Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- Data are particularly plentiful for fish and one semi-field study with freshwater organisms is also available. Regarding acute toxicity data for freshwater organisms, fish are the most sensitive taxon to acute exposure with the lowest valid acute LC50 value available being 0.068 mg NH3/L for Oncorhynchus gorbuscha (pink salmon) alevins exposed to ammonia for a 96-hour period
