- Adequacy of study:
- key study
- Study period:
- 13 - 14 Jul 1983
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test)
- Version / remarks:
- 1981
- Deviations:
- yes
- Remarks:
- compared to the newer versions of the guideline, only 24 h were tested in the version of 1981
- GLP compliance:
- not specified
- Analytical monitoring:
- yes
- Details on sampling:
- Samples for analysis were taken at 0 h and 24 h exposure
- Vehicle:
- no
- Details on test solutions:
- 1000 mg of the test item were dissolved in water and made up to 1000 mL.
Calculated amounts of stock solution to produce the desired test concentrations were given into the water and homogeneously distributed. - Test organisms (species):
- Daphnia magna
- Details on test organisms:
- Breeding: parthenogenetic reproduction
Feeding: with a suspension of green algae and yeast
Collection: 24 hours before the start of the test reproductive daphnia are separated from the young by sieving through a 800 µm sieve.This operation is repeated immediately before the start and the young daphnia (0 - 24h old) are retained for the test. - Test type:
- static
- Water media type:
- freshwater
- Limit test:
- no
- Total exposure duration:
- 24 h
- Test temperature:
- 19 - 22°C
- pH:
- 7.6 - 7.9
- Dissolved oxygen:
- 8.0 - 8.5 mg/L
- Nominal and measured concentrations:
- 0 (control), 100, 180, 320, 580, 1000 mg/L nominal
0 (control) , 91, 162, 299, 549, 965 mg/L measured (24 h) - Details on test conditions:
- TEST SYSTEM
- Test vessel: tubes
- Material, size, headspace, fill volume: plastic, 20 mL volume (10 mL fill volume), closed with steel cap
- No. of organisms per vessel: 5

EFFECT PARAMETERS MEASURED (with observation intervals if applicable) : mobility at 0 and 24 h - Reference substance (positive control):
- no
- Key result
- Duration:
- 24 h
- Dose descriptor:
- EC50
- Effect conc.:
- > 1 000 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
