Route-to-route extrapolation
Necessary for the long-term systemic dermal DNEL for the general population and workers.
For both oral and dermal absorption, 100% is assumed based on a toxicokinectic assessment.
Derivation of DNELs
The DNELs for human exposure are derived according to the ECETOC guidance (Technical Report No. 110, October 2010).
Long-term dermal, systemic effects
Worker
Starting point: NOAEL of ≥ 10000 mg/kg bw/day from an oral chronic toxicity study in rats with glycerol.
Corrected dermal NOAEL = 10000 x 100/100 = 10000 mg/kg bw/day
Safety factors:
- Interspecies extrapolation: 4
- Intraspecies extrapolation: 3
- Exposure duration: 1
- Dose response: 1
- Quality of the data base: 1
Total safety factor: 12
Based on the above, the long-term DNEL for systemic effects after dermal worker exposure is set at 833 mg/kg bw/day.
Long-term inhalation, systemic effects
Worker
Starting point: NOAEC of ≥ 662 mg/m3 from a 13 -week inhalation study in rats (exposure 6 hours/day, 5 days/week).
Corrected inhalatory NOAEC = 662 * 6h/8h * 6.7 m3/10 m3= 333 mg/m3.
Safety factors:
- Interspecies extrapolation: 1 (not applicable for inhalation route)
- Intraspecies extrapolation: 3
- Exposure duration: 2 (assuming chronic worker exposure)
- Dose response: 1
- Quality of the data base: 1
Total safety factor: 6
Based on the above, the long-term DNEL for systemic effects after inhalation worker exposure is set at 55 mg/m3.
Long-term inhalation, local effects
Worker
Starting point: NOAEC of 165 mg/m3 from a 13-week inhalation study in rats (exposure 6 hours/day, 5 days/week).
Corrected inhalatory NOAEC = 165 mg/m3(no time scaling and no correction for ventilation rate are considered necessary for local effects).
Safety factors:
- Interspecies extrapolation: 1 (not applicable for local effects)
- Intraspecies extrapolation: 3
- Exposure duration: 1 (not applicable for local effects)
- Dose response: 1
- Quality of the data base: 1
Total safety factor: 3
Based on the above, the long-term DNEL for local effects after inhalation worker exposure is set at 55 mg/m3.
