EC number: 203-002-1
CAS number: 102-06-7
Correction factor for differences in respiratory volume (rat/workers): 1/0.38
Correction factor for light activity at work : 6.7/10
Correction factor for difference between human and experimental exposure conditions : 7/5 (In the study, animals were exposed 7 days per week, and workers work 5 days per week).
Oral absorption = 100 % (see section 7.1 Toxicokinetics)
Inhalation absorption = 100% (see section 7.1 Toxicokinetics)
LOAEC = LOAEL x (1/0.38) x (6.7/10) x 7/5= 5 x (1/0.38) x (6.7/10) x 7/5 = 12.3 mg/m3
Based on the TK assessment, a dermal absorption of 10% was used.
Dermal LOAEL = oral LOAEL x 100/10 x 7/5= 5 x 100/10 x 7/5 = 70 mg/kg bw/day
Correction factor for differences in respiratory volume (rat/general population): 1/1.15
LOAEC = LOAEL x (1/1.15) = 5 x (1/1.15) = 4.3 mg/m3
Dermal LOAEL = oral LOAEL x 100/10 = 5 x 100/10 = 50 mg/kg bw/day
