Stark General Offices An analytical procedure for extracting, concentrating, and measuring Aroclor at the sub ppm level in v/ator has been developed and verified with Aroclor "spiked" tap water samples (Table I). This procedure was employed to determine the tap water solu bility of Aroclor 1242, 1240 and 1254 (Table II). The Aroclor saturated tap water samples used in this study were prepared in the following manner: two 60-70 g. portions of each Aroclor fluid were placed in 32os. narrow neck screw top glass bottles and 500 ml. of tap water (South Second Street) added to each. The bottles were then placed on a roller mill, rolled for 24 hours and allowed to stand undisturbed at room temperature (25C) until analyzed. The period of time between preparation and analysis was approximately 4-5 months. Inspection of EC/GC traces and the data in Table II indicates that the solubility or Aroclor is a funutiv:i oi A/Oth the amount of chlorination and the position. This anticipated behavior makes absolute quantification difficult since a standard with the same isomer distribution of the water solubilized material . is impossible to prepare. Therefore, the "Aroclor found" was calculated in this manner: the original Aroclor in question was used as a standard and a calibration curve prepared by plotting the peak height of the major isomers versus jug Aroclor. The peak height response .of the samples were then totaled, corrected for a tap water blank response and the amount of "Aroclor found" determined from the calibration curve. A rough idea of the error inherent in this procedure can be obtained hy using 1242 as a standard for 1248, etc. A devia tion on the `order of +10% was experienced. The data in Table II also seems to indicate that a stable Aroclor-water emulsion is formed at approximately twice their solubility levels. The Pydraul fluids being multi-component systems are a completely different, story and as such will require much more effort. At this point, I think we should probably clarify what information is actually desired and if the need for this information can be justified in terms of the effort necessary to obtain it. db Attachments - 2 E.

His approach is not an absolute identification procedure. It's based on similar retention times for 10 com ponents eluted through a gas chromatography column. This measure ment is not specific for chemical compounds in unknown mixtures. Furthermore, the electron capture detector used to monitor sep arated component 1b not specific for chlorine or even halogens. Work in our labs shows at least 13 components in Aroclor 1242, 17 in Aroclor 1254 and l4 in Aroclor 1260 with different retention times than those reported by Risebrough. More information is needed about un-reported experimental chromatographic, conditions used by Risebrough to resolve differences between labs. Risebrough. has based his conclusions implicating chlorinated biphenyls on work by Holmes (3), Holden (3a) Widmark (4), and Jensen (5), Holmes and Holt obtained similar gas chromatograjfrvA' containing 11>13 and 7 peaks respectively for commercial polychlobiphenyl resin. Holmes and Holden also did not make a positive structure identification, Widmark and Jensen in Europe (Sweden) obtained a similar gas c h r o matograph for eagle extracts. Chromatographic fractions from this work were identified structurally by Mass Spec as higher . chlorinated biphenyls, Risebrough, in his reported work has apparently made no positive identification of this type. His 3 implication of chlorinated biphenyls appears to be by reference back to above 'work through similar chromatograms. To the best of our knowledge, no one has identified components structurally in biological systems as chlorinated biphenyls in^U.g.A. Work is underway in our labs on an unequivocal-structure identification of unknown organic species in n&ticnavyproducts using gac chro matography and mass spectroscopy techniques.

Richard - GO It has been proposed from the observed distribution of poly chlorinated biphenyls in tissue samples taken from marine organisms that global eco-distribution of these materials occurs via aerial transport (wind currents, airborne particulate matter, etc.). A qualitative experiment has been performed with the objective of determining if Aroclor in N.C.R. paper is destroyed or volatilized when the paper is disposed of by burning. The experiment was'carried out in the following manner. Approximately 3g, (1 sheet) of paper (CB 15s white, 8-1/2 X 11, long grain, F-3463-4-24-64, The N.C.R* Company) was placed in the incinerator chamber of the apparatus shown in Figure I. FIGURE I At this point the vacuum was turned on and the paper ignited. After the paper had completely burned, the hexane in each trap, and hexane extracts of the ash and the vralls ofthe incinerator chamber were analyzed for the presence of Aroclor by EC/GC. Hexane samples from trap 51 were also analyzed after extraction with base and acid to remove any oxidized materials. NEV 031200 W. K. Richard March 4, 1SG9 Page 2 Conclusions: Under the conditions of this experiment: 0 1. Aroclor is easily volatilized when N.C.R. paper is burned. .2. Aroclor undergoes little, if any, decomposition when burned. 3. Unfortunately, it appears that significant air pollution can occur via burning of N.C.R. paper o r 'other Aroclor containing materials even under more strenuous conditions. JJ. s .

Waychofr/W. K, Schalie/ -- .7 J. E. Sprinta E.-Whecler/Dr. R. l. Kelly. I am sure the attached article in the Wall Street Journal of Karen J; on the DDT "trial'' In Wisconsin has not escaped your notice. It emphasises several things. 1. Dr. Risebrough seems to figure prominently in the proceedings. It could bode ill for Aroclors if the quotation attributed to him is true. "No responsible person could now get up here and say that this constant nibbling away at our steroids is without any physiological effect. It would be irresponsible," Not only does he appear to be setting the stage that anyone disagreeing with him is irresponsible, he seems to be equating any effect with a bad effect. This attitude has un~ p lC C iC u T rir u p A A V il 2. The fact that the DDT "task force" (Diamond/Allied/ Olln/Lcbanon/Montrose/Geigy)"did not retain an attorney to represent it at the hearings until less than a week before they opened, and apparent ly had almost no idea of what it would face" is a sobering thought. Have v/e taken steps to obtain the transcript of the proceedings as discussed at our meeting in January. Should we alert our legal people to the possibility of Aroclor "hearings" in the future so that we are fully prepared. 3 I note that several of the witnesses for the pro secution have also been asking for Aroclor samples. In the worst light, this could mean future trouble for us. I NEV 0 3 1 2 1 2 780750
