Additional information
The acute toxicity of phthalonitrile (CAS 91-15-6) against fish was assessed in a guideline study according to OECD 203 with Oryzias latipes as test species (MITI, 2000). The fish were exposed to a series of 5 test concentrations and a control in a semi-static approach. The 96-h LC50 was 22.6 mg/L (nominal, analytically verified). This study was selected as key study.
Based on this result, phthalonitrile is considered to be acutely harmful to fish.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
