Description of key information

Acutely toxic for aquatic invertebrates, analogy to 3,7-Dimethylocta-2,6-dienal (CAS 5392-40-5)

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
6.8 mg/L

Additional information

The acute toxicity of (Z)-3,7-Dimethylocta-2,6-dienal towards Daphnia magna was derived from the isomere Citral

(CAS 5392 -40 -5). For Citral, the toxicity to Daphnia was investigated in a study conducted according to the Directive 79/831/EEC, Appendix V, C2 (1984). The 48 h-EC50 was determined to be 6.8 mg/L (95% C.I.: 4.82 -8.78 mg/L). The highest concentration causing no effect (EC0) was 3.13 mg/L and the lowest concentration causing 100% immobility was 25 mg/L (all values refer to nominal concentrations).
