"It seems to me that if you want to reduce the Hg content of fish, you
are making the assumption that it has increased recently and that the Hg
content of fish is amenable to human intervention. So, how does mercury
get into marine fish fish?"
Mercury occurs in the substrate off the west coast of Vancouver Island,
British Columbia, and is found in the halibut harvested from that area.
