Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Read-across from an analogue substance for which a guideline study (Klimish 1) is available.
- Reason / purpose for cross-reference:
- read-across source
- Principles of method if other than guideline:
- Read-across approach from experimental data (study according to OECD 202 and GLP) on an analogue substance P0310.
- Key result
- Duration:
- 48 h
- Dose descriptor:
- NOEC
- Effect conc.:
- >= 124.5 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mobility
- Remarks on result:
- other: Based on a read-across from an analogue subtance.
- Details on results:
- Based on experimental results on analogue substance P0310 where 48h-NOEC was ≥ 100 mg/L (based on mobility), the read-across approach is applied and the 48h-NOEC for substance P-1057 is calculated to be ≥124.5 mg/L.
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- Based on read-across approach from analogue substance P0310, the NOEC (48h) of the substance P-1057 is calculated to be 124.5 mg/L.
- Executive summary:
Based on experimental results obtained in a study according to OECD 202 on analogue substance P0310 where 48h-NOEC for Daphnia magna was determined to be>100 mg/L (based on mobility), the read-across approach is applied and the 48h-NOEC for substance P-1057 is determined to be ≥124.5 mg/L.
