Re: Mercury scam?



  Jon,

      Thanks for your note. With evidence that mercury levels in fish has

been

  relatively constant for centuries, we may wonder what caused the concern

  (hysteria?) over mercury levels in seafood (swordfish, tuna, etc.) that

began,

   during the 1960's.  I believe the reason lies in the development of

atomic

  absorption, neutron activation, and other analytical methods that allowed

  for accurate determination of mercury levels so low that they were

previously

  unmeasurable. Researchers seeking funding that would allow them to play

  with these new analytical tools hyped the "problem" of mercury pollution

in

  seafood taking advantage of the tendancy of people to equate detectability

  with hazard.  That, IMHO, is how it happened. Jerry
