Description of key information

Additional information

The substance is not acutely toxic to aquatic organisms. 

Chronic toxicity data are available for three trophic levels (fish, aquatic invertebrates and algae). 

- Algea study (OECD 201) on 6:2 FTMA (test substance) without any significants effects at the limit of solubility, NOEC (72h)=0,0078 mg/L (Safepharm, 2005)
- Invertebrates study (OECD 211) on 6:2 FTOH (degradation product) with NOEC (21d)= 2,57 mg/L
(DuPont Haskell Global Centers for Health & Environmental Sciences, 2013)
- Fish study (OECD 234) on 6:2 FTOH (degradation product) with a NOEC at 0.0137 mg/L which
corrected for molecular weight differences between 6:2 FTMA (432 g/mol) and 6:2 FTOH (364 g/mol) substances, would yield an equivalent 6:2 FTMA NOEC of 0.0162 mg/ (=0.0137x432/364=0.0162)
