“…During the summer, when photochemical activity is expected to be highest, levels of quinones should be generally higher than during colder seasons; however, as a result of lower inversion layer during the winter, at sites with no significant photochemical activity, quinone levels would be expected to be higher, especially those associated with the particle-phase. Previous studies evaluating the effect of temperature on particle-phase concentrations Yeo et al 2003) found a negative correlation between temperature and particle-phase PAH concentrations for primary emitted PAHs; similar results may be expected for quinones.…”

“…Atmospheric concentrations of quinones were low for rural areas, especially those located north of the LA Basin. Concentration differences between urban and rural areas have been previously reported (Albinet et al 2007;Yeo et al 2003); in general, the higher concentrations observed in urban areas suggested an important contribution of primary sources of both quinones and parent compounds in these areas. Except for 9,10-AQ, the annual average concentrations varied among the sites, indicating a spatial variability that has to be taken in account when conducting human exposure studies.…”

Quinones are reactive organic compounds known to initiate reactions associated with a host of toxicological events. Their presence in different atmospheres has been demonstrated although their sources remain uncertain. As a result of their reactivity and instability during chemical analysis, only a limited number of studies have reported on atmospheric concentrations of quinones in ambient air. Furthermore, besides the limited information on quinones associated with particulate matter, no previous studies have quantified vapor-phase quinones. We report vapor-and particle-phase concentrations of 1,2-and 1,4-naphthoquinones (1,2-NQ, 1,4-NQ), 9,10-phenanthraquinone (9,10-PQ), and 9,10-anthraquinone (9,10-AQ), measured over a 5-year period in Southern California. The results showed that vapor-phase concentrations of the target quinones were in general higher than those in the particle-phase. Vaporphase concentrations ranged from 80 pg/m 3 for the AQ to 1747 pg/m 3 for the 1,4-NQ, and the particle-phase concentrations between 13 pg/m 3 for the 1,2-NQ and 250 pg/m 3 for 9,10-AQ. The target quinones were found to be distributed between vapor-and particle-phase, with the exception of 9,10-PQ found only in the particle-phase. The differences observed in the concentrations among sites and seasons suggest different source contributions; source sites were dominated by primary sources, while downwind locations showed a high contribution from photochemical activity.

“…The substantial increase in PCB concentrations in cold weather in the industrial area was presumably caused by the light winds, the low effective photochemical degradation and the presence of fresh emissions. Higher concentrations of PCBs in atmospheric particles during cold period have also been observed by other investigators due to the lower ambient temperature as well as to the increase of suspended particles in the atmosphere (Brunciak et al 2001;Yeo et al 2003). The relationship of RPCB concentrations with air pollutants and meteorological parameters such as temperature, rainfall and wind speed is shown in Table 2.…”

“…High concentrations, although with a decreasing trend in the past, had been reported for Paris, France (Granier and Chevreuil 1991;Biterna and Voutsa 2005). High concentrations of particle phase PCBs had been reported for a rural area in southern Taiwan (the particle phase represents 56.4% of the mean total concentration of 2,500 pg m -3 , Chen et al 1996), whereas relatively low concentrations were found in rural atmosphere of South Korea (6.56 pg m -3 ) (Yeo et al 2003). To assess the extent of how the concentrations at the industrial area compare with other locations, congener-specific concentration data (arithmetic means) reported for other locations were compiled.…”

Polychlorinated Biphenyls (PCBs) in PM10 Surrounding a Chemical Industrial Zone in Shanghai, China

In order to gain comprehensive understanding of status, properties and sources of PCBs pollution at an industrial area in Shanghai, PM10 were collected during the period November 2004-September 2005. The results showed that the mean value of total PCBs in the industrial area was 2,017.22 pg m(-3). Three dioxin-like PCB congeners had a mean value of TEQ of 0.24 pg-TEQ m(-3). The concentrations of PCBs at all sites were higher in colder months than in warmer months. SigmaPCB concentrations were correlated positively with SO2, NO2 and OCPs, while negatively with polycyclic aromatic hydrocarbons (PAHs), ambient temperature, rainfall and wind speed. It could be concluded that the area had been contaminated by PCBs from a local source.

“…Despite restrictive legislation in effect since the 1970s in the United States and Europe and since 1993 in Russia (Breivik et al 2004), PCBs persist in the environment. Recently, their presence was reported in different parts of the world in the Baltic Sea area (Europe [Falandysz et al 2004]), in the Chesapeake Bay (USA [Brunciak et al 2001]), and in South Korea (Asia [Yeo et al 2003]). In addition, PCBs might be formed in incinerators, either by de novo synthesis from organic carbon and chlorinated precursors or arising from undestroyed congeners initially present (Van Gerven et al 2004).…”

Polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), and phthalates were investigated from July 2009 to April 2010 in three fish species from the Orge river, which flows in a densely populated area of Ile-de-France. In two Cyprinidae (roach and chub) and one Percidae (perch), muscle contents in increasing order ranged as follows: 12-18 ng g(-1) dw for PBDEs (Σtri-hepta), 120-170 ng g(-1) dw for PCBs (Σ7), and 2,250-5,125 ng g(-1) dw for phthalates (Σ7). No variation was observed between contaminant contents and lipid levels. No biomagnification was found according to the trophic level for PBDEs and PCBs, whereas for phthalates the highest contents were found in perch. Seasonal variations were observed with the lowest PBDE and PCB contents occurring in July after spawning in roach and perch (p < 0.001). PBDE content followed a decreasing trend-gonad > liver > muscle-whatever the period. For PCBs, gonad and liver contents remained greater than that of muscle (p < 0.05). Our results indicate a preferential accumulation of halogenated compounds in gonad and liver outside the reproduction period. Bioaccumulation factors for PCBs in muscle were significantly correlated to their chlorination degree in perch (p < 0.01) and roach (p < 0.01). In roach, that correlation slope was by decreasing importance order as follows: gonad > liver > muscle. The biota-sediment accumulation factors varied from 0.1 to 29.2, from 1.6 to 4.8, and from 1 to 123.5 for PBDEs, PCBs, and phthalates, respectively. These results contribute to document the use of freshwater fish as bioindicators of river quality.
