(1) Do you have a reference to the article; Id be interested in pursuing
this topic as I don't want to get it wrong.
(2) I have always understood that the levels of mercury in the oceans had
risen sharply this century and a prime source was from coal burning power
plants. See these two summaries of the situation
http://www.ems.org/mercury/power_plants.html
and
http://www.ems.org/mercury/fish.html
The fact remains that the Australian Fisheries Industry Development
Council recommends a limit of 400g a week of oily fish. Follow this link
to the .pdf version of their colour booklet containing this recommendation.

That all adds up to a pretty good argument, but Im open to contrary views.
