In the aquatic environment, ubiquitous natural factors such as ultraviolet light (UV) and dissolved organic carbon (DOC) are likely to influence crude oil toxicity. This study examined the interactive effects of DOC, UV and DOC-UV co-exposure on the acute toxicity of Deepwater Horizon crude oil on larval red drum (Sciaenops ocellatus). While DOC alone did not influence crude oil toxicity, it mildly reduced UV photo-enhanced toxicity. This article is protected by copyright. All rights reserved.
