Additional information

Based on the acute results of the 3 trophic levels, the chronic daphnia results and the outcome of the resultant chemical safety assessment, the performance of a long-term fish test will have no added value to the risk assessment process

Conclusion on classification

Acute classification

The existing acute data for fish, algae and Daphnia show a NOEC value > maximum achievable water solubility. As all effect values are above 1 mg/L,there is no acute classification for this substance.

Chronic classification

Substance is inherentlybiodegradable, and the measured log Kow is 4.84. The chronic data available are 72 h ErC10 algae, 20.23 mg/L, loading) and Daphnia (NOEC of 2.7 mg/L). When chronic data for less than 3 trophic levels are available the classification is assessed using both the existing chronic and acute data, and the most stringent outcome is chosen.

Based on chronic data: (72 h ErC10 algae, 20.23 mg/L): No classification

Based on acute data (NOECs > maximum water solubility): No classification

Category chronic 4 evaluation- Substance is poorly water soluble, with no acute toxicity recorded up to the water solubility, is not rapidly degradable and the log Kow > 4. However the chronic toxicity NOEC > water solubility and 1 mg/L, thus it does not fit into this category

Most stringent outcome: None

Overall classification: None
