What about Radon you cannot taste or smell it and can be in your
water,I think,would this do harm? Thanks Sue

Oh crap, MrsD!
 

I've lived in trailers and was sensitive to the formaldehyde. The worst was new trailers. But even in ones that were a number of years old I could still detect it. A burning sensation in my sinuses and such. It would seem to follow that an exposure at long term consistent levels would be a factor but also it makes sense that some people are more sensitive to *any* exposure. Wonder what this means for PN?

I posted just such a question to that author of that article you linked to.
