Toxicological Summary
Administrative data
Workers - Hazard via inhalation route
Systemic effects
Long term exposure
- Hazard assessment conclusion:
- DNEL (Derived No Effect Level)
- Value:
- 1.763 mg/m³
- Most sensitive endpoint:
- repeated dose toxicity
- Route of original study:
- Oral
DNEL related information
- DNEL derivation method:
- ECHA REACH Guidance
- Overall assessment factor (AF):
- 25
- Dose descriptor starting point:
- NOAEL
- Value:
- 50 mg/kg bw/day
- Modified dose descriptor starting point:
- NOAEC
- Value:
- 44.079 mg/m³
- AF for dose response relationship:
- 1
- Justification:
- based on NOAEL
- AF for differences in duration of exposure:
- 2
- Justification:
- based on RDT study 90 days
- AF for interspecies differences (allometric scaling):
- 1
- Justification:
- Af not used for inhalation route - already included in route-to-route extrapolation.
- AF for other interspecies differences:
- 1
- Justification:
- Due to the properties of the substance, a serious dangerous effect is not expected and the AFs used are sufficient
- AF for intraspecies differences:
- 5
- Justification:
- workers
- AF for the quality of the whole database:
- 1
- Justification:
- Reliability 1
- AF for remaining uncertainties:
- 2.5
