Additional information

To determine the toxicity of Methylbutinol to aquatic invertebrates, a non-GLP study following to EU method C.2 using Daphnia magna was performed. The calculated EC50 (48h) value in this study was >500 mg/L, related to the nominal concentrations (BASF SE 1988). Acute tests on marine organisms were performed using Chaetogammarus marinus in a semi-static approach. The non-guideline test revealed a LC50 (96h) of 359 mg/L, related to the nominal concentraion.
