“…A correlation of log ⌺PCB with inverse average daily temperature (ЊK) resulted in r 2 ϭ 0.52 (P ϭ 0.00034). The slope of the log C vs. 1/T line was Ϫ5,140, similar to slopes found by Hoff et al (1992) and Hillery et al (1997).…”

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.

“…Likewise significantly lower ATP values were found at LV than at CC and SK (P b 0.0008) with SK values over 6 times higher (Table 2), with only pentachloroanisole correlated (negatively) ( Table 3). Pentachloroanisole, the main degradation product of both pentacholorphenol and the herbicide/fungicide pentachloronitrobenzene, is a stable congener that bioaccumulates and transports atmospherically (Hoff et al, 1992). It was also positively correlated with VTG and T3 (P b 0.05; Table 6).…”
