The authors have examined the fit of three alternative, models to PCB concentration data for seven species of Lake Michigan fishes. The best fit model for all seven species indicates that, following rapid decreases through the mid-1980s, PCBs are no longer declining. The authors believe this pattern indicates PCBs are currently originating from global or local pools that are being recycled in the environment. If the current PCB source in Lake Michigan is primarily sediment or fluvial, then this may be an isolated pattern. However, a sizeable atmospheric input would suggest that this problem may be occurring in many systems.
