ETS Sub-Group Dr. Charles R. Green ILL Reynolds Tobacco Company P. O. Box 1487 Winston-Salem, NC 27102-1487 Telephone: (910) 741-4979 Facsimile: (910) 741-0719 AQ10441 ~S FROM CORESTA'S ETS SUB-GROUP MEETING Vienna, Austria September 15, 1995 Attendees: J. Jacques Piad~, J. Hollweg, M. E. Rocha, J. Sarabia, J. Bell, I-I. Re~ I-I. Bohanon, M. Intorp, L. Mfdler, B. Frost, T. Sanders, Y. Saint-Jalm, T. Sakaki, T. Nagata, T. Birkel, S. Purlds, C. I-fill, M.S. Rhee, M. Ogden, A. Dahlgren, and C. Green. The ETS Sub-Group held a half-day meeting on September 15, 1995 in Vienna, Austria at the Tobacco Land offices of Austria Tabak. The meeting was kindly hosted by Dr. Hubert Klus. Twenty-one members from 14 different companies were present. SUB-GROUP BUSINESS Dr. Michael Ogden informed those present that CORESTA's Scientific Commission had approved the designation change of this group from a task force to a sub-group. Additionally, Dr. Ogden confirmed that his nomination to be the new coordinator of the sub-group was also approved. He told the members that Dr. Charles Green, the former coordinator, had volunteered to be secretary to the group. There was no opposition to this proposal. Dr. Ogden reviewed the plans for the collaborative studio to further qualify several environmental tobacco smoke analytical chemistry methodologies. These include methods for nicotine, 3-ethenylpyridine, gravimetric RSP, UVPM, FPM, and solanesol. Copies of the most recent analytical method protocol for the particulate measurements were circulated to members present. This protocol was written by Dr. Ogden and his colleagues for ASTM. Any members, not present at the Vienna sub- group meeting and desiring a copy, should contact Dr. Ogden. Dr. Ogden presented a summary table indicating laboratories that have agreed to participate in the collaborative study and specifically, what analysis they were prepared to run. A copy of this table is attached. In total, 15 laboratories will participate in the test. Next steps (with proposed target dates) are the following: Collaborative study committee (M. Ogden, B. Frost, J.-J. Piad6) will finalize methods to be tested and the study protocol and distribute to participants (December, 1995); practice analysis will continue until all labs verifi/ successful implementation of the methods and any

methodological issues that may arise are settled; samples for the collaborative study will be generated and distributed (March, 1996); samples will be analyzed and results transmitted to M. Ogden (April, 1996); preliminary study results will be presented at the next sub-group meeting (May, 1996). The second major item of subgroup business was the proposal to conduct a world- wide survey of indoor air quality in restaurants. The purpose of this work is the following: Evaluations of indoor airquality are planned for restaurants where smoldng is permitted These evaluations are being done in order to provide scientific and technical information on the relationships among four variables: ventilation and filtration ~ystema; occupant perception, smoldng rates, and concentrations of indicators of indoor air quality and environmental tobacco smoke. Mr. Hoy Bohanon distributed a dratt protocol prepared by himsdt~ Nigel Warren, Helmut Rei£ and Masao Matsukura for conducting these restaurant studies. The dralt protocol contains a section with a questionnaire for measuring occupant perceptio~ All members were invited to comment on the questionnaire and to provide samples of any questionnaires that they have used in the past. The next steps will be: Finalize questionnaire: November 1995 lrmalize protocol and list of paaidpants: December 1995 Preliminary schedule for test activity: January 1996 Actual testing: February - April 1996 Compile preliminary results for discussion at task force meeting: May 1996 Data analysis: 'July 1996 Final report: September 1996 Presentation of final report to CORESTA: November 1996,. Discussions were held concerning the time and place of the next full meeting of the sub-group. Dr. Ogden recommended that a meeting be held in the spring .of 1996 possa"oly in Milan, Italy. He is taking responsibility for arrangements and will notify sub-group members in due comm. Since the meeting was scheduled for only one-half day, there was no technical program planned.
