Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 910-404-7 | CAS number: -
Long-term toxicity to aquatic invertebrates
Administrative data
- Endpoint:
- long-term toxicity to aquatic invertebrates
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Reliability:
- 3 (not reliable)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Total number of animals in the control treatment as well as in the exposure treatments at the start of testing was not reported, hence evaluation of the raw data (# surviving animals per treatment) was not possible. The ‘maximum safe level’ reported by the authors (here given as NOEC) is questionable and not based on statistical comparison of observed mortality/weight reduction.
