Description of key information
In Annex IX of Regulation (EC) No 1907/2006, it is laid down that chronic toxicity tests shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on invertebrates.
However, there is no need to conduct further long-term testing as:
The quantitative safety assessment showed PEC/PNEC well below 1 for all identified uses - despite that a high assessment factor for the derivation of the PNECs for fresh and marine water was applied.
The substance is readily biodegradable so it will not persist in the environment
The short-term toxicity tests showed no unexpected sensitivity of a group of organisms to the substance
Therefore, a long-term toxicity study in Daphnia is not providedKey value for chemical safety assessment
