EC number: 254-996-9
CAS number: 40601-76-1
In short-term aquatic toxicity studies in fish and
daphnids, the test material caused no significant toxicity up to nominal
concentrations of 100 or 1000 mg/L, respectively. In a 72 -h study, the
test material did not produce significant toxicity in freshwater algae
up to a highest nominal concentration of 100 mg/L. The measured actual
concentration of the test material at the start of testing was 0.012
mg/L. The EC50 was reported as > 0.012 mg/L. The NOEC was reported as
0.012 mg/L. Key values of 100 mg/L for both the NOAE and EC50 were used
for the purposes deriving PNEC values. A value of 100 mg/L was the
starting value for PNEC calculations.
The equilibrium partitioning method was used to calculate
PNEC values for freshwater and marine sediment and soil. The EUSES
computer program, Version 2.1.1, was used for these calculations. The
molecular weight (699.94), Log Kow (15.28, calculated), and measured
water solubility (0.02 mg/L) were supplied to the program. All other
values were calculated internally applying default parameters.
A NOEC for activated sludge inhibition of 1000 mg/L was
the starting value for the calculation of a PNEC stp.
The substance is not classified.
