“…Fugacity in a medium i was calculated by the equation: f i = C i /Z i , where f i , C i , and Z i is fugacity, concentration, and fugacity capacity, respectively. To calculate Z values, temperature dependent vapor pressure and Henry's law constant were estimated following [43] and [44], respectively. Among the various forms of carbons as effective sorbents, only organic carbon (OC) was taken into account in the calculation of fugacities [42].…”

Interrelationships between pyrogenic polycyclic aromatic hydrocarbons (PAHs) were assessed in air, soil, water, sediment, and tree leaves by using multi-media monitoring data. Concurrent concentration measurements were taken bimonthly for a year for the multi-media at urban and suburban sites. PAH level correlations between air and other media were observed at the urban site but were less clear at the suburban site. Considering a closer PAHs distribution/fate characteristics to soil than suspended solids, contamination in sediment seemed to be governed primarily by that in soil. The partitioning of PAHs in waters could be better accounted for by sorption onto black carbon and dissolved organic carbon.

A paired whole-lake experiment was conducted on two remote, atmospherically driven lakes in the Experimental Lakes Area (ELA) to examine the stresses of trophic condition on air-water exchange and settling fluxes of polychlorinated biphenyls (PCBs). Lake 227 (L227) and Lake 110 (L110) are similar in volume, surface area, and watershed area but differ significantly in trophic status. The two lakes have similar access to atmospheric PCBs but eutrophic L227 may exhibit enhanced air to water exchange due to greater biotic uptake of dissolved PCBs. ). Greater ⌺PCB settling fluxes in L227 vs. L110 coupled with similar dissolved concentrations after June supports the hypothesis that air-water exchange supports the water column PCB concentrations. Surprisingly, ⌺PCB fugacity gradients in both lakes indicated that net volatilization dominated during the entire ice-free period, requiring another source. A ⌺PCB mass budget in the epilimnion of each lake over the stratified period showed that the major PCB losses were due to settling and volatilization. ⌺PCB settling losses were 2.4 times greater in L227 than in L110 due to higher settling particle fluxes. The mass budgets suggest that the major PCB input to these remote lakes is from the watershed. Our results indicate the intimate environmental linkage between atmospheric, land, and aquatic PCB reservoirs.Two of the greatest problems affecting many freshwater lakes are eutrophication and contamination of fish with organochlorines, such as polychlorinated biphenyls (PCBs). For example, there are active programs to reduce both nutrient levels and PCB concentrations in several of the Great Lakes. Previous studies suggest there may be important interactions between PCB concentrations and trophic condition (Larsson et al. 1992;Taylor et al. 1991). An understanding of the interactions between trophic condition and PCB concentrations is essential for effective management.

“…Then, the slope of the log Cvol vs 1/T relationship should be the slope of the log H vs 1/T relationship. The slopes of the plot of log H vs 1/T for tetrato heptachlorobiphenyls have been found to range from -3900 to -3200 (16)(17)(18).…”

The source and environmental behavior of dioxin-like polychlorinated biphenyls (PCBs) together with other PCBs and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDDs/PCDFs) were evaluated based on analysis of variations in their atmospheric concentrations in Yokohama, Japan. Potential factors responsible for variations in the atmospheric concentrations of the congeners were investigated by principal component analysis and multiple regression analysis of the data. Two major variations were seen: one had strong temperature dependence, while the other had no significant temperature dependence. A possible explanation for this difference is that the former is related to congeners released by volatilization (e.g., volatilization from commercial PCB products and past polluted environments), while the latter is related to congeners emitted from thermal processes. The relative contributions of dioxin-like PCBs released by volatilization and those emitted from thermal processes were estimated based on the temperature dependence of the atmospheric concentrations. The results suggest that both dioxin-like PCBs emitted from thermal processes and those released by volatilization are significant sources of air pollution in this area in terms of the toxic equivalent (TEQ) for dioxin-like PCBs. We demonstrated that the present approach based on variations in atmospheric concentrations can be useful in providing a qualitative as well as quantitative understanding of source information.
