The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
As key study regarding toxicity to microorganisms a non-GLP test
according to OECD guideline 209 was performed using domestic activated
sludge as inoculum. After 30 minutes of exposure no respiration
inhibition could be observed resulting in a EC0 of 1000 mg/L (BASF
90/1170/08/1, 1990). As a further result an EC10 (16h) of 95 mg/L from a
test with Pseudomonas putida is available (BASF 1990). For PNEC
derivation the EC0 values from the OECD 209 test is used as the test is
more realistic for the assessment of toxicity to sewage works.
