Toxicological information
Toxicological Summary
Administrative data
Workers - Hazard via inhalation route
Systemic effects
Long term exposure
- Hazard assessment conclusion:
- DNEL (Derived No Effect Level)
- Value:
- 70.5 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
- Modified dose descriptor starting point:
- NOAEC
- Value:
- 1 763.2 mg/m³
- Explanation for the modification of the dose descriptor starting point:
- NOAECcorr = NOAELoral*(1/0.38 m³/kg/d)*(ABSoral-rat/ABSinh-human)*(6.7 m³ (8h)/10 m³ (8h)) = 1000 mg/kg/d*(1/0.38 m³/kg/d)*(1*1)*0.67 = 1763.2 mg/m³
- AF for dose response relationship:
- 1
- AF for differences in duration of exposure:
- 2
- Justification:
- DNEL is based on an oral 90-day study
- AF for interspecies differences (allometric scaling):
- 1
- Justification:
- AF for allometric scaling already included in ECHA starting point derivation method; no further factor required.
- AF for other interspecies differences:
- 2.5
- AF for intraspecies differences:
- 5

- 1
- AF for remaining uncertainties:
- 1

- Modified dose descriptor starting point:
- NOAEL
- Value:
