclic aromatic hydrocarbon (PAH) and oxygenated PAH (OPAH) transformation processes in real‐world bioavailable mixtures. Passive sampling device (PSD) extracts were obtained from coastal waters impacted by the Deepwater Horizon oil spill and Superfund sites in Portland, OR. OPAHs were found in the contaminated waters with our PSDs. All mixtures were subsequently exposed to a mild dose of UVB. A reduction in PAH levels and simultaneous formation of several OPAHs were measured. Site specific differences were observed with UVB exposed PSD mixtures. Environ Toxicol Chem © 2013 SETAC
