Additional information
All endpoints are based on measured data applying assessment factors.
The PNECaquatic is calculated using the assessment factor proposed by the TGD. As long-term NOECs from species representing three trophic levels are available (algae, daphnia and fish) an assessment factor of 10 may be used.
Conclusion on classification
Acute toxicity | Hazard | M-factor | ||
EL50 = 4.06 µg/L (nominal loading, algae) | H400 | 100 | ||
Chronic toxicity | Hazard | M-factor | ||
EL10 = 1.19 µg/L (nominal loading, algae) | H410 | 10 |
