Description of key information
In a 72h acute toxicity limit test conducted according to the OECD guideline 201, Pseudokirchneriella subcapitata were exposed to E99434 at loading nominal rate of 100 mg/L. No toxicity on algae was observed at this loading rate. Therefore, the 72h-EL50 for cell growth was higher than 100 mg/L. As no effects were observed at the water solubility limit and at the loading rate tested no LOEC can be determined and no NOEC can be derived.
Key value for chemical safety assessment
Additional information
An experimental study was performed to determine the acute toxicity of E99434 to algae (Pseudokirchneriella subcapitata). The study was conducted according to the OECD guideline 201. Due to the negligible water solubility of test substance (<0.2 µg/L), a Water Accommodated Fraction (WAF) of the test substance was applied. The test substance was tested in a limit test at the nominal loading rate of 100 mg test item/L under semi-static conditions for 72 hours. Untreated dilution water was run in parallel as a control. Seven fish each were used at the test concentration and in the control. There were no toxic effects of the test item on Pseudokirchneriella subcapitata at the nominal loading rate of 100 mg test item/L. Thus, the 72h-EL50 for cell growth was determined to be >100 mg/L. As no effects were observed at the water solubility limit and at the loading rate tested no LOEC can be determined and no NOEC can be derived.
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).
