Toxicological Summary
Administrative data
Workers - Hazard via inhalation route
Systemic effects
Long term exposure
- Hazard assessment conclusion:
- DNEL (Derived No Effect Level)
- Value:
- 4.4 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):
- 40
- Dose descriptor starting point:
- NOAEL
- Value:
- 200 mg/kg bw/day
- Modified dose descriptor starting point:
- NOAEC
- Value:
- 176 mg/m³
- Explanation for the modification of the dose descriptor starting point:
Starting from a NOAEL of 200 mg/kg in a subchronic oral study in rats a NOAEC of 176 mg/m³ was derived.
- AF for dose response relationship:
- 1
- Justification:
- ECHA default value
- AF for differences in duration of exposure:
- 2
- Justification:
- The starting point was a 90 day study; ECHA default factor
- AF for interspecies differences (allometric scaling):
- 4
- Justification:
- Values were extrapolated from rat to human; ECHA-default factor
- AF for other interspecies differences:
- 1
- Justification:
- Included in allometric scaling
- AF for intraspecies differences:
- 5
- Justification:
- ECHA.default value
- AF for the quality of the whole database:
- 1
- Justification:
- The data formimg the basis of this assessment are from reliable animal studies.
- AF for remaining uncertainties:
- 1
- Justification:
- No remaining uncertainties are considered.
