EC number: -
CAS number: -
aquatic toxicity studies of reliabilities 1 or 2 (Klimisch rating),
based on international guidelines, are available on the registered
substance for aquatic invertebrates and algae. According to these
results, the aquatic invertebrates Daphnia magna was considered
to the most sensitive species. The 48h-EC50 value based on mobility on D.
magna was determined to be 1.8 mg/L (95% CL: 1.0 - 3.3 mg/L) and the
72h-ErC50 value based on growth rate on Pseudokirchneriella
subcapitata was determined to be greater than the highest tested
concentration, 2.67 mg/L. However, a 72h-ErC10 value based on growth
rate on P. subcapitata was determined at 1.54 mg/L(95%
CL: 1.02 - 2.28 mg/L).
Environmental fate and pathways
The registered substance is not
considered readily biodegradable but there is unequivocal evidence of
primary biodegradation within 60 days. Therefore, the registered
substance is considered inherently biodegradable. In addition, the
extensive bioaccumulation assessment of the registered substance
confirms that the substance is not bioaccumulable in aquatic organisms.
No harmonised classification is
1 mg/L < lowest EC50 value < 10 mg/L;
EC10 value > 1 mg/L; not readily biodegradable with a log Kow > 4.0 and
BCF > 500.
according to the Annex VI of the Regulation (EC) No 1272/2008 (CLP): The
registered substance is classified as Aquatic Chronic 2 for the
