The point is that the salmon spend their lives elsewhere and fish tend to concentrate heavy metals in their livers especially, but in their tissues and other organs. Spawning concentrates the fish, runoff would carry the mercury compounds downriver...

It may not apply here, and may just be a quirk of global wind circulation (from Chinese or Russian power plants)--who knows. My bet is that if more grant money leads to more studies with similar results, there will be yet another push to use the information to shut down industry in the US, and not elsewhere.

Yeah. I suspect the decaying fleet at Vladivostok and the usual culprits of completely unrestrained pollutant dumping by most of the pac rim nations.

We could, maybe, harness the power of ecoactivism and graft some ecotards together to form filters for the waters as they pass back down stream.

It’s not like they have a nervous system or are evolved enough to self aware, so they’d hardly know they were supposed to be suffering.
