Table 1. Effect of handling time on estimated intake when concentrations in thermal paper are low.

	K = 1072	K = 1838	K = 21522
AF = 2.3%	51.1 ± 0.80	87.6 ± 1.37	1026.2 ± 16.09
AF = 8.6%	191.1 ± 3.00	327.7 ± 5.14	3836.9 ± 60.18
AF = 27%	600.0 ± 9.41	1028.8 ± 16.14	12046.1 ± 188.94

Estimated exposure calculated using Eq 1, a single handling event, and thermal paper concentrations of 211 μg/g, the geometric mean reported previously by Liao & Kannan [25]. Scaling factors to account for different handling characteristics were not considered (see Eq 1).
