Workers - Hazard via inhalation route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
25.6 mg/m³
Most sensitive endpoint:
repeated dose toxicity
Route of original study:
By inhalation
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
11
Dose descriptor starting point:
NOAEC
Value:
560 mg/m³
Modified dose descriptor starting point:
NOAEC
Value:
281.4 mg/m³
Explanation for the modification of the dose descriptor starting point:

The following correction was made to the NOAEC (inhalation): Correction for experimental exposure duration (6 h/d to 8 h/d), Correction for respiratory volume (worker): 6.7 m3/10 m3. Therefore the corrected NOAEC for repeated-dose systemic effects via the inhalation route is: 560*(6 h/ 8 h) *(6.7 m3/10 m3) = corrected NOAEC 281.4 mg/m3.

AF for dose response relationship:
