EC number: 208-419-2
CAS number: 527-60-6
Growth rate 0 - 96hours (x10,000)
Nominal conc. (mg/L)
Measured Interpolated Conc. (mg/L)
According to OECD 201 and in compliance with
GLP, a growth inhibition test was performed on fresh water green alga
(selenastrum capricornutum). A
range-finding test was conducted (0, 0.08, 0.8, 8, 80, and 800 mg/L; as
test product) to determine the test concentrations to be used for the
definitive test. For the definitive test nominal concentrations were 0,
0.82, 2.05, 5.12, 12.8, 32.0, and 80.0 mg/L (4 replicates per
concentration or control). In the definitive test, the test
concentrations that were not analytically verified were interpolated
from the measured test concentrations. All concentrations were then time
weighted (OECD, 1998b). Based on the time-weighted concentrations, the
96-hour ECr50 is 6.03 mg/L and the 96-hour NOECr is 1.61 mg/L. Based on
the nominal concentrations, the 96-hour ECr50 is 8.64 mg/L and the NOECr
is 2.05 mg/L.
