Description of key information

Daphnia magna was exposed under static conditions for 48 hours to one concentration of HDI oligomers, iminooxadiazindione. Analysis of the immobilisation rates showed an EL0 of ≥100 mg/L.
The results are expressed in terms of effective loadings (EL) at 24h and 48h. Considering the heterogeneous composition of the test item, Water Accommodated Fractions WAF's) were tested. The results of the DOC determinations reflect a rough impression only of exposure
conditions over time. No informations are available on a potential correlation between effective loadings and measured DOC values. Up to the waten solubility of the test item under exposure conditions no toxic effects were determined.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
100 mg/L

Additional information

The key value should read ≥ 100 mg/L as no EC50 could be determined at the limit test concentration of 100 mg/L.
