Presentations at the Conference on Methyl Chloroform and Other Halocarbon Pollutants are documented. Included among the authors are research scientists, industry representatives, and regulatory officials. The 16 papers fall into 2 basic groups. The first 10 papers present results of research in atmospheric chemistry as related to the question of stratospheric ozone depletion by halocarbons. Drawing upon atmospheric measurements and model calculations, the authors give estimates of emission levels, current atmospheric burdens, tropospheric lifetimes, the importance of sinks, effects on stratospheric ozone, and related questions. The final 6 papers take the perspective of involvement in, or concern with, regulatory decisionmaking. The authors consider various options, recommendations, and plans for halocarbon control in light of available scientific data. Finally, the Panel Discussion which concluded the Conference is presented in verbatim transcript form. Focusing on the current status of atmospheric measurements, the participants discuss problems in obtaining accurate halocarbon data, and discrepancies between and within the results of individual investigators.
