Description of key information
Acute fish toxicity was determind with Leudicsus idus in a screening approach (non GLP, no data on method) with 10 fish exposed to 2, 5 and 10 mg/L. No adverse effects or dead fish were observed at 2 mg/L. Derived from the result with 5 mg/L and 4 fish with adverse symptoms and 6 dead fish after 26 hours it was assumed that the LC 50 is to be expected in the range of 1-10 mg/L.
Key value for chemical safety assessment
Additional information
Although the study is rated as invalid it might be useful to derive the effect range of the substance which is expected to be 1 -10 mg/L.
