The environmental tobacco smoke (ETS) generated by cigarettes from nine countries was examined to determine selected component yields and ETS marker ratios. The countries tested included: Argentina, Australia, Brazil, Canada, China, England, Japan, Korea, and the United States. Six leading brand styles from each country were smoked in an environmental test chamber. Concentrations of the gas phase ETS components CO, NO, NO 2 , nicotine, 3-ethenylpyridine, myosmine, and total volatile organic compounds (TVOC) were measured. Particle mass concentrations were also measured along with the particulate phase markers ultraviolet particulate matter (UVPM), fluorescent particulate matter (FPM), and solanesol. The variation in the ETS generated by cigarettes from these nine countries was greater than observed in a previous test. Ratios of gravimetrically determined respirable suspended particles (RSP) to the surrogate standard concentrations for UVPM and FPM averaged 7.2 and 42, respectively. The average ratio of RSP to solanesol was determined to be 38. ETS component yields were relatively consistent among the countries tested and averaged 14, 59, 41, 1.3, and 0.4 mg/cig. for RSP, CO, TVOC, NO, and NO 2 , respectively. |
