Last Friday's edition of Rachel's Environmental and Health Weekly was
devoted to the question of mercury contamination of food, specifically
fish.  Unfortunately, I have already deleted it, but it will eventually be
listed in the Rachel's List archive at http://www.monitor.net/rachel/
The bottom line of the article was that eating more than 7 ounces of fish
per week will cause one to exceed the EPA's recommendations for mercury
intake.  A good argument can be made that the EPA guidelines are too high.
Also, the form of mercury found is fish is the most toxic  form.
