Additional information
Acute toxicity to fish was tested for several species.The studies which were reliable and selected as key studies were conducted on trout (Salmo gairdneri) and bluegill (Lepomis macrochirus). These reported 96 hour LC50 as 75 mg/liter. Test conditions were static and test material concentrations were not measured. Effects were observed only in the highest concentration (100 mg/liter); initial pH was 3.3 in that concentration, suggesting that toxicity was related to acidity. Dilution water was soft reconstituted water (total hardness of 40 to 45 mg/liter as CaCO3) with temperatures of 12ºC (trout) and 22ºC (bluegill).
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.
