ENVIRONMENTAL TOBACCO-SMOKE (ETS) - A MARKET CIGARETTE STUDY

The environmental tobacco smoke (ETS) yield of selected analytes was d etermined for the 50 top-selling U.S. cigarette brand styles (1991) an d the University of Kentucky Research cigarette, K1R4F. ETS was genera ted by smokers in an environmental test chamber. Analytes determined i ncluded real-time measurements of nicotine, 3-ethenylpyridine, respira ble suspended particles (RSP), carbon monoxide, and total hydrocarbons by flame ionization detector response (FID). Real-time RSP values wer e determined independently by a piezoelectric balance and real-time ae rosol monitor (RAM). Additional analytes determined on a time-integrat ed basis included: nicotine, 3-ethenylpyridine, myosmine, RSP, ultravi olet particulate matter (UVPM), fluorescent particulate matter (FPM), solanesol, scopoletin, formaldehyde, acetaldehyde, acetone, catechol, ammonia, 34 volatile organic compounds (VOCs), and total VOCs (estimat ed by GC/mass spectrometric response). In general, lowering mainstream tar resulted in lower ETS emissions. The current study showed that ET S-RSP and nicotine were not predictive of each other. In fact, this ET S market brand style comparison showed a poor relationship between ETS nicotine and ETS-RSP. ETS analyte yields are summarized by mainstream tar categories, and overall sales-weighted average yields are calcula ted. Sales-weighted average ETS-RSP yields for full flavor (FF), full flavor low tar (FFLT), and ultra low tar (ULT) were 14.86, 12.30, and 10.51 mg/cig, respectively. The average RSP yield for all cigarettes e valuated was 13.67 mg/cig. These results, based on 65.3% of the U.S. c igarette market, should enable better estimations of the contribution of ETS to indoor air. Copyright (C) 1997 Elsevier Science Ltd.
