“…2), whereas the three-ring and four-ring PAH portions were considerably higher in water from big city CQ and CS than from town or counties in Hubei area. Studies (Hong et al 2012;Shen et al 2009;McCready et al 2000;Boonyatumanond et al 2006) found that the composition of 16 priority PAHs in sediments was at similar percentages for five-and six-ring compounds in both agricultural and urban section in rivers, while the four-ring PAHs were considerably higher in surface sediments in urban section. Hong et al (2012) concluded that PAHs in sediment record urbanization effects on environmental changes.…”

Bioavailable concentrations of polycyclic aromatic hydrocarbons (PAHs) were investigated in water of Three Gorges Reservoir (TGR) using semipermeable membrane devices during the period of completely impounding water. ∑PAH concentrations in water of TGR in the period of completely impounding water were 15-381 ng L −1 . ∑PAH concentrations increased from town or counties to big industrialized cities in TGR, indicating urbanization effects on PAH pollution in the water. Tributaries in TGR have a certain contribution of PAH pollution to the mainstream of Yangtze River and their pollution could not be neglected. An obvious decrease of PAH concentration was observed after 175-m water impounding in 2011 in TGR. Several factors may account for this decrease, including execution of comprehensive treatment and management measures in TGR, less rainfall in 2011, and sedimentation effect caused by the dam. Passive sampling method has been successfully applied in the investigation of trace PAH in water of TGR and proved to be a useful and efficient tool for the management and sustainable development of the big reservoir. The results of the study provide valuable information about PAH pollution in the whole reservoir including some tributaries, and the pollution status is dynamically related with human activities. Therefore, PAH could be used as a marker compound or indicator in the network monitoring system to surveil and trace the pollution status in TGR.

“…PAHs originated mainly from anthropogenic sources, such as combustion of fossil fuels and direct release of oil products (Simpson et al, 1996). Anthropogenic PAHs can be introduced to estuaries via urban runoff (McCready et al, 2000), industrial processes (Simpson et al, 1996), vehicle exhausts and spillage of fossil fuel (Pettersen et al, 1997;Wang et al, 1999) in the upper and middle reach areas. Due to their hydrophobic nature (logK ow , 3-8), once PAHs are introduced into the estuarine environment, they were rapidly adsorbed onto suspended particles and hence bottom sediments (Tam et al, 2001;Nogami et al, 2002).…”

“…8 In general, combustion PAH profiles are dominated by relatively high molecular weight compounds with three or more condensed rings, whereas mono-, bi-and tricyclic compounds are predominant in fossil fuel mixtures. 9 The particulate PAHs measured in urban air and in roadway tunnels have been found in the respirable size range. 6,[10][11][12][13] PAHs are regarded as priority pollutants by both the United States Environmental Protection Agency and the European Community.…”

Motor vehicles constitute a significant source of polycyclic aromatic hydrocarbon (PAH) emissions to the atmosphere. Particle-phase priority pollutant PAH concentrations and total suspended particle mass (TSP) were measured in the Lapa bus station and the Americo Simas Tunnel, located in the city of Salvador, Brazil. Separate samples were collected at the bus station at different times of the day, including rush-and non-rushhour periods. The highest concentrations for nearly all 16 priority PAHs measured at the bus station were observed at 18:30 h, with chrysene showing the highest mean value (26.6 ng m 23 ). The highest average PAH concentrations measured in the tunnel were observed for pyrene (79.4 ¡ 11.5 ng m 23 ) followed by fluoranthene (39.0 ¡ 5.2 ng m 23 ) and chrysene (28.0 ¡ 4.17 ng m 23 ). TSP levels reached 423 mg m 23 in the bus station, and values as high as 2 mg m 23 in the tunnel. The measured Salvador tunnel PAH profiles are very similar to the Salvador bus station profiles, and are similar to PAH profiles reported for the Kojouike Tunnel, located in Kurashiki City, Japan, and the Caldecott Tunnel, located in Berkeley, California.
