The total fluxes of ∑16PAH due to dermal contact (0.2–50 ng day–1 of BaPeq, out of which ∼99% was attributed to the uptake of gaseous PAHs) were comparable to or larger than those via inhalation (2.8–26 ng day–1 of BaPeq) (Table 2), similar to what was reported previously.(24) Furthermore, light and thin cloths are expected to provide negligible resistance to the transport of gaseous organic compounds from air to skin,(22) further emphasizing the possibility of dermal exposure in warmer months. Uncertainty analyses indicated that the transdermal permeability coefficient (kp_g) had the greatest contribution (>83%) to the total variance of transdermal fluxes. Apparently, additional research is warranted because there are limited measured values of kp_g available in the literature.
