The LC50-value was determined graphically. - Validity criteria fulfilled:
- not specified
- Conclusions:
- The LC50 (48 hours) for fish (Leuciscus idus melanotus) was determined as 174 mg/L indicating that the test substance does not pose a significant
hazard to fish. - Executive summary:
The acute toxicity of the test item on Leuciscus idus melanotus was evaluated in a static fish test over a period of 48 hours (Hüls AG 1996). The test was conducted according to national guideline DIN 38412, part 15. The following endpoint was derived:
LC50 (48 hours): 174 mg/L
The study was assessed as "reliable with restrictions".
