Description of key information

(21 d) r/a NOEC 0.044-0.17 mg/L Daphnia magna (calculated)

Key value for chemical safety assessment

Additional information

The 21 day chronic NOEC of Daphnia magna has been calculated (QSAR) to lie in the range of 0.044 - 0.17 mg/L based on survival and reproduction (Schafers et al. 2009) for the similar substance undecanol CAS 112 -42 -5. This range is provided from reproduction effects to Daphnia magna. The reproduction effects were chosen as this is the most sensitive endpoint where the most conservative results are used.
