Stefan,

May I suggest you let well enough alone ?

If one wanted to believe something and they have their mind made up,
you cannot change it.

I could make a case that food is carcenogenic. As research has
shown, every single human that has ever had any form of cancer has
eaten.

Dave,

Welll...... Actually....

One of the most-carcinogenic substances on earth is called aflatoxin. It is a mold or fungus that grows naturally on CORN, while it's still in the cornfield. So watch out for those cornflakes and corndogs!

Also, remember how dangerous pure water is. And breathing, too. (Breathing too much water can kill you!)

By the way, I found out that FERRIC CHLORIDE is used by wastewater treatment plants, added to the water in HUGE quantities. Some of them use thousands of gallons of 50% solution per week. So don't let anyone tell you that Ferric Chloride is a "hazardous chemical". (Of course, AFTER it has the copper in it, from etching, then it's a whole different story, maybe.)

What IS some peoples' "problem", with "man-made chemicals", anyway (as opposed to "natural" substances)? MANKIND is, itself, a part of Nature. So, therefore, EVERYTHING is "natural". i.e. A nuclear plant is no less a part of nature than a beaver dam.

And who allowed the enviro-paranoid-whackos to co-opt the word "organic"? Didn't they ever hear of "organic chemistry"? Plastics and gasoline and coal are as "organic" as it gets!

Hehe,

Tom Gootee
