It is important to analyze tobacco smoke and gas components. To control gas and smoke released from cigarettes, we need to study the three processes involved in generating tobacco smoke. This includes the tobacco smoke components releasing...

Vapor pressures of thermal decomposition products of tobacco are an important parameter in understanding pyrolysis behavior of the tobacco. The extent to which the tars can vaporize, before retrograde reactions reincorporate them into a char, plays...

It is well known that nitrogen oxides are toxic and that they are precursors for formation of nitrosoamines which are cancerous compounds. Catalytic decomposition of nitrogen oxides to nitrogen and oxide is simple but very efficient procedure of...

In recent years there has been a growing interest in a much wider range of chemicals found in cigarette smoke, including constituents of both the vapour and particulate phases. This has been brought about by the requirement in British Colombia to...

Ammonia is generated in mainstream smoke (MS) from multiple precursors in tobacco such as amino acids, proteins, amino acid/sugar reactions and ammonia salts. Ammonia derived from both the particulate and vapor phases is measured with the...

Phenol compounds, which belong to significant components of tobacco smoke condensate, influence the quality of the cigarette smoking properties, although some of them have extremely distinct toxic properties. Some domestic blend type cigarettes with...

A puff -by-puff mainstream-smoke procedure has been developed that provides the sensitivity and selectivity of a Gas Chromatograph/Mass Spectrometer system. The smoke analysis is based on automated sample collection and injection into the gas...

The 1999 Massachusetts Benchmark Study, the first study of its kind in the U.S., has been successfully completed. Results of this study, together with earlies studies that employed other smoking regimens, confirm that "benchmarking" is a practical...

In addition to measuring tobacco smoke analytes, there will be an increasing demand in the future to establish guidelines for testing the biological activity of tobacco smoke. Thus, testing methods have been identified which can provide valid data in...

US and UK government agencies and academic researchers have proposed platelet aggregation in nonsmokers exposed to environmental tobacco smoke (ETS) as an explanation of the highly nonlinear dose-response relationship between ETS exposure and...
