Additional information

To determine the toxicity of N-(2-ethylhexyl)naphthalen-2-amine to algae, a non-GLP study following the method laid down in OECD TG 201 using Desmodesmus subspicatus was performed by the Fraunhofer Institute on behalf of BASF SE (1990). The calculated EC50 value after 72 hours of test duration was 0.24 mg/l, related to the nominal concentrations.
