Preface of the Conference In the four decades during which there has been acceptance of potential hazards associated with exposure to asbestos, solutions to the problems involved have been elusive, Therapyof asbestosis remains largely a rearguard holding action once the diffuse interstitial fibrosis is established. Prophylactic measures are hampered by difficulties In early diagnosis, including the long latent period often noted between onset of exposure and clinical change. Hard won data have been accumulating which indicate that neo plasia associated with asbestos exposure, especially those of the lung, are perhaps the most important industrial cancers at this time. This importance has been emphasized by the recent stimulating studies of South African and British investigators demonstrating the significant incidence of pleural and peritoneal tumors associated with asbestos exposure and by the knowledge that the various neo plasms might follow exposure of limited duration and intensity, in adequate to result in significant asbestosis. There have been effective advances in dust control techniques, accomplished by diligent, ingenious and expensive engineering. However, application of these procedures has been hampered by the rapid growth of asbestos utilization, sometimes under circum stances in which exposure has been obscure or unrecognized. More over, community and indirect occupational exposure may occur; the scope and importance of such "asbestos air pollution" are at pre sent uncertain but their potential significance has attracted atten tion. The foregoing sober inventory provided the stimulus and back ground for this Conference. The Scientific Council of the Academy considered that the interdisciplinary nature of the problem, involving such distinct fields as experimental pathology, applied physiology, oncology, epidemiology, and industrial hygiene could best be served by a broad conference of investigators in the biological sciences and those In allied fields. , In October 1963 visits were made by Dr. Selikoff on behalf of the Academy to several European centers to investigate the feasibility and potential scope of such a conference. In particular, British studies were reviewed with Dr. J.C. Gilson, Director of the Medical Research Council Pneumoconiosis Research Unit. The cooperation of Dt. 11. Heimann of the Division of Occupational Health of the United Stat.es Public Health Service facilitated a survey of current work tn this country.

The Academy was fortunate in securing the advice of a Con ference Committee which encompassed the major areas involved. Its members, themselves actively concerned with the problem, met January 6, 1964 in New York. The preliminary design of a meeting then formulated was refined during the succeeding months by thp Committee with the assistance of active investigators in many parts of (he world and by July, 1964 the Conference program was com pleted. It is thp hope of the Academy that this Conference will be u fertile one and will lead to decisive findings on this important problem.
