EC number: 700-748-4
CAS number: 1226911-69-8
acute studies based on international guidelines are available for the
three aquatic trophic levels (algae, aquatic invertebrates and fish). A
toxic effect was observed for the three aquatic trophic levels.
Aquatic invertebrates, Daphnia magna,
are the most sensitive species with a 48h-EC50 value at 1.1 mg/L based
on time-weighted mean concentrations.
For the algae Pseudokirchneriella
subcapitata, the 72h-ErC50 and 72h-ErC10 values based on growth rate
were determined to be 2.6 and 1.5 mg/L, respectively, based on
time-weighted mean concentrations.
For the fish, Danio rerio, the
96h-LC50 value was determined to be 4.07 mg/L based on the geometric
mean of the measured concentrations.
For micro-organisms, the effect of the test
item on the respiration of activated sewage sludge micro-organisms gave
a 3-Hour EC50 value of greater than 100 mg/L.
fate and pathways:
is not considered readily biodegradable and therefore it can
be considered as a potential Persistent (P) in the environment.
the registered substance is considered low mobile in soils with a
logKoc values at 2.86 (Koc=724) and with a log Kow value at 3.12,the substance
is not considered to be bioaccumulative according to CLP (< 4.0) and
No harmonised classification is
available on the registered substance. Nevertheless:
- the substance is not readily
- log Kow= 3.12
- For Daphnia and fish, 1
> lowest E(L)C50 value ≤
10 mg/L; and for algae, 1> ErC50 ≤ 10
Classification according to the
Annex VI of the Regulation(EC) No 1272/2008 (CLP): The registered
substance is classified for the environment as
Aquatic Toxic Chronic 2.
