Long term exposure
- Hazard assessment conclusion:
- DNEL (Derived No Effect Level)
- Value:
- 1.32 mg/m³
- Most sensitive endpoint:
- repeated dose toxicity
- Route of original study:

- Modified dose descriptor starting point:
- NOAEC
- Value:
- 98.68 mg/m³
- Explanation for the modification of the dose descriptor starting point:
repeated dose toxicity NOAEL = 80 mg/kg bw /day
NOAEC = NOAEL x 2.63 (correction factor for differences in respiratory volume) x 0.5 (correction for differences in bioavailability) x 0.67 (correction for light activity at work) x 1.4 (correction for differences between human and experimental exposure conditions, workers) = 98.68 mg/m3
- AF for differences in duration of exposure:
- 6
- Justification:
- sub acute to chronic
- AF for other interspecies differences:
- 2.5
- AF for intraspecies differences:
- 5
- Justification:
- worker factor

- Most sensitive endpoint:
- repeated dose toxicity
- Route of original study:
- Oral
DNEL related information

- Overall assessment factor (AF):
- 300
- Modified dose descriptor starting point:
- other: NOAEC
- Value:
- 112 mg/kg bw/day
- Explanation for the modification of the dose descriptor starting point:
The most sensitive available end point is the repeated dose toxicity oral for which DNEL dermal is derived.
repeated dose toxicity NOAEL = 80 mg/kg bw /day
NOAEC = NOAEL x 1.4 (correction for differences between human and experimental exposure conditions, workers) = 112 mg/m3
- AF for differences in duration of exposure:
- 6
- AF for interspecies differences (allometric scaling):
- 4
- AF for other interspecies differences:
- 2.5
- AF for intraspecies differences:
- 5
Acute/short term exposure
- Hazard assessment conclusion:
- no hazard identified
- Most sensitive endpoint:
- acute toxicity
- Route of original study:
- Oral
DNEL related information
- Explanation for the modification of the dose descriptor starting point:
The substance is not classified for acute toxicity hazards for this reason no acute DNEL(S) need to be calculated
Local effects
