Description of key information

Three acute toxicity studies are available for MCS-1562 and include a freshwater fish, an invertebrate and an algae. A 96 -hr LC50 value of 2.9 mg/L was reported for rainbow trout (Oncorhynchus mykiss) based on mean measured test concentrations. In an acute test with Daphnia magna, the determined endpoint also based on geometric mean concentrations was a 48 -hr EC50 of 6.5 mg/L. Exposure to the green alga, Pseudokircherniella subcapitata resulted in a 72 -hr EC50 for growth rate inhibition of 2.6 mg/L, also based on geometric mean measured concentrations.
