Description of key information
The 96 h LC50 of Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters in freshwater fish was >200 mg/L.
Key value for chemical safety assessment
Additional information
In a 96-h acute toxicity study according to OECD guideline 203 (1992) and EU method C.1 (2008), Danio rerio (zebra fish) were exposed to Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters at nominal loading rates of 0 (control) and 200 mg/L under static conditions. Since a water accommodated fraction of the test item was tested, the reported biological results were based on the loading rate of the test item.
In the control and at the loading rate of 200 mg/L, no mortality or other visible abnormalities were determined at the test fish during the test period of 96 hours.
Therefore, the 96-hour NOEC of Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters to zebra fish were determined to be at the loading rate of 200 mg/L. The 96-hour LC50 was higher than the loading rate of 200 mg/L.
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.
