Abstract

The amount of NO{sub 2} and NO produced by the machine smoking of cigarettes was determined for 15 commercial Canadian brands. Average yield of NO was 1.44 {mu}moles or about 13% of the average reported for American cigarettes. Levels of NO{sub 2} were all less than 12% of NO and were probably due to the oxidation of NO. In order to assess the contribution of tobacco smoke to levels of NO in ambient air, 5 brands of cigarettes were smoked in a 27 cubic meter controlled environment room. Ventilation conditions were either 2.5 or 5.0 air changes per hour (ACH) and each experiment was replicated 3 times for a total of 30 experiments. Ventilation rates of 0.3 and 1.5 ACH were also selected in a second series of experiments in which only one brand of cigarette was smoked. Least squares estimates for the effective ventilation rates were obtained in the usual manner after linearizing the decay portion of the NO time curve. In each of the experiments, the regression explained at least 95% of the variation in the levels of NO with time. Loss of NO due to factors other than ventilation appeared to be constant within experimental error andmore »« less

Maintain levels of nicotine but reduce other smoke constituents: a formula for ''less-hazardous'' cigarettes

Journal Article Robinson, J; Young, J; Rickert, W - Prev. Med.; (United States)

Twenty-two volunteers who smoked more than 20 cigarettes with ''high'' nicotine yields (0.8 to 1.2 mg) per day participated in an 8-week study designed to test the hypothesis that smoking cigarettes with a constant level of nicotine but reduced deliveries of tar, carbon monoxide, and hydrogen cyanide leads to a decrease in smoke absorption. All subjects smoked their usual high-nicotine brand for the first 3 weeks (P1), and the absorption of smoke constituents was determined from levels of thiocyanate and cotinine in saliva and serum, levels of carbon monoxide in expired air, and levels of carboxyhemoglobin in the blood.

Toxic volatile organic compounds in environmental tobacco smoke: Emission factors for modeling exposures of California populations

Technical Report Daisey, J; Mahanama, K; Hodgson, A

The primary objective of this study was to measure emission factors for selected toxic air contaminants in environmental tobacco smoke (ETS) using a room-sized environmental chamber. The emissions of 23 volatile organic compounds (VOCs), including, 1,3-butadiene, three aldehydes and two vapor-phase N-nitrosamines were determined for six commercial brands of cigarettes and reference cigarette 1R4F. The commercial brands were selected to represent 62.5% of the cigarettes smoked in California. For each brand, three cigarettes were machine smoked in the chamber. The experiments were conducted over four hours to investigate the effects of aging. Emission factors of the target compounds were alsomore »« less

Pharmacokinetics of nicotine in rats after multiple-cigarette smoke exposure

Journal Article Rotenberg, K; Adir, J - Toxicol. Appl. Pharmacol.; (United States)

The pharmacokinetics of nicotine and its major metabolites was evaluated in male rats after multiple-cigarette smoke exposure. A smoke-exposure apparatus was used to deliver cigarette smoke to the exposure chamber. The rats were exposed to smoke from a single cigarette every 8 hr for 14 days and to the smoke of a cigarette spiked with radiolabeled nicotine on the 15th day. Blood and urine samples were collected at timed intervals during the 10-min smoke-exposure period of the last cigarette and up to 48 hr thereafter. Nicotine, cotinine, and other polar metabolites were separated by thin-layer chromatography and quantified by liquidmore »« less

Yields of tar, nicotine, and carbon monoxide in the sidestream smoke from 15 brands of Canadian cigarettes

Journal Article Rickert, W; Robinson, J; Collishaw, N - Am. J. Public Health Nation's Health; (United States)

Sidestream smoke yields for 15 brands of cigarettes were determined under conditions where mainstream yields were approximately equal to those used for determining the values which appear on packages of Canadian cigarettes. Sidestream yields of tar, nicotine, and carbon monoxide were much higher than mainstream yields for all brands tested. The average sidestream-to-mainstream ratios for the 15 brands were 3.5, 6.6, and 6.8 for tar, nicotine, and carbon monoxide, respectively. The highest yields of sidestream were obtained from the brands with the lowest mainstream yields.

Reduction of the elastase inhibitory capacity of alpha 1-antitrypsin by peroxides in cigarette smoke: an analysis of brands and filters

Journal Article Cohen, A; James, H - Am. Rev. Respir. Dis.; (United States)

A procedure for measuring the oxidant content of aqueous condensates of tobacco cigarette smoke is described. The procedure was used in conjunction with analysis of the ability of the smoke solutions to inactivate the elastase inhibitory capacity (EIC) of alpha 1-antitrypsin. The ability of the smoke of a brand to inactivate alpha 1-antitrypsin correlates well with the known tar and nicotine and with the amount of oxidants as measured using o-dianisidine. Filters were found to remove about 73% of the oxidants from smoke. Smoke from a commercial nontobacco cigarette was also found to contain a significant amount of oxidants andmore »« less
