I also encourage you to read some of the articles cited at junkscience. Some of their points are misinterpreted and ignore a lot of valid research that contradicts their carefully selected papers (checkout their disclaimer on the DDT death watch, LOL). The truth is we do not fully understand the effects of DDT but there are some pretty alarming correlates with DDT use. To ignore them, well, is ignorant.
Again let me state I am all for responsible use of DDT- though those who claim DDT is completely safe and harmless are doing a disservice by masking the facts.
I lived in a DDT environment in he Canal Zone. The DDT truck used to come around at dinner time and spray all over the houses and on to the food.
No one who lived in the Canal Zone has died of DDT poisoning. Studies continue on us today.
