Moore, Jr., being duly sworn, deposes anc^ says: 1. I am currently employed as an epidemiologist by the National Institute for Occupational Safety and Health (NIOSH) , at 5600 Fishers Lane, Rockville, Maryland. My biography is attached to this affidavit as exhibit 1. 2. As part of my duties at NIOSH I was involved in the preparation of a "Dear Colleague" letter" which was sent out on August 20, 1976, by Dr. John F. Finklea, Director of NIOSH. A copy of that letter is attached to this affidavit as exhibit 2. 3. In this letter NIOSH reviewed the preliminary results of an epidemiologic analysis based on medical records of Mobil Oil Company employees exposed to PCBs at Mobil's Paulsboro, New Jersey plant. 4. Among the 92 workers studied, for whom adequate medical records were available, eight cancers (in seven workers) were 0267702 PCB-ARCH0744075 observed between 1957 and 1975. Of these eight cancers, three were malignant melanomas and two were cancers of the pancreas. This is significantly more skin cancer (melanoma) and pancreatic cancer than would be expected in a population of this size (based on the Third National Cancer Survey) . 5. Based on these findings and those reported earlier on the carcinogenicity of PCBs in test animals, it is my conclu sion that when the results of further studies on occupationallyexposed individuals are completed, there is strong likelihood that PCBs will be shown to be carcinogenic to humans. 6. NIOSH is currently conducting such follow-up studies on workers occupationally exposed to PCBs. Roscoe M. Moore 77 Sworn to and subscribed before me November, 1976.
