EC number: 205-739-4
CAS number: 149-44-0
EC50 freshwater invertebrates (48 h): 50 mg/L
Following results were determined for the
test item (species: daphnia magna):
NOEC (48h): 100 mg/L
EC50i (24 h) > 100 mg/L
EC50i (48h) > 100 mg/L
The content of the test item was determined
by titration. Therefore, the determination of the biological results was
based on the nominal concentration.
Another study from 1999 showed also values
below 100 mg/L:
EC50 (24 h) > 160 mg/L
EC50 (48h) > 50 mg/L
Since no deviations from the guideline are
known, the study is considered as valid although it was no GLP study.
