EC number: 941-167-8
CAS number: 1584709-99-8
Valid acute studies based on international
guidelines are available for the three aquatic trophic levels (algae,
aquatic invertebrates and fish). Among all data available, a toxic
effect was observed for the three aquatic trophic levels. The fish Danio
rerio is the most sensitive species with a 96h-LC50 value at 52.0
mg/L based on analytically confirmed nominal concentration. For the
algae Pseudokirchneriella subcapitata, the 72h-ErC50 and 72h-NOEC
values based on growth rate were determined to be greater than the
highest tested concentration 67.9 mg/L and 16.6 mg/L, respectively,
based on geometric mean measured concentrations. For the aquatic
invertebrates Daphnia magna, the 48h-EC50 value was determined to
be 108 mg/L based on analytically confirmed nominal concentration. In
addition, the registered substance was not toxic to activated sludge of
a municipal sewage treatment plant up to the nominal concentration of
Sediment, terrestrial toxicity and
hazard for predators
In the absence of any ecotoxicological data
for sediment-dwelling/soil organisms, the PNEC sediment/soil were
calculated using the equilibrium partitioning method (EPM). Furthermore,
no toxicity studies reporting the secondary poisoning effects on bird
were available, therefore the 28-day toxicity study on rats performed on
the registered substance was used to derive the PNECoral.
Environmental fate and pathways:
registered substance is considered readily biodegradable and therefore
(P) or very Persistent (vP) in the environment.
the registered substance is considered highly mobile in soils with a log
Koc values at 2.0 for soil (Koc = 100) and 2.1 for sewage sludge (Koc =
126), and with a log Kow value at 3.32, the substance is not considered
to be bioaccumulative according to CLP (< 4.0) and PBT criteria (< 4.5).
No harmonised classification is
available on the registered substance.
10 < lowest E(L)C50 value < 100 mg/L;
EC10 or NOEC algae > 1 mg/L; rapidly biodegradable; log Kow =
according to the Annex VI of the Regulation (EC) No 1272/2008 (CLP): The
registered substance is not classified for the environment.
