Exposure of garbage truck drivers and maintenance personnel at a waste handling centre to polycyclic aromatic hydrocarbons derived from diesel exhaust

Increase of urinary concentrations of 8-hydroxy-2′-deoxyguanosine in diesel exhaust emission inspector exposed to polycyclic aromatic hydrocarbons

“…Among several studies that analyzed concentrations of PAHs in particles, one study discovered the lowest concentrations in garbage truck drivers measuring 2.1 ng/m 3 in the summer and 2.7 ng/m 3 in the winter; in maintenance workers, the average concentrations were 0.5 ng/m 3 in the summer and 0.9 ng/m 3 in the winter (Kuusimäki et al 2002); average concentrations of 8.5 ng/m 3 in the summer, 25 ng/m 3 in the winter were reported for bus garage workers (Kuusimäki et al 2003); concentrations in depots measured ranged from 6.2 to 34.7 ng/m 3 (Wheatley and Sadhra 2004); the highest concentrations reportedly found in underground salt mining workers were between 332.1 and 737.2 ng/m 3 (Seidel et al 2002). The indicator often used for carcinogenic PAHs is Bap, not only because of its potency, but also because it is a well-known carcinogen in PAHs mixtures (IARC 1983).…”

“…Currently, occupational research on diesel-related particulate phase PAHs emitted in diesel exhaust mostly focuses on PAHs-absorbed particles less than 10 lm in aerodynamic diameter (PM 10 ) and on PAHs-absorbed particles (Adonis et al 2003;Huang et al 2007;Kuusimäki et al 2002Kuusimäki et al , 2003Seidel et al 2002). Very few studies have analyzed PAHs-absorbed respirable dust and PAHs-absorbed PM 2.5 (See et al 2006;Wheatley and Sadhra 2004).…”

Distribution profile, health risk and elimination of model atmospheric SVOCs associated with a typical municipal garbage compressing station in Guangzhou, South China

“…Therefore, TSP and particle associated SVOCs possibly emitted during the garbage compress process such as PAHs, OCPs, and PAEs were investigated in this work, since the sources of garbage disposed at GCS can be very complex in composition. PAHs may come from road dust and cooking refuse, and diesel exhaust of the compressing machine (Kuusimaki et al, 2002). OCPs exist in food waste as fruits and vegetables.…”

Analysis of Biogenic Volatile Organic Compounds in Air Using a Solid-Phase Extraction-Type Collection Device

“…However, the elution time for Soxhlet extraction is 18 h and the associated low recovery of volatile SVOCs is a disadvantage. For ultrasonic extraction, 20-30 min of ultrasonication is usually used to elute the collected SVOCs, but insufficient recovery is a significant drawback with this method [16,17].…”
