Description of key information

Additional information

Short-term aquatic toxicity data are available for each of the three freshwater trophic levels (fish, daphnia and algae). The observed L(E)C₅₀ values were:

96-hour LC₅₀ for freshwater rainbow trout (Oncorhynchus mykiss) = 4.2 mg/L

48-hour EC₅₀ for freshwater invertebrate (Daphnia magna) = 52 mg/L

72-hour growth rate EC₅₀ (ECr₅₀) for freshwater algae (Pseudokirchneriella subcapitata) = 36 mg/L

Studies on long term testing on aquatic invertebrates and long-term testing on fish have been waived as the chemical safety assessment demonstrates safe use of ethyl 2,3-epoxy-3-phenylbutyrate and indicates no need to investigate further the effects on aquatic organisms.
