a Odor thresholds are from Devos et al. (1990), except TMPD-MIB
(Wolkoff and Nielsen, 1993)

b Mouse RD50 values are from Schaper (1993)

c Relative irritancy was calculated using toluene as reference
(VOC RD50 / Toluene RD50)

d 8-h Time-weighted average Threshold Limit Values (ACGIH, 1993)

e TLVs were adjusted following the procedure of Nielsen et al. (1997)

f na = Not available

g TMPD-MIB = 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate
