Additional information

The UVCB substance WS400130 did not exhibit toxic effects to aquatic organisms of three trophic levels in acute and long-term studies up to the limits of its water solubility. Therefore, no PNECs for aquatic compartments can be derived.

The substance has a very low vapour pressure and thus exposure via air is unlikely.

For the terrestrial compartment a PNEC of 5.8 mg/kg standard soil dw was derived. However, it is very unlikely that the substance will enter the soil compartment upon normal use.

In the oral repeat dose study in rats no toxic effects were observed at the highest dose of 1000 mg/kg body weight/day. Thus, a DNEL and correspondingly a PNEC for secondary poisoning cannot be derived.

Conclusion on classification

Based on the results of the available studies no classification for environmental hazards is necessary according to European classification rules [Regulation (EC) 1272/2008].
