Description of key information

According to the ECHA Guidance document R7b, no further test on the toxicity to microorganisms has to be conducted if the toxicity control in a ready biodegradability test shows no inhibitory effects on microorganisms. As the toxicity control in the Closed Bottle Ready biodegradability test showed no inhibition of the microbial activity at a substance concentration of 2 mg/L, no further test is necessary to evaluate the respiration inhibition of activated sludge. The concentration used in the toxicity control (2 mg/L) can be used as NOEC value.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
2 mg/L
