Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1972
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: no glp, no guideline a available (older than guideline and glp)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test)
- Deviations:
- not applicable
- Principles of method if other than guideline:
- For acute tests, 10 daphnids 12 +/- 12 hr old were placed in dublicate test chambers and subjected to the test condidions. Tests were run both with and without food additions as the food changed the values. Complete immobilisation or death was the endpoint. Time: 48h
- GLP compliance:
- no
- Analytical monitoring:
- yes
- Vehicle:
- no
- Test organisms (species):
- Daphnia magna
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- no
- Total exposure duration:
- 48 h
- Duration:
- 48 h
- Dose descriptor:
- LC50
- Effect conc.:
- 55 mg/L
- Nominal / measured:
- meas. (initial)
- Conc. based on:
- dissolved
- Basis for effect:
- mobility
- Remarks on result:
- other: value for Sn^{2+}
- Validity criteria fulfilled:
- yes
- Conclusions:
- LD50(daphnia, 48h)=55mg Sn / L = 99.5 mg SnSO_4 / L
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 1996
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: no glp, no methode, citated by RIVM
- Justification for type of information:
- Justification for read across: stannous sulphate and stannous chloride are the salts from strong acids (here: hydrochloric and sulfuric acid) wiith Sn(II). In water there is a complete dissoziation in the Sn(II) and the corresponding acid.
In the study water phase the concentration of chloride and sulfate from natural sources is dimension granter than from the test item. So the chloride and the sulfate is insignifican. For adverse effects only the Sn(II) is responsible - Qualifier:
- no guideline available

biota from the Egyptian coastal waters. J Environ Sci Health A31: 1529-1545. - GLP compliance:
- not specified
- Analytical monitoring:
- yes
- Test organisms (species):
- Idotea balthica basteri
- Test type:
- static
- Water media type:
- saltwater
- Total exposure duration:
- 106 h
- Duration:
- 106 h
