Description of key information

EC50 freshwater invertebrates (48 h): 50 mg/L

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
50 mg/L

Additional information

Following results were determined for the test item (species: daphnia magna):

NOEC (24h): 100 mg/L

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.
