“…This profile parallels the decline in the production and use of technical PCBs in China, in agreement with several previous findings regarding the trend of PCB residuals in the aquatic ecosystem in the past 15-20 years (22,23).…”

Water, sediment, and aquatic species including plankton, fish, and turtles were collected from a small lake in Beijing, which receives effluent discharged from a large sewage treatment plant (STP). The samples were examined to investigate polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) releases from a STP and their distributions in the lake. The accumulations of ∑ 12 -PBDEs and BDE-209 in the sediment were 62.3 and 1150 ng/ cm 2 , respectively, while that of ∑PCBs was 99.3 ng/cm 2 . BDE-209 was detected in more than 50% of the aquatic species. A strong linear correlation (R 2 ) 0.92) was found between ∑ 12 PBDEs and ∑PCBs levels in aquatic species but not in sediments. The different PBDE congener profiles in sediments and biota samples suggest metabolic debromination in the sampled fish. Bioaccumulations of PBDEs and PCBs were found in aquatic species. The logarithm bioaccumulation factor (BAF) decreases with the number of bromines in PBDEs molecules, while the log BAF versus the number of chlorines in PCBs appears to be parabolic. Biomagnifications of these compounds were not obvious in the food web by analysis of the relationship between ∑ 12 PBDEs or ∑PCBs levels and the trophic level of aquatic biota species.

“…However, volatilization of PCB from soil, land lls, road oil and other sources can result in measurable atmospheric pollution. It was reported that atmospheric deposition was thought to be responsible for 58-90% of Lake Superior and Michigan's PCB burden (Eisenreich et al, 1981;Jeremiason et al, 1994). Various lines of evidence indicated that polynuclear aromatic hydrocarbons (PAHs) concentrations in vegetation can be used as an indication of atmospheric deposition directly on the above-ground plant portions, and that uptake and translocation of soil-bound PAHs were negligible.…”

Polychlorinated biphenyls (PCBs) are classi ed as priority pollutants by environmental agencies. A eld investigation on polychlorinated biphenyls movement and retention in paddy eld was conducted during 1993, 1997 and 1999 at the WenTai area. Soil, air and rice samples were analyzed. PCB concentrations in the soil showed a reducing trend with respect to time and depth. Most of the di-, tri-, and tetra-chlorinated PCB congeners showed signi cant decreases during the period, while the more highly chlorinated PCBs were more persistent in soil. The results of eld investigation data showed that even though 6 years the PCB concentrations in two elds were far from reaching uniform. In addition, rice grown in the eld appeared somewhat contamination by PCBs, but it was not likely subjected to concentrating PCBs from contaminated soil signi cantly. It was shown that the PCB concentrations in rice samples were not directly proportional to their concentrations in soil. Principal component analysis was performed with the standardized relative abundance of PCBs in the samples. All these observations indicated that the pattern of PCBs in soil cannot be considered to re ect the original pollution source.

“…The atmosphere serves as an important pathway for global transport of PCBs. Particle deposition (Zannetti, 1990;Noll et al, 1990), gaseous air-water exchange (Hornbuckle et al, , 1995Jeremiason et al, 1994;Zhang et al, 1999) and wet deposition via rain and snow (Franz 1994;Poster and Baker, 1996) are the major atmospheric removal mechanisms for PCBs.…”

“…Mass balance is another approach used to determine the flux magnitude and direction. This approach is based on determining the relative inputs and outputs of a chemical from a water body (Baker et al, 1993;Strachan and Eisenreich, 1989;Jeremiason et al, 1994). The third method of determining the dry deposition flux is direct measurement with surrogate surfaces.…”

“…Murphy et al (1981) employed filters that were wetted with propane and butanediols as a collection surface. PCBs enter the atmosphere from incinerators, landfills, or soil and air/water exchange (Murphy et al, 1981(Murphy et al, , 1985Hornbuckle et al, 1994Hornbuckle et al, , 1995Jeremiason et al, 1994;Zhang et al, 1999;Franz, 1994;Poster and Baker, 1996;Hsu et al, 2003;Garcia-Alonso and Perez-Pastor, 2003). Since there are some important PCB sources around Chicago, the atmospheric concentrations of PCBs are higher there than many other urban areas (Tasdemir et al, 2004;Green et al, 2000;Simcik et al, 1998;Cotham and Bidleman, 1995).…”

The interest in atmospheric deposition by the scientific community has increased a great deal over the past several years because of its significant contribution to the pollution budget of many natural waters. Dry deposition is an effective removal mechanism for polychlorinated biphenyls (PCBs) from the atmosphere. This study focuses on the understanding of the particulate dry deposition of PCBs in urban areas. In this paper, 43 chromatographic PCB congener peaks which represent 50 individual or coeluting congeners were evaluated.The PCB dry deposition fluxes were measured using a smooth, greased, knife-edge surrogate surface holding greased Mylar strips in Chicago, IL. The average PCB dry deposition flux measured (190780 ng m À2 day À1 ) was similar to those measured in other urban areas. Ambient air samples were also collected simultaneously with flux samples. The average apparent dry deposition velocity, calculated by dividing the fluxes to the particle phase concentrations was 5.272.9 cm s À1 . This value is in good agreement with the values calculated using similar techniques.
