see my above post to tcodi.

I have to speak out on DDT's behalf. DDT is perhaps the safest and most effective pesticide ever used. It is so safe, that for many years, it was sprayed directly onto people to kill lice as well as over large residential areas to kill mosquitos. Nobody was ever harmed by it. Do you hear of malaria much anymore? DDT is still used in every other country but the US and is responsible for the reduced instances of malaria. Many jungle countries spray the jungle with DDT to kill mosquitos with little harm to other species. There are 2 reasons DDT was outlawed, it doesn't biodegrade rapidly, and it weakened the egg shells of birds. It was not outlawed because it was poisonous or harmful to humans.

Back in the late fifties the scientists were predicting that the next ice age was just around the corner, now it's global warming. What happened to the ice age that was supposedly imminent?

Question:

Can you run lead in a non-emissions (no convertor or sensors or egr) engine with heads that have the hardened seats?

Is there any benefit if you can?

Streeter:

1. yes
2. no, if its a street engine

thanks for clearing that up.

The DDT scare was long ago proven to be based on junk science.

The following article only scratches the surface of the fraud perpetrated by the National Audubon Society (scrill down about 10 paragraphs) ---

Thanks for shedding some light on this topic. (BTW, I'm sure you meant to say it was NOT "poisonous to humans" in your post.

ha I ate a lot of lead paint when i was a kid and i feel fine but i can not remember much ?.........hum ok lead mite not be to good for humans

Hemihitter70, that is a very interesting article about DDT. I was not aware of the pre-DDT decline of hawks and eagles. Still many of these issues are caused by over use and unthinking policies. I am just trying to calibrate on a sensible analysis of what you are saying relative to two instances. I did work for a short time for National Lead back when they were still making lead-based Dutch Boy paints in a quality control lab. Lead oxide is made by literally burning lead. Lead ingots are stacked in a sort of fire-brick igloo and a heating oil flame is focused on the stack of ingots. They first melt to a silvery puddle and then start to form a yellow-gray powdery crust as air (oxygen) is blown through the liquid and it is stirred by a rotating paddle. It takes many hours as the lead combines with oxygen to form first PbO, PbO2 and eventually red-lead Pb3O4 which can be used in auto batteries as well as for rust protection paint. The guys who work in that factory would come into my lab and use my beakers for coffee cups even though I had just used them for lead tests, and it only took about one month in that environment before I developed black feces, the first sign of lead poisoning. Lead can be removed from your body with injections of EDTA which clings to the lead and releases it in urine but the EDTA injections feel very "hot" when you get them. In another clinical comment, a local plant in the Richmond area made a compound similar to DDT, namely Kepone, which is good for killing fire ants but again the main point is that factory workers making the stuff and walking around in 4" of it on the floor and in their lunch room developed severe persistant tremors. Unfortunately that led to a 20 year ban on fishing in the James river because the Kepone would collect in fish in the river and that basically wiped out the fishing industry on the tidal part of the James. It is believed that large quantities of Kepone are still buried in the river mud and whenever there is a storm the Kepone levels in the river rise. In both these cases it is a matter of amount. Too much is too much but for a while in the late 1940s DDT was used heavily for every application imaginable involving unwanted insects. Allowing that FOX news tends to be conservative and the Audobon Society more liberal it is not easy to sort out the truth but my answer would be to carefully control the amounts used and certainly maybe the West Nile virus may justify renewed use of DDT. In a humorous vein I note I used to have a '66 Ranchero which was pretty beat up but my fun idea was to have an eblem of the Kepone molecule painted on the doors with the motto "Kepone Trucking", but alas a tree fell on the roof of the Ranchero and my wife judged it to be beyond repair and we were luckyto sell it, but maybe someday I can put Kepone Trucking on a pickup truck

Much more dignified than the motto I had (briefly) on the driver's door of my 52 Pontiac in 64 -- "High Tone Son Of A B*tch."

Thanks for the thoughtful post, Don.

Two thoughts ---

**Everything** -- even water or oxygen -- is poison if taken in excess.

Birds should not work in industrial plants.

(Ok, I lied -- three thoughts) --

Believe no one who isn't provably neutral in all his views, even if his facts check out.

(Alright, I lied again. I don't really believe that last one and I'm pretty sure you don't either.)

Sorry about your Ranchero. I recently saw a 64 Cad somebody had chopped into a Ranchero wannabe. Shall I put in a bid for you?
