The first point on the Mercury Myths page incorrectly compares hair levels with blood levels:

"There's even some evidence that human beings are exposed to less mercury today than in the past. Alaska's Public Health Department, for example, reports that when the hair of eight 550-year-old Alaskan mummies was tested for mercury, the results showed levels averaging twice the blood-mercury concentration of today's Alaskans. "

I wonder why they couldn't compare it against the hair of today's Alaskans, wouldn't that be easier than taking blood samples?

Actually I'm kind of glad to see this kind of reaction from the fish corporations because it means that there must be enough of a public concern about the matter. Hopefully the fish corporations also look into muzzling some of the coal and cement firing plants that spew so much mercury into the environment.
