AbstractDespite international regulation, polychlorinated biphenyls (PCBs) are routinely detected at levels threatening human and environmental health. While previous research has emphasized trophic transfer as the principle pathway for PCB accumulation, our study reveals the critical role that non-trophic interactions can play in controlling PCB bioavailability and biomagnification. In a 5-month field experiment manipulating saltmarsh macro-invertebrates, we show that suspension-feeding mussels increase concentrations of total PCBs and toxic dioxin-like coplanars by 11- and 7.5-fold in sediment and 10.5- and 9-fold in cordgrass-grazing crabs relative to no-mussel controls, but do not affect PCB bioaccumulation in algae-grazing crabs. PCB homolog composition and corroborative dietary analyses demonstrate that mussels, as ecosystem engineers, amplify sediment contamination and PCB exposure for this burrowing marsh crab through non-trophic mechanisms. We conclude that these ecosystem engineering activities and other non-trophic interactions may have cascading effects on trophic biomagnification pathways, and therefore exert strong bottom-up control on PCB biomagnification up this coastal food web.

Parameterized Model

A previously developed benthic/pelagic food web bioaccumulation model was parameterized to predict concentrations of nine nonmetabolized polychlorinated biphenyl (PCB) congeners in invertebrates and fish from Lake Ontario. Predicted concentrations were compared with field-measured concentrations to verify the predictability of the model. Overall, 86% of model predictions were within a factor of 2 and 100% of predictions were within a factor of 10 of field-measured concentrations. The parameterized model was used to estimate chemical metabolic rates for 15 PCB, polychlorinated dibenzo-p-dioxin (PCDD), and polychlorinated dibenzo-p-furan (PCDF) congeners that are potentially metabolized. Estimated chemical metabolic rates ranged from 7.5 × 10-3 to 1.0 × 10-7·day-1 and were in general agreement with qualitative studies describing rates of metabolism of these chemicals by aquatic biota. The calibrated model was used to predict concentrations of all 24 PCB, PCDD, and PCDF congeners in invertebrates and fish commonly found in Lake Ontario but for which no field-measured data exist. These concentrations were expressed as the logarithm of the bioaccumulation factor (log BAF). The log BAF's in benthic invertebrates and salmonids ranged from 4.2 to 10.2 and from 5.1 to 11.6, respectively, and were consistent with field-measured BAF's.
