Executive summary:

A study was conducted to determine the acute toxicity of the test substance against Leuciscus idus using a method similar to DIN 0038412, Part L.15. No analytical dose verification was conducted. Under the study conditions, the nominal 96 h LC50 was established at 237 mg/L and the highest verified concentration without mortality was found to be 215 mg/L (Munk, 1979).
