Description of key information
The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations.
Key value for chemical safety assessment
Additional information
Experimental data on the acute toxicity of CAS 693 -98 -1 to microorganisms are available.
A guideline study according to DIN 38412, part 8 with Pseudomonas putida as test species was performed. In this study the 7-h EC10 value (growth inhibition) for the test item was determined to be about 193 mg/L (BASF AG 9/1890091,1989).
Therefore, the inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations.
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).
