Toxicity to aquatic plants other than algae
Administrative data
Link to relevant study record(s)
- Endpoint:
- toxicity to aquatic plants other than algae
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Justification for type of information:
- It is accepted that the parent substance will have hydrolysed in the course of the testing, but OECD Guidance Document on Aquatic Toxicity Testing of Difficult Substances and Mixtures (Guideline 23) was followed.
The method allows for pre-mixing hydrolytically unstable substances in water to mimic the release to the environment via waste-water systems.
Analysis for parent material not possible. - Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 221 (Lemna sp. Growth Inhibition Test)
- Deviations:
- not specified
- GLP compliance:
- not specified
- Analytical monitoring:
- not specified
- Vehicle:
- not specified
- Test organisms (species):
- Lemna minor
- Test type:
- not specified
- Water media type:
- freshwater
- Total exposure duration:
- 14 d
- Duration:
- 14 d
- Dose descriptor:
- EC50
- Effect conc.:
- > 10 - < 20 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- frond number
- Duration:
- 14 d
- Dose descriptor:
- EC90
- Effect conc.:
- > 10 - < 20 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- growth rate
- Executive summary:
It is accepted that the parent substance will have hydrolysed in the course of the testing, but OECD Guidance Document on Aquatic Toxicity Testing of Difficult Substances and Mixtures (Guideline 23) was followed.
The method allows for pre-mixing hydrolytically unstable substances in water to mimic the release to the environment via waste-water systems.
Analysis for parent material not possible.

at 10 mg/dm3was reduction approx 60% in root length and reduction approx. 30% in leaf number,
at concentration of 20 mg/dm3reduction of root length and leaf number increased to 85% and 75% reduction of leaf numberDescription of key information
