Long-term - systemic - inhalation
The hazard assessment of the target substance is based on the read-across substance, thermocracked kerosene (CAS 68333-23-3). The NOAEL for systemic effects is established from the dermal subacute (28-D; 5d/wk.) study in rats (Koschier, F.J., 1992).
Relevant dose descriptor NOAEL = 400 mg/kg/day, subacute, dermal exposure, rat (BP, 1992).
Modification of the dose descriptor according to ECHA Guidance R.8 (November 2012) Example B. 3.
100 % dermal absorption for rats
100 % inhalation absorption regardless of species
Corrected inhalatory NOAEC = dermal NOAEL * (1/ sRVrat 8h) * (ABSdermal-rat/ ABSinh-human) * (sRVhuman8h/ wRV) ABS – absorption
sRVrat – respiratory volume under standard conditions = 0.38 m3/kg/d
sRVhuman- respiratory volume under standard conditions = 6.7 m3 (8h)
wRV - respiratory volume light activity for worker = 10 m3 (8h)
Corrected inhalatory NOAEC= 400 * (1/0.38) * (100/100) * (6.7 / 10)
Corrected inhalatory NOAEC = 705.26 mg/m3
Assessment factors according to ECHA 2012 Guidance R.8 Characterization of dose response to human health
Interspecies - remaining differences 2.5
Intraspecies differences for workers 5
Exposure duration - subacute to chronic 6
Issues related to dose responses - the starting point for the DNEL calculation is a derived NOAEL - default assessment factor 1 Quality of whole database - default assessment factor 1
Overall AF 2.5 * 5 * 6 * 1 * 1 = 75
DNEL worker inhalation= 705.26 mg/m3/ 75 = 9.40 mg/m3
