Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

NOAEC
Value:
264.47 mg/m³
Explanation for the modification of the dose descriptor starting point:
Calculated using ECHAs Guidance on information requirements and chemical safety assessment Chapter R.8: Characterisation of dose [concentration]-response for human health (see justification and comments section for more information).
AF for dose response relationship:
1
Justification:
Default value from ECHAs Guidance on information requirements and chemical safety assessment Chapter R.8: Characterisation of dose [concentration]-response for human health as the result is a threshold effect (NOAEL) from a Klimisch 1 study and no other concerns regarding the results.
AF for differences in duration of exposure:
6
Justification:
Default value from ECHAs Guidance on information requirements and chemical safety assessment Chapter R.8: Characterisation of dose [concentration]-response for human health, sub-acute to chronic.
Justification:
Not required as this step has already been included during the route to route extrapolation step.
AF for other interspecies differences:
2.5
Justification:
Default value from ECHAs Guidance on information requirements and chemical safety assessment Chapter R.8: Characterisation of dose [concentration]-response for human health as there is no substance specific toxicokinetic information available.

Default value from ECHAs Guidance on information requirements and chemical safety assessment Chapter R.8: Characterisation of dose [concentration]-response for human health, workers.
AF for the quality of the whole database:
1
Justification:
Default value from ECHAs Guidance on information requirements and chemical safety assessment Chapter R.8: Characterisation of dose [concentration]-response for human health as there are no issues related to completeness and consistency of the available Klimisch 1 study.
