Description of key information
Due to the high insolubility of the ZrC in water, aquatic toxicity is considered unlikely to occur. Hence, conducting aqautic toxicity studies with daphnia, algea and activated sludge is scientifically not necessary.
This is supported by available acute toxicity data on fish: ZrC did not cause mortality in Danio rerio when introduced in test aquaria at a nominal concentration of 100 mg/L (daily renewal of test solution, total exposure duration: 96 h).
Additional information
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.
