Toxicological Summary
Administrative data
Workers - Hazard via inhalation route
Systemic effects
Long term exposure
- Hazard assessment conclusion:
- DNEL (Derived No Effect Level)
- Value:
- 35.26 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:
- NOAEC
- Modified dose descriptor starting point:
- NOAEC
- Value:
- 881.58 mg/m³
- Explanation for the modification of the dose descriptor starting point:
Justification for route to route extrapolation:
No available data on inhalatory study; therefore DNEL is derived from oral study route.
Inhalatory N(L)OAEC=oral N(L)OAEL*(1/0.38 m3/kg/d)*0.67*(ABSoral/ABSinh), assuming ABSoral/ABSinh= 0.5
- AF for dose response relationship:
- 1
- Justification:
- starting point NOAEC
- AF for differences in duration of exposure:
- 2
- Justification:
- Subchronic to chronic
- AF for interspecies differences (allometric scaling):
- 1
- Justification:
- Not applicable
- AF for other interspecies differences:
- 2.5
- Justification:
- Default factor
- AF for intraspecies differences:
- 5
- Justification:
- Workers
- AF for the quality of the whole database:
- 1
- AF for remaining uncertainties:
- 1

Systemic effects
Long term exposure
- Hazard assessment conclusion:
- DNEL (Derived No Effect Level)
- Value:
- 10 mg/kg bw/day
- Most sensitive endpoint:

- Route of original study:
- Oral
DNEL related information
- DNEL derivation method:
- ECHA REACH Guidance
- Overall assessment factor (AF):
- 100
- Modified dose descriptor starting point:
- NOAEL
- Value:
- 1 000 mg/kg bw/day
- Explanation for the modification of the dose descriptor starting point:
Justification for route to route extrapolation:
No available data on dermal study; therefore DNEL is derived from oral study route.
Dermal N(L)OAEC = oral N(L)OAEL*(ABSoral/ABSdermal), assuming ABSoral/ABSdermal = 1
- AF for dose response relationship:
- 1
- Justification:
- starting point NOAEL

- Subchronic to chronic
- AF for interspecies differences (allometric scaling):
- 4
- Justification:
- Rat to human
- AF for other interspecies differences:
- 2.5
- Justification:
- Default factor
- AF for intraspecies differences:
- 5
- Justification:
- Workers
- AF for the quality of the whole database:
- 1
- AF for remaining uncertainties:
- 1
