Additional information

To determine the toxicity of Dibutyl phthalate to aquatic invertebrates, a GLP study following the method laid down in Directive 92/69/EEC using Daphnia magna was performed. The calculated EC50 (48h) value in this study was 3.4 mg/L, related to the measured concentrations (Hüls AG 1994).
