Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
- Endpoint:
- toxicity to aquatic algae and cyanobacteria
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- February 2020
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- Validated QSAR calculation method, using ECOSAR v1.11 model. A QPRF is attached. The substances are within the scope of the EPISuite model data set, and is in model Applicability Domain. Further details can be found within the appended report below or at http://www.epa.gov/oppt/exposure/pubs/episuite.htm. This system is recognised in ECHA Guidance document CHAPTER R.6 – QSARS AND GROUPING OF CHEMICALS, Pg 47
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The substance is a multi-constituent substance of limited solubility. CLP classification is available for the individual components of the substance via REACH Annex VI harmonised classifications, REACH Registration dossiers or notifications to the CLP inventory. As such, it is deemed inappropriate to conduct additional testing on the reaction mass subject to this registration when the results may be predicted on the basis of the components themselves. QSAR assessment using US EPA On-Line EPI Suite™ ECOSAR v1.11 model assessment of Algal Inhibition is utilised to assess each component with the exception of phenol (which carries significant data already), with the associated range of results reported. Details on the US EPA On-Line EPI Suite™ ECOSAR v1.11 programme are detailed below.
