Description of key information
DPHP is with high probability acutely not harmful to aquatic invertebrates. No toxic effects occur within the range of solubility.
Key value for chemical safety assessment
Additional information
To determine the toxicity of DPHP to aquatic invertebrates, a GLP study according to EEC Directive 79/831/EEC using Daphnia magna as test organism was carried out. Based on the nominal concentration the EC50 (48 h) was determined to be > 100 mg/L [BASF 1995].
