Description of key information
With high probability acutely not harmful to aquatic invertebrates.
Key value for chemical safety assessment
Additional information
As key study a static GLP study following the method laid down in Directive 79/831/EWG, method C.2 using Daphnia magna to determine the toxicity of 1,4-Dimethyl-1H-pyrazole (CAS 1072 -68 -0) to aquatic invertebrates was identified (BASF, 1995). It was performed with four concentrations plus control ranging from 12.5 to 100 mg/L. The calculated EC50 (48h) value in this study was > 100 mg/L, related to the nominal concentration. Measured concentrations ranges from 96 - 102 % of the nominal concentration throughout the test. It can be concluded that the substance is with high probability acutely not harmful to aquatic invertebrates.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
