cc: Dr. Richard Osland May 10, 1972 Dr. J. Clarence Davies, III Senior Staf f Member Council for environmental Quality 722 Jackson Place, W. W. trashing ton, D. C. 20006 Dear Dr. Davies: During the last two months our medical staff completed examinations on 27 hourly and salaried workers who were engaged in the manufac ture of polychlorinated biphenyl in our Sauget, Illinois Plant. These 27 workers had various lengths of service in the department. The shortest was six months and the longest was 12 years. The average time in the department was slightly over five years. Of these 27 individuals 16 had no detectable PCB's in the blood (using a method sensitive to 0.1 ppm) five had 0.1 ppm, two had 0.2 ppm, two had 0.3 ppm, one had 0.4 ppm, and one had 0.5 ppm. Clinical examinations were entirely negative. Laboratory examinations including blood counts and hematocrit, and clinical chemistries in cluding glucose, urea nitrogen, creatinine, uric acid, calcium phosphorus, SGOT, SGPT, LDK, alkaline phosphatase, bilirubin, cholesterol and total protein, showed no pattern of illness. There were some random high cholesterols, one high hemoglobin and one low hemoglobin. In only one case was the SGOT and SGPT elevated but this individual showed no detectable PC3 in his blood. In summary, I can say that these workers were as healthy as any cross section of our plant workers of the same age. P.EX/ln R. Emmet Kelly, M. D Medical Director OS*'**68 STLCOPCB4063597
