DDT and Agent Orange serve two totally different purposes. DDT is an insecticide. Agent Orange is an herbicide. While DDT is not the best stuff to be breathing in it is far less toxic than the Tetrachlorodibenzodioxin in Agent Orange. If Agent Orange were used - both sprayed out of planes and trucks on the base I lived in - the surrounding vegetation would wither and die as that was its purpose as an herbicide - to destroy the food crops and remove the jungle cover that was hiding the Vietnamese. Not to mention the serious health and birth defects that would soon show up in the base population. I think the Agent Orange stories are just that - a bit of Cold War paranoia.
Regarding my above posting under name RDK. It should have been "Ralph Daniel Killoran". Apologies, I use RDK on the occasional CBC comments but also I am not very good on computers and postings, its always a struggle.
I was born in Trenton and lived in Middleton Park from '53 to '59. I remember watching kids run behind the fogger truck on my street. It was DDT that was used at that time, thinking now how insane that was and what the physical ramifications were from breathing it.
