RE: Another RE: Relative Toxicity Pu Vs DDT
You have touched on something interesting. Yes. DDT ban is associated
with softening of egg shells and the consequent gross reduction in the
number of raptors. Peregrine falcons are the best known for their DDT
induced decline. Despite the oft repeated egg shell problem, it has not
been convincingly demonstrated. The experiment that is usually cited was
not reproducible by the investigator. As an amateur raptor biologist I
have pointed out this discrepancy to professional friends after they note
with dismay the very high level of DDT decay products found in successfully
nesting peregrines. My observation is rarely appreciated.

Subject: Another RE: Relative Toxicity Pu Vs DDT
When I was a student at San Jose State University I recall a professor
who periodically would eat DDT. As I recall the reason DDT was banned
was not high toxicity to humans but a problem with chronic ingestion for
endangered birds of prey. Softened the egg shells and led to more risk
of not hatching. Birds only produced one or two eggs a season and survival
rate to adulthood was not high anyway.
It would be interesting if both parties to the bet walked away from the
table. I beleive the Prof ate more than a gram. PLEASE UNDERSTAND I AM
NOT RECOMMENDING ANYONE TAKE THAT BET. I certainly would do some research
befor I would consider even consider it. But if the report is true, it
shows how we HPs can be prey to the same ignorance we decry in the uninform
ed public in fields outside of HP.
These are absolutely my opinions only and not those of my employer or any-
body else!
