Reference
Endpoint:
activated sludge respiration inhibition testing
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1989-06-02
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Justification for type of information:
The structure of the read-across substance is the para form of the CJ301 without the meta form. However, this difference does not influence the toxicity of the CJ301. CJ301 contains Li/Na salt form and the read-across substances contains only Na salt. This will not lead to difference on the toxicity results.
Qualifier:
according to
Guideline:
OECD Guideline 209 (Activated Sludge, Respiration Inhibition Test
Version / remarks:
1984
GLP compliance:
yes
Test type:
static
Remarks on exposure duration:
3hr
Duration:
3 h
Dose descriptor:
IC50
Effect conc.:
> 100 mg/L
Validity criteria fulfilled:
not specified

Description of key information

The result of IC50 (3hr) from read-across substance was more than 100 mg/L.

Key value for chemical safety assessment

EC50 for microorganisms:
100 mg/L
