Description of key information
Additional information
Three acute freshwater ecotoxicological studies were conducted: a fish, a daphnia and an alga. The least sensitive species was the fish with an LL50 value of 70.7 mg/L. Because BADGE IPD (#33) has cationic properties, the testing medium was augmented with humic acid, per EPA 1996 (OPPTS 850.1085), in the species predicted to be the most sensitive: the alga. The addition of humic acid reduced the toxicity of BADGE MXDA (#42) to algae from 1.67 mg/L to 79.4 mg/L. This made acute daphnia EL50 (11.1 mg/L) the most sensitive endpoint. Therefore, the daphnia data were used to derive the freshwater, marine and intermittent release PNECs.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
