Administrative data
Link to relevant study record(s)
- Endpoint:
- long-term toxicity to aquatic invertebrates
- 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:
- Data is from handbook and secondary source
- Qualifier:
- according to guideline
- Guideline:
- other: OECD 202 Daphnia Reproduction Test
- GLP compliance:
- not specified
- Analytical monitoring:
- not specified
- Vehicle:
- not specified
- Test organisms (species):
- Daphnia magna
- Test type:
- semi-static
- Water media type:
- freshwater
- Total exposure duration:
- 21 d
- Reference substance (positive control):
- not specified
- Duration:
- 21 d
- Dose descriptor:
- NOEC
- Effect conc.:
- 0.9 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- reproduction
- Duration:
- 21 d
- Dose descriptor:
- LOEC
- Effect conc.:
- 3.6 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- reproduction
- Validity criteria fulfilled:
- not specified
- Conclusions:
- The no observed effected concentration (NOEC) and low observed effect concentration (LOEC) was observed to be 0.9 mg/l and 3.6 mg/l respectively
- Executive summary:
An experiment was conducted to determine the Long term toxicity of test chemical to aquatic invertebrates according toOECD 202 Daphnia Reproduction Test. The test organism used in this study was Daphnia magna. The experiment was conducted in semi-static condition using fresh water. The test chemical was exposed to Daphnia Magna for 21 days. The no observed effected concentration (NOEC) and low observed effect concentration (LOEC) was observed to be 0.9 mg/l and 3.6 mg/l respectively. By considering the LOEC value test chemical is considered to be non toxic to aquatic invertebrates and cannot be classified as per CLP regulation
