EC number: 240-521-2
CAS number: 16470-24-9
The following data are considered for the
evaluation of the classification of the substance for aquatic toxicity.
Short term toxicity
Fish: LC50 (96 h) > 1000 mg/l
Aquatic invertebrates: EC50 (48h) > 100
Algae: ErC50 (72h) > 123 mg/l (nominal);
NOEC (72h, growth rate) = 30.8 mg/l (nominal)
Fish: NOEC (fry length, fry weight) = 4.41
mg/l (TWA, mean measured)
Aquatic invertebrates:NOEC (21d, overall
threshold effects) = 1.10 mg/l
substance is determined to be not rapidly degradable and not
bioaccumulative considering its LogPow. No acute aquatic toxicity was
observed. Valid chronic toxicity data are available for Daphnia and fish
where the NOEC determined is > 1 mg/l. Therefore the substance is
not classified for the environment according to the Regulation (EC)
