PCB's in Alaskan lakes

Saw an article in our local newpaper (Skagit Valley Herald) today on sockeye bringing PCB pollution from the Pacific into remote Alaskan lakes. There have been several remote lakes that have been found to have some rather high levels of PCB's and the only explanation is the sockeye have been bringing them in from the Pacific on their spawning runs and then the PCB's are being deposited in the lake bottoms as they die and decompose.

It makes me wonder how many of the sockeye that are sold each year from the lucrative commercial sockeye fishery are tainted with PCB's. I also wonder what the recommended maximum sockeye consumption should be to avoid ingesting too much PCB.

Definitely food for thought.
