Abstract The toxicity of the oil dispersing agent Corexit® 7664 was evaluated using the early life stages of four California marine species: the red abalone (Haliotis rufescens), the topsmelt (Atherinops affinis), a mysid (Holmesimysis costata), and the giant kelp (Macrocystis pyrifera). Spiked-exposure, continuous-flow toxicity tests of 48–96 h were performed in triplicate in closed test chambers. Dispersant concentrations were measured by UV spectrophotometry. In terms of median-effect concentration, the order of test sensitivity was Haliotis〉Atherinops〉Holmesimysis〉Macrocystis. NOEC data also showed Haliotis tests to be the most sensitive, with Macrocystis tests having similar values, followed by Atherinops and Holmesimysis tests, respectively. Toxicity of Corexit® 7664 was compared to that of Corexit® 9527, and the latter was found to be more toxic to all four species; interspecific rankings were similar for the two agents.
