Workers - Hazard via inhalation route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
4.02 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):
50
Dose descriptor starting point:
NOAEL
Value:
228 mg/kg bw/day
Modified dose descriptor starting point:
NOAEC
Value:
201 mg/m³
Explanation for the modification of the dose descriptor starting point:

Exposure via the oral route is considered a more appropriate route of exposure than inhalation as the physical chemical properties such as physical state (liquid at room temperature and pressure) and vapour pressure indicate that exposure via inhalation is unlikely. Thus, testing via the oral route was suitable for classification and risk assessment.
