Effects of natural organic matter/dissolved organic carbon on crude oil toxicity and bioaccumulation of polycyclic aromatic hydrocarbons

In this study, Red drum larvae (Sciaenops ocellatus) 24 hours post-fertilization were exposed for 48 hours to water accommodated fractions (WAFs) made with artificial seawater only or artificial seawater mixed natural dissolved organic matter. During the UV test, 8 consecutive hours of artificial UV-A radiation was delivered to test chambers during each day (16 h total), and integrated UV dose and UV intensity were measured during the exposure time. This dataset includes measurements of potential mitigating or enhancing effects of natural organic matter (NOM)/dissolved organic carbon (DOC) on crude oil and polycyclic aromatic hydrocarbon (PAH) toxicity and bioavailability.
