Okay, busted. 
That stuff doesn't really fit the test of "modern".
That's what I get for overstating.

Perth has a heavily contaminated site as well as Derby in west au.The story

agriculture minister is calling for more information on the alleged heat 
damaged batch believed imported between 69-71 disguised as another 
chemical.Said to be 200 times worse than the now banned 245T.The EPA has 
been called 
in.http://www.theaustralian.news.com.au/common/story_page/0,5744,3553659%255E2702,00.html

I wouldn't cook polyhalogenated phenol dry or in high-boiling point

Dunno, maybe you're right, I couldn't get it to happen in the lab
with phenols when I was a chem student without actually burning it. I
tried. (wasn't supposed to but I was curious). Biphenols, yes. Or
something close enough to TCDD that I didn't care. Actually burning
245T, and 24D for that matter will indeed produce TCDD. As to whether
or not overcooking these phenols produces it, well, I wouldn't 
doubt it. But overcooking would still be a faulty process. 

BTW, burning just about ANYTHING with chlorine in it will produce
dioxin.

I don't know there brother nobody, I just keep reading over and over
again, folks using 245T, 24D and TCDD practically interchangably. 
They are not the same chemicals, not at all. I read things like
"245T, a form of dioxin" and "Agent Orange, a strong dioxin".
You say TCDD is a breakdown product of 245T, others say it is a
manufacturing byproduct, others say it is the same thing.

Well, most farmers in the world still don't have nearly the output that
the "chemically dependant brainwashed, braindead amerikan farmer" does,
except perhaps those other hi output ag industries from Germany, the
netherlands and such. All of which are of course, heavily chem dependent. 

Herbicides have existed a hell of a lot longer than 50 years, even
so-called modern chlorinated herbicides have been around since the 
late 1800s.

The reasons the "chemically dependant brainwashed, braindead amerikan 
farmer" is becomming exinct has a lot more to do with international 
corporate farming and economics of multinational monopolies like
Archer Daniels Midland, the darling of the NPR crowd, than it
does the use of herbicides, pesticides and fertilzers.   

Perhaps you are right on all cases, that agent orange
and all phenoxyl herbicides are the devils spawn and the 
true root of all evil. My imagination balks at it, perhaps because
I don't share your clarity of vision. However, I do know some
of the chemists at Dow Midland who were directly involved in
Dows work with 245T, and to follow your line of thinking is
to say that these folks are the fine agents of the great
satan himself, heirs to those nice folks who stirred the pot
so vigorously in europe back in the 40s.

My imagination balks at it, perhaps because these
folks simply are not like that, and I have read a lot of
the papers, I have done some of the chemistry and have learned
in an empirical way that these questions are all 
a great deal more complicated than these flat statements
like "Agent Orange is the blame for all the ''bad
things''" suggest. 

This is all real touchy stuff, I have been around
pretty much half a century and have been litterally
up to my neck in this stuff. (Yes, this *STUFF*). 
I don't take it lightly, and I don't buy into any
corporate line, as a corporation is almost by
definition incapable of telling any truth when there is
any bad news. But little snippits that say ag/chem
is evil, and we are good because we say it is evil
are pretty much a waste of everyones time.

An irony is a terrible thing to waste, whether one believes that dioxin is

to say, or not...

Agent Orange is a 1-124-1 mixture of n-butyl esters,
245T 2-4-5-trichlorophenoxacetic acid (C8,H5,Cl3,O3), and 24D
2-4-dichloro-phenoxacetic acid (C8,H6,Cl2,O3).

TCDD or, 2-3-7-8-tetrachlorodibenzo-P-dioxin (C12,H4,Cl4,O2), is a
CONTAMINATE artifact of the heat exchangers used in the reaction process 
not a constituent as so often stated. 

None of this stuff is what any of us want in our dinner salad, however
the differences between 245T,24D the most researched herbicides in the
world and TCDD are huge. 

Currently, aside from dioxin like pcbs (which are no longer
manufactured in the US, and wouldn't be around at all hardly
if it weren't for the americans and computer users love
of electricity and plastic lawn furniture) the only real use of dioxin is
in bleaching paper pulp. The understanding of dioxin is still incomplete
and with all the new studies in gene research on, folks are learning
some pretty interesting stuff about some theoretical benificial
capabilities of dioxin. In the short term, it's abilities to bind
up lipophilic chemicals so they can be pissed out as urine, and in the
long run, as a vector for non intrusive reprogramming of cells.

Chlorinated herbicides have been around since the late 1800s, and have
litterally made all the difference in the abilities to produce food
in the last century. While the ability to produce food in the 20th 
century has produced all kinds of new global problems, and food
is still used as a political tool, the problems of world wide
starvation are problems of politics, not agriculture. The techology
exists, and chemicals like 24D and 245T are among the reasons why.

Bad shit happened in the land of bad things to a lot of people. 
I've lost friends, close friends, to health proplems resulting from
exposure to agent orange, so I don't take this lightly. If the herbicide
had been manufactured with a priority on quality instead of the usual 
gov focus on low bid and quantity, it is at least conceivable
that this horror wouldn't be facing those folks now. 

As far as I know the only controlled studies done on agent orange were
done by the principle contractor Dow chemical, and the studies
were done in Midland Michigan. Those studies pointed heavily at 
TCDD contamination. As far as I know, those studies have not
been refuted. 

I am not a biochemist, and I don't even play one on TV, but I do
know how to read, and I wish that if folks wanted to report on this
stuff, they would get their facts straight.
