Administrative data
Link to relevant study record(s)
- Endpoint:

- experimental study
- Adequacy of study:
- weight of evidence
- Study period:
- 28 days
- Reliability:
- 2 (reliable with restrictions)
- Justification for type of information:
- Taken from Australian Government review. Primary source data not found
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 215 (Fish, Juvenile Growth Test)

- Test type:
- flow-through
- Water media type:
- freshwater
- Duration:
- 28 d
- Dose descriptor:
- other: LC100
- Effect conc.:
- 1 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mortality
- Details on results:
- There was 100% mortality in the lowest test group
Under flow test condition concentrations are nominal, but the toxicant is continuously added to water stream to keep the actual concentrations
Reference
Description of key information
Long term toxicity work and studies on early life stage fish show similar variation between studies.
The most severe data is used for classification, suggesting long-term LC50 in range 0.01 - 0.1 mg/l, confirming Aquatic Chronic 2 (considering rapid biodegradation)
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Dose descriptor:
- LC10
- Remarks:
- Note that LC50 cited in data.
- Effect concentration:
- > 0.01 - < 0.1 mg/L
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
