3 acute aquatic toxicity studies are available on
3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctanesulphonic acid: a 96h acute
toxicity study on fish (OECD 203), a 48h immobility study on water flea
(OECD 202) and a growth inhibition study on a green alga (OECD 201). In
all three studies (see below), no adverse effects were observed at the
highest dose tested, which was always greater than 100 mg/L.
Nonetheless, all these studies were performed on an aqueous solution
containing 70% water and 30% active ingredient. As a result, the highest
concentrations tested were below 50 mg/L when corrected for the level of
active ingredient. Therefore, to support the assertion that
3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctanesulphonic acid does not
cause adverse effects on algae, aquatic invertebrates and fish up to
concentrations of 100 mg/L, studies on the corresponding potassium salt
of 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctanesulphonic acid were
included. On this potassium salt, 3 acute aquatic studies were available
(also on algae, aquatic invertebrates and fish) as well as an OECD 210,
90 day early life-stage study on rainbow trout.
