Additional information

Conclusion on classification

The results from aquatic toxicity studies are as follow:

- Short-term toxicity to fish. Key study: LC50 (96h) = 1011.11 mg/L (based on mortality) (read-across from supporting substance butanone oxime).

- Long-term toxicity to fish. Key study: LC50 (14d) > 119.94 mg/L (based on mortality) and NOEC (14d) = 59.97 mg/L (read-across from supporting substance butanone oxime).

- Short-term toxicity to aquatic invertebrates: Key study: EC50 (48h) = 241.08 mg/L (based on mobility) (read-across from supporting substance butanone oxime).

- Long-term toxicity to aquatic invertebrates: Key study: LC50 (21d) > 119.94 mg/L (based on parental mortality), EC50 (21d) > 119.94 mg/L (based on reproduction) and NOEC (21d) >= 119.94 mg/L (based on reproduction) (read-across from supporting substance butanone oxime).

- Toxicity to aquatic algae: Key study: EC50 (72h) = 19.19 mg/L and NOEC (72h) = 3.12 mg/L (based on growth rate) (read-across from analogue substance butanone oxime)

Based on the results from the aquatic toxicity tests, the substance the substance butan-2-one O,O',O''-(vinylsilanetriyl)oxime is not classified for aquatic toxicity according to CLP Regulation (EC) No. 1272/2008.
