Administrative data
Link to relevant study record(s)
- Endpoint:
- short-term toxicity to fish
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- February 1992
- Reliability:
- 2 (reliable with restrictions)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 203 (Fish, Acute Toxicity Test)
- GLP compliance:
- yes (incl. QA statement)
- Analytical monitoring:
- no
- Details on test solutions:
- Direct dispersion in water.Test material was dispersed in dechlorinated tap water and the volume adjusted to 1 litre to a give a 4.0 g/l stock solution. Two 500 ml aliquots of this stock solution were each dispersed in dechlorinated tap water and the volume adjusted to 20 litres to give two replicate test concentrations of 100 mg/l.
The test material was known to adsorb to glassware and so saturation of the adsorption sites was achieved by soaking the test vessels overnight prior to the start of the test with the test solutions. At 0 hours the test vessels were emptied, rinsed with the solution to be tested and then refilled with the fresh test solution.
Test media were renewed daily. - Test organisms (species):
- Oncorhynchus mykiss (previous name: Salmo gairdneri)
- Details on test organisms:
- Source: Parkwood Trout Farm, Wigmore, Kent, U.K.
Stock held since 14 January 1992 and acclimatised to test conditions from 27 January 1992 - 3 February 1992.
The stock fish were maintained in a glass fibre tank with a "single pass" water renewal system.
The lighting was controlled to give a 16 hours light and 8 hours darkness cycle.
Feeding: Commercial trout pellets daily. Discontinued 24h prior to test.
Mean standard length= 4.5 cm (SO = 0.3 cm).
Mean weight= 0.76 g (SO = 0.11 g). - Test type:

- Total exposure duration:
- 96 h
- Test temperature:
- 14°C
- pH:
- 7.4 - 9.4
- Dissolved oxygen:
- 10.0 -10.1 mg/L
- Nominal and measured concentrations:
