Interesting. But wild salmon do not create PCB's, only man can do that. PCB's are 100% synthetic and all traces are a result of the short time in earth's history that we used them in industrial applications from transformers to lubricants.
So it's only right that we eat them; because only man is buried in leak-proof containers and that's the ONLY way to clean up the damn mess we made with them!
In fact I suggest we MUST eat all contaminated organisms and be buried in better leak-proof containers until such time that the seemingly unrecoverable damage we created with them is reduced to the point that wild salmon register a lower trace level than mass-produced clones.
TIC, sort of.
