Luzenac America Technical Center 8985 East Nichols Avenue Englewood, CO 80112 (303) 643-0451 Fax: (303) 799-8926 November 2, 1993 PLAINTIFFS EXHIBIT CAM-357 PHILIP MOREAU Toulouse RE: ACTINOLITE FOR TOXICOLOGY STUDY Project No. 93-077b Dear Philip, Finally, at long last, AEM analyses of the actinolite samples collected by Lance Meade have been performed. Scanning-transmission electron photomicrographs taken with our JEOL-1200EX AEM of an actinolite sample from the vicinity of Windham, Vermont, and one from the vicinity of Ludlow, Vermont, are presented on the attached plates. Plate I displays photos of actinolite from the Windham area. All grains examined were cleavage fragments; grains that would qualify distinctly as asbestiform-i.e. showed broom-tail terminations and curvilinear fiberswere not detected. Grain morphology ranged from low to very-high aspect ratios. Plate II shows photos of actinolite from the Ludlow area. Grains that would qualify distinctly as asbestiform were not detected. Morphologies included low and very-high aspect ratios. This sample seemed to have a lower average aspect ratio than the sample from the Windham area. Both samples will be sent to you in rock form. The rocks are not pure actinolite, but I hope that enough actinolite can be removed in order to suit the needs of the toxicology study. If you need additional samples, please contact either myself or Lance Meade. Best regards, Michael Clark copies to: Bill Sevy, J.P. Grange, files.
