Ecotoxicological information

Toxicity to aquatic algae and cyanobacteria

Administrative data

Endpoint:
toxicity to aquatic algae and cyanobacteria
Type of information:
migrated information: read-across based on grouping of substances (category approach)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Category is coherent for more than 10 endpoints. Ecotoxicological effect is non specific, linked to surfactant properties and no functional groups are present that may be associated with known specific ecotoxicity.
