Abstract In the aquatic environment, ubiquitous natural factors such as ultraviolet light (UV) and dissolved organic carbon (DOC) are likely to influence crude oil toxicity. The present study examined the interactive effects of DOC, UV, and DOC–UV co‐exposure on the acute toxicity of Deepwater Horizon crude oil in larval red drum ( Sciaenops ocellatus ). Although DOC alone did not influence crude oil toxicity, it mildly reduced UV photo‐enhanced toxicity. Environ Toxicol Chem 2020;39:2509–2515. © 2020 SETAC
