AD-1000 is not classified for acute oral, dermal and inhalation toxicity and therefore, no acute DNELs have to be derived.The long-term DNEL is considered sufficient to ensure that effects from acute exposure to the substance do not occur (in accordance with ECHA Guidance on information requirements and chemical safety assessment: Chapter R.8: Characterisation of dose [concentration]-response for human health, May 2008 and Part B: Hazard Assessment, Draft new chapter B.8 Scope of Exposure Assessment, March 2010).
DNELs for local effects will not be derived, as no local effects in repeated dose studies were observed.
The following DNELs for workers will be derived:
Systemic:
Long-term inhalation workers
Long-term dermal workers
Route-to-route extrapolation
For the derivation of the DNELs:
Long-term – dermal, systemic effects
Long-term – inhalation, systemic effects
Route-to-route extrapolation has been performed. In absence of relevant data, only differences between the different routes as determined by the assumed percentages of absorption into the systemic circulation could be accounted for (see toxicokinetic assessment).
Absorption oral (rat) = Absorption oral (human) = 10%
Absorption dermal (human) = 10%
Absorption inhalation (human) = 100%
The DNELs for human exposure are derived according to the ECETOC guidance (Technical Report No.110, October 2010).
Starting point for DNEL derivation: NOAEL ≥1000 mg/kg bw/day from an oral 28-day study in rats (highest dose tested, no effects)
Long-term inhalation, systemic effects
Route-to-route extrapolation:
Inhalation NOAEL = oral NOAEL * ABSoral-rat/ABSinh-human = 1000 * 10/100 = 100 mg/kg bw
Corrected inhalatory NOAEC = 100 * 1/0.38 * 6.7 m3/10 m3= 176 mg/m3
Safety factors:
- Interspecies extrapolation: 1
- Intraspecies extrapolation: 3
- Exposure duration: 6 (assuming chronic worker exposure)
- Dose response: 1
- Quality of the data base: 1
Total safety factor: 18
Based on the above, the long-term DNEL for systemic effects after inhalation exposure of the worker, is set at 9.8 mg/m3.
Long-term dermal, systemic effects
Route-to-route extrapolation:
Dermal NOAEL = oral NOAEL * ABSoral-rat/ABSderm-human = 1000 * 10/10 = 1000 mg/kg bw
Safety factors:
- Interspecies extrapolation: 4
- Intraspecies extrapolation: 3
- Exposure duration: 6 (assuming chronic worker exposure)
- Dose response: 1
- Quality of the data base: 1
Total safety factor: 72
Based on the above, the long-term DNEL for systemic effects after dermal worker exposure is set at 14 mg/kg bw/day.
