Dr. Shearer: That as in Portland, 'v~ forgotten the author of the
paper, but I know I have it in the f.les, I don't have that one with me.
But, it just indica'es that it's not imrtlediately broken down in theair~
that it can drift ad there can be a factor of interaction between the
herbicide and the b j eakdown product. . ,
Besides 2,4-di-chol1rophenol being r idly absorbed through the lungs,
2,4-D is also very1apidly absorbed t rough the lungs. It's been shown
so in a paper publi hed by Burton e al, Kansas City MiSsouri. It
shows a almost imme,iate absorbtion f 2,4-D through the lungs in rats.
This was a careful ,aboratoryexperi nt.And this was the 2,4--D acid,
and one should expeit that the ester would be absorbed more rapidly than
the acid because th yare much more l.pid soluable. Thei esters are
highly lipid solua,le, whereas the id is much less so,'and since animal
membranes are pri,r lipid membrane, lipid soluable compounds a gener~lly
absorbed through me,branes much fast than water soluable compounds, but
it showed - let's s,e if I've got th number here - The time necessary
for 50% absorbtion :f the 2,4-D was 1.4 minutes, which is pretty rapidl
You don't exhale muh at that rate. i
I want to go back t the matter of re roductiveeffects and the possibility
of synergistic effets at a very low level. It's also be~n demonstrated
by a study done by !he United State Council on Environmental Quality, a'
federal council, ju't a few years ag , that of all the teratogenic com-'
pounds, chemicals, jot just pesticides, ,known to be teratog~nic orcaus$
birth defects, in b' th human and ani ls, where there was.' data on human~
and animals, humansiwere the most se sitive species. In other words, ·
effected at the low st dost of any - in,all the cases. And they w~re etght
they had eight chem cals. There were also eight chemical$ that ca'4sed I
other reproductive'ffects other tha birth defects. And humans were t~e
most sensitive spec;es in seven case. 'So, when one is going to talk a9out,
especially about re'roductive effect, really a one hundredfold safety i
margin is not adequ~te. In the case of Thalidomide, for instance, a I
notorious teratogen' humans were sev hundred times as sensitive as i
hamsters. It tookne seven-hundretof the hamster dose caused human i
birth defects. Sone needs to be a ittle careful about that arbitrary
one hundredfold saf ty factor. '
It is true, as the, your other said, that 2,4-D is rapidly
excreted from human and animal bodies, however, this certainly does
not prevent a hit aid run effect. I other words, irreversible al~
terations that pers.st beyond the li ,beyond the time of the chemical
being in the body. jHit and run inju .es can include damage to nerves,
cancer, mutations, lancer initiation .TI,the first step is a hit and run
effect, mutations, .nd apparently so <;1.amage to the immune system is
caused after, by hi '-run chemicals t t'are long gone before the problem
manifests itself. eripheral neurop hy in fact, manifests itself'
generally after the chemical has bee excreted to the poihtwhere you
can't get positive ,lood and urine t ts. Inmost cases,. the tests wil
be negative, which's rather inconve ent in terms of being able to
prove the cause of :he peripheral ne opathy because by the time you're
sick enough to real' ze there is a ma r' problem it's too ~ate to do,'

Dr. Shearer (Continued): Now the av ilable cancer tests on 2,4-D, I
consist of only three world wide. 0 Ie was the Hanson paper, the ~D~

it doesn't meet current standards. rtshowed sign.ificant, increase' iln

trends toward. increase in tu.mors or ~ Ijlaligna,n. t tumors, t:. hey comP.a~ed
in both ways. It did not show a sig~ificant ipcrease at a particQl~r
dose in the femal~ rats. So it generally isn't accepted as proof ~~
carcinogenesis, although it is certai ly highly suggested that this I
histology, did histopathology on the tissues instead of just grossl
autopsies, and used more animals. It'sa good chance that one wo~l find
a statistically significant cancer i crease. '
One other study was done. by, under co tract with the national Cande
Institute back in the 60's, it was a e~tremely poor study. The matlerial

of the chemicals were tested orally, lincluding 2, 4--D, but at far t'o;
low a dose and far too short a time, and too few animals. So that' study
has been deemed by EPA Scientific Ad isory Panel to be useless rega dless
of the results , positive or negative. And in fact the oral test ~asl
negative and the subcutaneous test was positive. But, the advisory Ipanel
has said just don,' t show us that test any more, it's meaningless qeclause
of the poor quality. So, that rules ~out test number 2, t};1e third lo~e

repetitions to show that it is negati e' in the Ame test. The Amels
certainly doesn't rule out mutagenicity, it measur s onl one kindl

Dr: Shearer Continued: There was dis ussion about the h If-life i~ he
environment of 2,4-D with a favorite umber being about if teen days.
The half-life in forest soil in t e P Cif.iC Northwest ,tfat was fro..' m

here. But you should know that that est, when th y mea ure the half

They're simply saying we don't, alf. f the 2,4-D is not 2,4-D anymore.
They're not saying that it's gon. T.' ere are six r sev n step? in

not longer subjected to the sar(J.e sour esas in the soil. 'So only the
