Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
activated sludge respiration inhibition testing
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Principles of method if other than guideline:
No guideline is required for QSAR.
Key result
Nominal / measured:
nominal
Conc. based on:
test mat.
Remarks on result:
not determinable
Remarks:
The QSAR model does not predict a quantitative result but confirms that sodium pyruvate is non-toxic to microorganisms.
Executive summary:

The prediction made by QSAR is NON-Toxic, the result appears reliable.


For the assessment a value of >= 10 mg/L is assumed for both NOEC and EC50.


Reliability 3/3

Description of key information

For the assessment a value of >= 10 mg/L is assumed for both NOEC and EC50.

Key value for chemical safety assessment

EC50 for microorganisms:
10 mg/L
EC10 or NOEC for microorganisms:
10 mg/L
