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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Toxicity to aquatic algae and cyanobacteria
Administrative data
- Endpoint:
- toxicity to aquatic algae and cyanobacteria
- Type of information:
- migrated 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: see 'Remark'
- Remarks:
- The presented data have been retrieved from US EPA's ECOTOX Database, Version 4 (2012). This database provides single chemical toxicity information for aquatic and terrestrial life. The concomitant information within the database (such as indentification of guidelines and methods used) is reduced to the necessary minimum and usually not reported. Nevertheless, the toxicity data deposited has been derived from peer-reviewed literature and can therefore be regarded as valid information.

Results and discussion
Effect concentrations
- Duration:
- 96 h
- Effect conc.:
- >= 1 000 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- element
- Remarks:
- Lithium
- Basis for effect:
- biomass
- Remarks on result:
- other: equivalent to >= 5559 mg/L Li3PO4
- Details on results:
- Conversion:
1000 mg/L : 6.94 u (atomic weight of Li) = 144.1 mmol/L
144.1 mmol/L : 3 = 48
48 x 115.82 (molecular weight of Li3PO4) = 5559 mg/L
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
