Reference
Endpoint:
activated sludge respiration inhibition testing
Type of information:
other: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Remarks:
The complete read across justification is detailed in section 13. Test substance is an isomer of the substance under registration; structural difference is not expected to significantly impact the toxicity to microorganisms. Source study has reliability 2: only limited information available from a migrated NONS file, as per Article 25(3) request.
