CAS number: 1226911-69-8
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.
Aquatic invertebrate, 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.
Although not requested under REACH Annex
VII, the vertebrate acute fish and ASRIT studies were performed to
comply with worldwide regulations.
