Description of key information
EC50 (48h) > 100 mg/L (nominal, vehicle used) for Daphnia magna (similar to OECD 202)
Key value for chemical safety assessment
Additional information
One study investigating the short-term toxicity of Diisononyl adipate (DINA) to aquatic invertebrates is available. The study was performed according to European standard test guideline, Directive 79/831/EWG, appendix V, part C, adopted in Nov 1989 (similar to OECD 202) under static conditions using Daphnia magna as test organism (BASF 1990). Concentrations between 0.049 and 100 mg/L were tested using a solubilizer (Cremophor RH 40). No mortality was observed in the control and treatments up to 50 mg/L during the exposure period of 48h. The 48h-EC50 is determined to be > 100 mg/L based on nominal concentrations.
