Description of key information

The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations. 
EC10 (30 min) 250 mg/L (nominal) for Pseudomonas putida (DIN 38412, part 27)

Key value for chemical safety assessment

Additional information

Since no data of the toxicity on microorganisms for the described pigment are available, a read-across to a similar pigment (CAS 81-77-6) is used to cover this endpoint. The respiration inhibition of the read-across substance to the bacteria Pseudomonas putida was investigated in a guideline study according to the German standard DIN 38412, part 27. After a 30 min exposure period, an EC10 of 250 mg/L (nominal) was determind [BASF AG 1991].
