Abstract The acute toxic response of species pairs tested simultaneously was determined for three toxicants; sodium lauryl sulfate, cadmium, and Lannate® (methomyl). One species in each test was that recommended by the U.S. Environmental Protection Agency (EPA), the other a closely related species. Species-pairs includedProrocentrum minimum — Pseudoisochrysis paradoxa-Skeletonema costatum (phytoplankters),Neomysis americana-Mysidopsis bahia (mysid shrimp),Eurytemora affinis-Acartia tonsa (copepod) andMenidia menidia-Cyprinodon variegatus (fish). For each toxicant, the species pairs yielded similar lethal (effective) concentrations for 50% of the test animals [LC (EC) 50s]. The LC (EC) 50s differed by no more than 4.7 with the exception of the phytoplankton response to cadmium, in which caseProrocentrum minimum was markedly more sensitive than the other phytoplankters. Mysids were most sensitive to cadmium and Lannate, and algae were most sensitive to sodium lauryl sulfate.
