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.
