Description of key information

C8-18 AAPHS has no inhibitory effect on the respiration rate of activated sludge after the incubation period of three hours up to and including the test concentration of 2762 mg test item/L, corresponding to 1000 mg C8 -18 AAPHS /L. The 3h EC50 is therefore >1000 mg C8-18 AAPHS /L and is considered appropriate for read-across purposes to C12 -14 AAPHS.

Key value for chemical safety assessment

EC50 for microorganisms:
1 000 mg/L
EC10 or NOEC for microorganisms:
1 000 mg/L
