Table 1 Geometric means (and geometric standard deviations) of PAH measures in personal air samples (ng/m3) collected over the work hours (A) and PAH levels in dermal wipes (μg/wipe) collected before and after work (B)
From: Short-term markers of DNA damage among roofers who work with hot asphalt
A. Airborne exposure measurements (n = 40) | ||
 Naphthalene (ng/m3, XAD) | 361.4 (2.9) | |
 Pyrene (ng/m3, XAD) | 2.3 (7.5) | |
 Naphthalene (ng/m3, FLT) | 0.78 (2.7) | |
