The temporal variability of the profile of carcinogenic polycyclic aromatic hydrocarbons in urban air: a study in a medium traffic area in Rome, 1993–1998

Genotoxic and mutagenic activity of environmental air samples in Flanders, Belgium

“…In winter, the individual PAH concentrations were higher (except for Ace) than in summer. Similar seasonal trends were also observed in previous studies [24][25][26]. Higher PAH concentrations in winter are due to the contribution of domestic heating and to the specific meteorological conditions, i.e.…”

“…With average concentrations of 1.4 ng/m³ (0.1-5.3) in winter and 0.1 ng/m³ (0.02-0.1) in summer, B(a)p levels in our study were among the lowest values reported in Europe. In Naples for instance, average concentrations were 2.67 ng/m³ (0.09-12.18) during winter and 1.09 ng/m³ (0.03-4.02) in summer [24], and concentrations comparable to those were found in Prague (Czech) [32] Rome (Italy) [24], Thessaloniki (Grece) [27] and Teplice (Czech) [32].…”

“…In many studies B[a]p has been used as indicator compound for PAH exposure because of its strong carcinogenicity and close correlation with other PAHs [31,24]. With average concentrations of 1.4 ng/m³ (0.1-5.3) in winter and 0.1 ng/m³ (0.02-0.1) in summer, B(a)p levels in our study were among the lowest values reported in Europe.…”

Vertical Distribution and Potential Risk of Particulate Polycyclic Aromatic Hydrocarbons in High Buildings of Bangkok, Thailand

“…Several studies suggested that B[e]P can be used as an indicator of PAH pollutions due to its high stability in atmospheric environment Menichini et al, 1999;Wan et al, 2006). In this study, B[e]P was also selected as a profile index because of its relative stability in the atmosphere, which ensures that the differences in PAH profile between two sites were the result of traffic and not caused by atmospheric chemical reaction.…”

Molecular composition and compound-specific stable carbon isotope ratio of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere in suburban areas

“…In addition, there were weeds, approximately 30 cm high, growing between S1 and S2. The gas phase was not collected because hazardous carcinogenic PAHs are mostly associated with particulate matter (Caricchia et al, 1999;Menichini et al, 1999). Suspended particulate matter was collected by pumping air through a quartz fiber filter (Pallflex 2500QAT-UP) which was preheated at 550°C for 6 h. Flow rates (typically 0.5 m 3 min -1 ) were monitored at the start and end of sampling period with a calibrated bulb meter.…”
