Analysis/Evaluation of Leaf
A shipment designated 16,027222Z-10 was received by the
Analytical Research Division, 23 February 1984, from FSTC.
The sample was also identified with the TH
number
840209-10DL. The shipment_gonsisted of a single leaf having
a 2 mm yellow spot and coniainerized in a plastic bag. No
further information was available about the sample.
A vapor sample withdrawn from within the plastic bag
containing the leaf was subjected to analysis by gas
chromatography/mass spectrometry (CC/MS). A portion of the
spnt was leached with chloroform. Another portion was
leached in 1:1 methanol:water. The solvent soluble
materials were analyzed by GC/MS, ion chromatography (IC),
thin layer chromatography (TLC), and Infrared spectrometry
(IR).
The GC/VS spectra of the vapors associated with the
loaf identified the presence of dimethyl phenyl indine. The
chloroform sclubles did not give a definitive GC/MS spectra.
IC was neg3tive for all ions of interest. TLC separated a
UV flourescent compound, Rf=.75, and a red colored
component, Rf=.80. These separations are similar to those
given by reference vegetation samples. Derivatization with
negative icn chemical ionization MS detection for
trichothcenes was negative. IR spectra identified the
presence of aliphatic hydrocarbons and traces of
indefinitive components.
Conclusions
No evidence of any known CW agents, agent degradation
products, cr trichothecenes was detected. The sample
appears to be innocuous.

Analysis/Evaluation of Vegetation and Stone Samples
A shipment designated 100271(4) was received by the Analytical
Research Division, 28 February, 4984, from FSTC. The analysis of five
samples, 100271(4)-1 (TH840209-100, 100271(4)-4 (TH840209-401), 100271(4)-5
(TH840209-500, 100271(4)-6 (1H840209-600 and 100271(4)-7 (TH840209-7DL),
have been previously reported. Additional analysis have been completed on
three samples. These include a small stone with one yellow spot two mm in
diameter containerized in a plastic bag identified with TH840209-301. and
designated 100271(4)-3, two leaves with white and rust spots from one to
nine mm in diameter. containerized in a plastic bag identified with TH840209-901_
and designated 100271(4)-9 (Figure 1) and one leaf with one yellow spot
containerized in a plastic bag identified with TH840208-1LP and designated
100271(4)-12 (Figure 1). No further information was available on these samples.
A separate vapor sample withdrawn from within each plastic bag was sub-
jected to analysis by gas chromatography/mass spectrometry (GC/MS). A portion
of each sample was extracted with chloroform. Another portion of each was
extracted with 1:1 methanol:water. The solvent soluble materials were analyzed
by GC/MS, ion aromatography (IC), thin layer chromatography (TLC) and infrared
spectrometry (IR).
100271(4)-3 (TH640209-301) stone
The GC/MS spectra of the vapor associated with the stone identified the
presence of Otrimethyl phenylindene. The GC/MS analysis of the chloroform
solubles gave no definitive spectra. IC separated no ions of interest. No
detectable components were separated by TLC. Derivatization with negative ion
chemical ionization 115 detection was negative for trichothecenes. IR spectra-
identified a trace of aliphatic hydrocarbon and a silicate possibly soil.
100271(4)-9 (TH840209-901) two leaves
The GC/M5 spectra of the vapor associated with the leaves identified
ithe presence of 2.3 dihydro, 1.1,3-trimethy1-3-phenyl-11-1 indene
Chloroform solubles from each of the leaves gave no definitive GC/MS spectra.
IC detected no ions of interest from either leaf. TLC detected two
components from the small leave with yellow spots, a UV fluorescent component,
RF 0.77-0.83, and another reacting with the p-anisaldehyde reagent to give a red
spot at Rf 0.83-0.88. Only one component was detected from the large leaf
with rust spots, a UV fluorescent material. Rf 0.73-0.79. Derivatization
with negative ion chemical ionization MS detection was negative for trichothecenes
in both leaves. IR spectra related to the small leaf identified the presence
of aliphatic hydrocarbons and a band at 1610 cm-1, tentatively identified as

a carboxylic acid salt. IR spectra related to the large leaf identified the
presence of aliphatic hydrocarbons and a carbonyl band at 1720 cm-1.
100277(4)-12 (TH840208-1LP) one leaf
The GC/MS spectra of the vapor associated with the leaf identified the
presence of a compound similar to hydroxytoluene, having a di-t-butyl
group with one unsaturation. The GC/MS spectra of the chloroform solubles
identified the presence of phthalates and six high boiling aliphatic hydro-
carbons, bp 250" - 290', > C36. IC Kis negative for all ions of interest. TLC
separated one component, which yielded apurple spot Rf 0.1-0.15 on reaction
with p-anisaldehyde. Derivatization with negative ion chemical ionizatIon M5
detection for trichothecenes was negative. IR spectra identified the presence
of aliphatic hydrocarbons, carbonyl and CO.
Conclusions
No evidence of any known CW agents, agent degradation products or
trichothecenes was detected. The significance of the detection of trimethyl-
phenyl indene in two of the samples is not evident at this time. The
samples appear to be innocuous.

the leaves was leached in chloroform. Another portion of the leaves
was leached in 1:1 methanol:water. The solventsolublematerials were
analyzed by GC/MS, ion chromatography (IC), thin layer chromatography (TLC)
and infrared spectrometry (IR).
The GC/MS spectra of the vapors associated with the leaves identified
the presence of a series of fatty acids including hexanoic, heptanoic and
isooctyl acids, and an unidentified compound of molecular weight 208
having a base peak 123. The 6C/MS spectra of the chloroform solubles
showed only a possible trace of chloro compounds. IC separated no ions
of interest. No detectable components were separated by TLC. Derivatization
with negative ion chemical ionization MS detection for trichothecenes was
negative. IR spectra identified the presence of water and aliphatic
hydrocarbons.
Conclusion:
No evidence of any known CW agents, agent degradation products or
trichothecenes was detected. The detection of volatilized fatty acids in
this sample, 100271(4)-5 and 10027Z(4)-6, but not in the reference vegetation
would indicate they are not naturally occurring vegetation components. They
are components of the MA thickener for napalm, but the aluminum salts used
in the 14r4 Wert not detected.

The MS spectra was identical to that of 1002744)-6, indicating a large quantity
of an unidentified compound which underwent derivatization. The IR

Conclusion:
No evidence of any known CW agent, agent degradation product or trichothecene
was detected. Submitted as a reference sample, the components separated by
thin layer chroratogra'hy and the component which underwent derivatization
afford excellent base iine data for evaluation of suspect samples.
