“…As discussed for Station 84 results, a strong inverse dependence of partitioning of PCBs with sediments on the aqueous activity coefficient is expected from laboratory results (Karickhoff et al, 1979;Chiou et al, 1983;Gschwend and Wu, 1985) and has been observed in water column measurements reported here and in other environments (Bopp, 1979, Pavlou andDexter, 1979;Tanabe and Tatsukawa, 1983). In contrast, it should be noted that (Bopp, 1979;Bopp et al, 1981). There were only slight changes in peak ratios with depth, and those were directly attributable to changes in the up-river PCB source which were well documented.…”

“…Recent studies have emphasized this fact and have made important progress in the use of PCBs as model HOC (Bopp, 1979;Bopp et al, 1981;Tanabe et al, 1982;Gschwend and Wu, 1985). Progress has also been made in obtaining chlorobiphenyl identifications (Duinker and Hillebrand, 1983;Mullin et al, 1984) and physical chemical property data (Bruggeman et al, 1982;Rapaport and Eisenreich., 1984;Bidleman, 1984;Burkhard et al, 1985).…”

“…Field measurements of unresolved isomer groups of chlorobiphenyls have provided tests for equilibrium partitioning between seawater and suspended particulates (Dexter and Pavlou, 1978a) and between water and suspended sediments in the Hudson River (Bopp, 1979;Bopp et al, 1981). The studies of…”

“…PCBs and other stable chlorinated hydrocarbons may potentially provide valuable tracers for the study of deep ocean biogeochemical processes (Farrington and Westall, 1986) and have been actively used as model HOC in the study of partitioning and transport processes in coastal (Dexter and Pavlou, 1978a), riverine (Bopp, 1979;Bopp et al, 1981), and lacustrine environments Eadie et al, 1983;Baker et al, 1985).…”

“…The wide range of solubilities of individual chlorobiphenyls Bruggeman et al, 1982) and their slow rates of chemical or biological degradation (NAS, 1979) make PCBs especially valuable tracers for studying sorption processes under natural field conditions. PCB measurements in the field have been used to study particle-seawater partitioning of HOC (Dexter and Pavlow, 1978a), sediment transport in the Hudson River (Bopp, 1979;Bopp et al, 1981); and the associations and transport of PCBs with particles in the Great Lakes Eadie et al, 1983;Baker et al, 1985) and the Pacific Ocean (Tanabe and Tatsukawa, 1983). The production and regulatory histories of PCBs, and estimates of their sources and transport pathways have been reviewed (Nisbet and Sarofim, 1972;NAS, 1979).…”

WITHDRAWN AD -sT~i~Bñ~c i~tZ4-2-ABSTRACT Polychlorinated biphenyls (PCBs) were used as model hydrophobic organic compounds (HOC) to study physical-chemical processes which affect the speciation and fate of HOC in coastal environments. The focus of this study is on the sorption of PCBs with colloidal organic matter in seawater, and the influence of this process on the distribution of PCBs in coastal sediments. Laboratory and field experiments were used to make quantitative estimates of PCB-organic matter sorption, and to test predictions of three-phase equilibrium models.A static headspace partitioning method was developed to measure the sorption of several individual chlorobiphenyls with colloidal organic matter enriched from coastal seawater by hollow fiber ultrafiltration. This technique directly measured the dissolved phase fugacity of PCBs in experimental bottles, and avoided uncertain separation techniques often used in isolating various chemical phases. Colloidal organic carbon normalized partition coefficients (Koc) were determined from linear sorption isotherms, and increased from 1.9 x 10' (L/Kg) for 2,4'-dichlorobiphenyl to 3.5 x 10 s for 2,2',3,4,5'-pentachlorobiphenyl. Sorption tended to increase with increasing octanol-water partition coefficients (Kow) of the sorbate, and values of Koc were within a range of those reported in other experimental sorption studies with sediments and dissolved humic substances. Experimental partitioning results support the hypothesis that HOC-organic colloid sorption is similar to HOC sorption by sediment organic matter.PCBs were measured in the interstitial waters and sediments of three box cores obtained from New Bedford Harbor and Buzzards Bay, Massachusetts. The three sites studied had a wide range of sediment PCB concentrations, and reducing conditions provided environments containing high concentrations of colloidal organic matter. Dissolved organic carbon (DOC) and total sediment organic carbon (TOC) were measured in two cores to test the role of organic matter on the observed partitioning of PCBs. PCB concentrations, particularly those of less soluble chlorobiphenyls, were highly elevated in interstitial waters compared to water column concentrations at all three sites. The measured apparent distribution coefficients (K'd) of individual chlorobiphenyls did not increase with hydrophobicity (Kow) and indicate that a large fraction of PCBs in interstitial waters must be sorbed to organic colloids. A three-phase equilibrium sorption model, in which dissolved PCBs are in a dynamic equilibrium with colloidal and sediment organic matter, accounts for many aspects of the field data. There is good agreement of observed partitioning at New Bedford Station 67 and Buzzards Bay Station M with model calculations based on predictions derived from laboratory experiments of HOC sorption with sediments and organic colloids, but model calculations underpredict K'd at Station 84 in New Bedford Harbor.-3-The sediment-interstitial water results were contrasted with a study of PCB pa...

This study summarizes the relevant information regarding the spatial distribution of polychlorinated biphenyls (PCBs) in various environmental (e. g., soil, sediment, air, water) and biological (e. g., fish, mussel, adipose tissue, milk) media in Turkey. The information sources used for this purpose, in addition to the scientific literature, were; official import records, governmental reports on monitoring of organochlorines, and reports prepared by international organizations. PCBs were never produced in Turkey; however they were imported and used within equipment or otherwise. The number of studies conducted on the topic is increasing significantly throughout the years and especially in the last decade. Evidence of PCB pollution was compared with the available background monitoring results from the region and other parts of the world, as well as relevant legislative standards. Overall, the presence of a number of important local PCB contamination sources is indicated as a result of this assessment.
