Thanks Mrs. D.

I agree on this .... Here is an interesting article on xenoestrogens in the environment...and I think these are much more alarming.

I read an interesting article related to our conversation, that speaks about many environmental substances: New Thinking on Neurodevelopment

Snip...

The notion that some substances in the environment can damage the nervous system has an ancient history. The neurotoxicity of lead was recognized more than 2,000 years ago by the Greek physician Dioscerides, who wrote, “Lead makes the mind give way.” In the intervening millennia many other substances have been added to the list of known or suspected neurotoxicants. Despite this accumulation of knowledge, there is still much that isn’t understood about how neurotoxicants affect the developing brain, especially the effects of low-dose exposures. Today researchers are taking a hard look at low-dose exposures in utero and during childhood to unravel some of the mysteries of impaired neurodevelopment.

I highly recommend it, it's an interesting read.
