Description of key information
Additional information
The acute aquatic toxicity ofthis substance was evaluated using rainbow trout and was conducted in accordance withOECD 203. The 96 h LL (Lethal Loading Rate) 50 value of the substance was determined to be 4.4 mg/l. The No Observed Effect Loading rate was 3.2 mg/l loading rate WAF.
Then acute toxicity of this substance also was evaluated inDaphnia (OECD 202). The 48-Hour EL*50 was determined to be 75 mg/L nominal loading rate and the No Observed Effect Loading rate was 32 mg/l nominal loading rate.
The acute toxicity of this substance was evaluated in freshwater algae in accordance with OECD Guideline 201. Exposure ofScenedesmus subspicatusto the test material gave an EbL50 (72h) value of 240 mg/L loading rate WAF and an ErL50 (0-72hr) value of 410 mg/L loading rate WAF. The No Observed Effect Loading rate was 220 mg/L loading rate WAF.
Long term ecotoxicological data are available on a surrogate ZDDP substance for invertebrates and this ZDDP substance for algae. A 21 day reproduction test in Daphnia magna was conducted following OECD Guideline 211. Results from this study show that the NOEC for reproduction was 0.4 mg/L nominal (0.262 measured), and the NOEC for daphnid length and weight was 0.8 mg/L nominal.
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.
