A comparison of concentrations of polycyclic aromatic compounds detected in dust samples from various regions of the world

Measurement of Organophosphate Pesticides, Organochlorine Pesticides, and Polycyclic Aromatic Hydrocarbons in Household Dust from Two Rural Villages in Nepal

“…The median tPAH value in both Keraghari and Kafaldanda was 14.7 µg/m 2 , above the median value in Azerbaijan but well below the median value in China seen by Naspinski and colleagues [45]. The cPAH levels of 2.06 and 1.89 µg/m 2 in Keraghari and Kafaldanda, respectively were also higher than the levels seen by Naspinski et al [45] in Texas and Azerbaijan but much lower than in China. The samples collected by Naspinski et al [45] in Azerbaijan were obtained from homes near an industrial complex in an area that was an important petrochemical production location for the former Soviet Union, while the samples from China were collected in a location where coal is an important fuel.…”

“…The levels of PAHs in house dust in these Nepali homes were higher than the levels identified by Naspinski and colleagues [45] in homes in Texas, USA and Sumgayit, Azerbaijan, but lower than the levels detected in homes in Shanxi Province, China. Naspinski et al [45] found the median total PAH levels in floor dust samples from Texas, USA, Sumgayit, Azerbaijan and Shanxi Province, China were 1.34, 6.1, and 232 µg/m 2 , respectively, while the median levels of the EPA B2 carcinogenic PAHs (cPAHs) were below the detection limit, 1.0 and 53 µg/m 2 in Texas, Azerbaijan and China, respectively [45]. The median tPAH value in both Keraghari and Kafaldanda was 14.7 µg/m 2 , above the median value in Azerbaijan but well below the median value in China seen by Naspinski and colleagues [45].…”

“…Environmental contaminants may be found in contaminated house dust [44], including PAHs [45] and pesticides [6]. House dust can be an important source of exposures indoors, particularly for children who spend time playing or crawling on the floor and who exhibit frequent hand-to-mouth behavior [6,7,46].…”

“…The sample area was measured and markers were placed to signify the area. To collect the dust, a pre-ashed glass fiber filter cloth (type A/E, Gellman Sciences, Ann Arbor, MI) was saturated with isopropyl alcohol and used to wipe all the dust from the marked area according to the method of Naspinski et al [45]. The cloth was then placed into an aluminum foil pouch inside a Ziploc bag, and transported to the laboratory.…”
