Paoageorge Considerable interest has been contirjfces to be expressed by many involved in studies of FC3$ y d the 4hvironment concerning their degradability. Monsanto HSS rec^vsp. many inquiries relating to results of our studies. We now! have acoumulated some meaningful data which we believe would be appropriate to present in a status report to the Interdepartmental PC3 Task Force. We sincerely appreciate this opportunity to share this information with you this afternoon. Slide #1 - We plan to discuss current results of laboratory blodegration studies of FC3s and the levels of PCS residues observed in the tissues of laboratory animals which were used in our toxicity studies, V/e will review briefly actions Monsanto has taken to reduce FCB usage and environmental losses. We will also discuss the application of our laboratory findings to the development of a modified more readily degradable PCB mixture for use by' the capacitor industry as a dielectric fluid. As many of you are aware, we have designated this material as Aroclor 1016. Slide ?9 - Our presentation will begin with Dr. Tucker discussing primary bacterial degradation and FCB residues in fish, fowl and mammal tissues. Dr. Munch will review evidence that demonstrates disappearance of FCBs from the environment and Dr. Faton will discuss Monsanto's FCB sales and use actions and the impact these actions will have on the environment. Because of the limited time available, may I suggest that questions be held until all the speakers have completed their reports. Following the presentations there will be opportunity for further discussion of information which may be of particular interest to you. Dr. Tucker, Research Group Leader, will now present a status report of his laboratory results.
