“…Unlike lower-brominated PBDEs, no correlation was found between P 7PCBs and either SPM or POM, which agrees well with previous findings by Chevreuil and Granier (1991). This discrepancy between PCB and PBDE behavior remains unexplained, but it may be related to PCB sources in the Seine watershed, which are mainly associated to a legacy stock.…”

“…During high-flow periods, SPM levels increased by [700% (8 to 64 mg l -1 ) compared with lowflow periods, whereas the particle-bound PCB fraction increased by only 58%. Accordingly, during low-flow periods, the median PCB and PBDE levels in the particulate phase (respectively, 32 and 80 ng g -1 ) was, respectively, approximately 1.4 and 2.1 times greater than that during flood periods (23 and 39 ng g -1 , respectively), suggesting an input of less contaminated suspended sediment or a decrease of the SPM sorption capacity as has been previously observed in the Seine River (Chevreuil and Granier 1991;Teil et al 1998). On the whole, the PBDE/ PCB partitioning is strongly dependent on the concentration and adsorption capacity of SPM (Voice et al 1983) Thus, to improve the characterization PCB and PBDE distribution, the partitioning coefficient between the particulate and dissolved phase (Kp [l kg -1 ]) was calculated.…”

The temporal dynamics of polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) were investigated in a heavily urbanized river (Seine River, Paris, France) from November 2009 to May 2010. Pollutant concentrations were in the range of 0.2 to 3.8 ng l(-1) (median 1.1) and 0.4 to 3.6 ng l(-1) (median 1.1) for ∑ tri-deca BDEs and ∑ 7PCBs, respectively. In addition, for both PBDEs and PCBs, the partitioning between the particulate and dissolved phases was investigated. Due to their low water solubility, PBDEs were mainly (>70%) bound to particles. In contrast, only 54% of ∑ 7PCBs occurred in the particulate phase, and their partitioning was influenced by the degree of chlorination. During the sampling period, PBDE/PCB fluxes were quite similar and ranged from 3 to 128 and from 6 to 125 g day(-1), respectively. The annual mass flow of PBDEs and PCBs was estimated to 10 kg for both. Contrary to PCBs and BDE-209, the temporal evolution of ∑ tri-hepta BDEs was related to particulate organic matter content, which is controlled by river flow variations. This suggests that they exhibit different sources or behavior in the Seine River.

“…4). This high level of PCBs in this river water may also be explained partly by the leaching of PCBs from urban activities at Durban as was demonstrated by Chevreuil and Granier who showed that the main cause of high levels of PCB in the basin of river Seine in France was leaching (Chevreuil and Granier 1985;Kim et al 2007). …”

The Umgeni River is one of the main sources of water in KwaZulu-Natal, South Africa; however; there is currently a lack of information on the presence and distribution of polychlorinated biphenyls (PCBs) in its sediment, sediment pore water and surface water. This study aims to determine the occurrence and significance of selected PCBs in the surface water, sediment pore water and surface sediment samples from the Umgeni River. Liquid-liquid and soxhlet extractions were used for water or pore water, and sediments, respectively. Extracts were cleaned up using a florisil column and analysed by gas chromatography-mass spectrometry. The total concentrations of eight polychlorinated biphenyls were 6.91-21.69 ng/mL, 40.67-252.30 ng/mL and 102.60-427.80 ng/g (dry weight), in unfiltered surface water, unfiltered sediment pore water and surface sediments, respectively. The percentage contributions of various matrices were 4, 36 and 60 % for unfiltered surface water, unfiltered pore water and sediment, respectively. The highest concentrations of PCBs were found in water, pore water and sediment collected from sampling sites close to the Northern Wastewater Treatment Works. The highest chlorinated biphenyl, PCB 180, was the most abundant at almost all sampling sites. To our knowledge, this is the first report on occurrence of polychlorinated biphenyls in the Umgeni River water, pore water and sediment system and our results provide valuable information regarding the partitioning of the PCBs between the water and sediment systems as well as the organic chemical quality of the water.

“…The importance of snowmelt in enhancing PCB riverine transport during the spring hydrologic flush has been speculated by Quemerais et al [30], who found that snow‐melt runoff correlated with a pronounced increase in dissolved‐phase PCB concentrations in tributaries of the St. Lawrence River (Canada) in the spring hydrograph. Studies by Chevreuil and Granier [31] also showed a similar seasonal hydrologic dependence of PCB concentrations in the River Seine (France) and further determined that PCB concentration maxima slightly preceded the hydrograph peak during storm flow for the dissolved phase especially. Alternatively, in the Eman River (Sweden), it has been shown that PCB concentrations can be inversely related to river discharge in spring where snow melt is thought to dilute riverine PCB concentrations [32].…”

Riverine fluxes of several pesticides and other organic contaminants from above the fall line of the Susquehanna River basin to northern Chesapeake Bay, USA, were quantified in 1994. Base flow and storm flow samples collected at the fall line of the river from February to December 1994 were analyzed for both dissolved and particulate phase contaminants. Measured concentrations of the organonitrogen and organophosphorus pesticides varied mainly in response to the timing of their application to agricultural fields. Conversely, the concentrations of the more particle‐sorptive contaminants such as polychlorinated biphenyls (PCBs), organochlorine (OC) insecticides, and polycyclic aromatic hydrocarbons (PAHs) were more directly correlated with river flow throughout the year. Annual fluxes were almost entirely in the dissolved phase for the organonitrogen and organophosphorus pesticides, distributed between the dissolved and particulate phases for the PCBs and OC insecticides, and primarily in the particulate phase for the PAHs.
