Workers - Hazard via inhalation route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
1.18 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):
75
Dose descriptor starting point:
LOAEL
Value:
100 mg/kg bw/day
Modified dose descriptor starting point:
LOAEC
Value:
88.16 mg/m³
Explanation for the modification of the dose descriptor starting point:

Available data do not suggest a pronounced difference between oral and inhalation route. Due to a lack of experimental data the LOAEC (corr) was derived including ECHAs recommended absorption rates for exposure via the oral (50 %) and inhalation (100 %) route.

AF for dose response relationship:
1
Justification:
default
AF for differences in duration of exposure:
2
Justification:
extrapolation from sub-chronic to chronic (default)
AF for interspecies differences (allometric scaling):
1
Justification:
default (inhalation)
AF for other interspecies differences:
2.5
Justification:
default
AF for intraspecies differences:
5
Justification:
default (worker)
AF for the quality of the whole database:
1
Justification:
default
AF for remaining uncertainties:
3
Justification:
Uncertainty based on the lack of a NOAEL for male rats (DNEL derived from LOAEL)
Acute/short term exposure
Hazard assessment conclusion:
no hazard identified
DNEL related information

Local effects

Long term exposure

Workers - Hazard via dermal route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
0.67 mg/kg bw/day
Most sensitive endpoint:
repeated dose toxicity
Route of original study:
Oral
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
300
Dose descriptor starting point:
LOAEL
Value:
100 mg/kg bw/day
Modified dose descriptor starting point:
LOAEL
Value:
200 mg/kg bw/day
Explanation for the modification of the dose descriptor starting point:

Available data do not suggest a pronounced difference between oral and dermal route. Due to a lack of experimental data the LOAEL (corr) was derived including absorption rates for exposure via the oral (100 %) and dermal (50 %) route.
