Description of key information
The inhibition of the degradation activity of activated sludge is not anticipated when the substance is introduced in appropriately low concentrations
Key value for chemical safety assessment
Additional information
The inhibitory effect of Orasol Pink 478 (CAS 97862-65-2) has been investigated in GLP guideline study performed according to OECD 209 (BASF SE, 2016; rep. no.: 08G0059/16G090). Activated sludge from a predominantly domestic sewage treatment plant was used as inoculum. The 180min EC10 was determined to be 140 mg/L, based on nominal test concentrations.
In conclusion, the inhibition of the degradation activity of activated sludge is not anticipated when the substance is introduced in appropriately low concentrations.
