Workers - Hazard via inhalation route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
2.939 mg/m³
Most sensitive endpoint:
repeated dose toxicity
Route of original study:
Oral
DNEL related information
Overall assessment factor (AF):
225
Dose descriptor starting point:
LOAEL
Value:
250 mg/kg bw/day
Modified dose descriptor starting point:
LOAEC
Value:
220.4 mg/m³
AF for dose response relationship:
3
Justification:
based on LOAEL
AF for differences in duration of exposure:
6
Justification:
based on 28-d RDT study
AF for interspecies differences (allometric scaling):
1
Justification:
AF not used for inhalation route - already included in route-to-route
AF for other interspecies differences:
1
Justification:
Due to the properties of the substance, a serious dangerous effect is not expected and the AFs used are sufficient.
AF for intraspecies differences:
5
Justification:
AF for workers
AF for the quality of the whole database:
1
Justification:
Reliability 1
AF for remaining uncertainties:
