Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
A LC50 of 0.35 mg/L was determined when Danio rerio was exposed to (Z)-2-(8-Heptadecenyl)-4,5-dihydro-1H-imidazole-1-ethanol for 96 hours.
Executive summary:

An acute acute fish toxicity test according to OECD Guideline 203 was carried out with (Z)-2-(8-Heptadecenyl)-4,5-dihydro-1H-imidazole-1-ethanol in zebra fish (danio rerio). A LC50 of 0.35 mg/L was determined.
