Description of key information
Additional information
Experimental studies investigating the short-term toxicity of
ammonium undecafluorohexanoate (CAS 21615-47-4) to aquatic organisms are
available. Moreover, chronic toxicity data are available for freshwater
fish and algae. All studies were performed according to standard OECD
guidelines. In the acute toxicity studies no effects up to 100 mg/L were
observed for aquatic invertebrates and algae. Only in the acute fish
study a LC50 (96 h) of 1850 mg/L was recorded which is far above the
limit concentration of 100 mg/L relevant for regulatory purposes. The
low toxicity of the substance to fish is further supported in two
chronic toxicity studies with fish (OECD 229 and EPA OPPTS 850.1400). No
effects on reproductive as well as endocrine parameters (larvae
mortality, length, dry weight, number hatched, vitellogenin and
fertility) were recorded. In addition no chronic effects on aquatic
algae were recorded (EC10 (72 h) > 100 mg/L). Thus, it can be concluded
that ammonium undecafluorohexanoate is of no hazard to aquatic organisms.
The effects of ammonium undecafluorohexanoate to activated sludge
microorganisms were further investigated in a study according to OECD
209. No effects on the respiration rate was recorded resulting in a
NOECD (3 h) ≥ 1000 mg/L. Thus, the degradation process in sewage
treatment plants is not considered to be inhibited by the test item.
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).
