Additional information

The PNECaquatic (freshwater) for vinyl neononaoate is 4.2 ug/L and the PNECmarine is 0.42 ug/L are believed to represent safe concentrations for the aquatic environment. The PNECstp of > 5 mg/L suggest that vinyl neononanoate will not impact the efficient operation of sewage treatment plants.

Conclusion on classification

Based on acute aquatic study findings with a low LC50 value of 4.2 mg/L vinyl neononanoate is believed to be harmful to aquatic organisms and may cause long-term adverse effects in the aquatic environment because the substance does not readily biodegrade.
