Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
activated sludge respiration inhibition testing
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is found to be readily biodegradable and the applied test concentrations are in the range of concentrations that can be expected in the influent of a sewage treatment plant
GLP compliance:
yes

Description of key information

The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations.

Key value for chemical safety assessment

Additional information

This endpoint is sufficiently covered by the data on biodegradability (please see Section 5.2).

The results of the key study in Section 5.2 indicate that

a) sodium formate is readily biodegradable,

b) disturbances in sewage treatment plants are not to be expected when sodium formate is released in appropriate amounts, and

c) inhibitory effects of sodium formate to sewage sludge bacteria were not observed at the tested concentration 22.1 mg/L.
