Cigarette smoke is a complex non-equilibrated mixture of chemicals (predominantly air) with thousands of compounds being generated from the incomplete combustion of tobacco. These are distributed between the gas phase and the particles (the...

Numerous papers have been presented at previous conferences examining the characteristics of filter cigarettes containing activated carbons on the removal of vapour phase compounds from smoke. All these studies have been carried out on triple...

A real-time sampling system has been set up to monitor a group of volatile smoke analytes (nitric oxide, acetaldehyde, acetone, benzene, toluene, 1,3 butadiene, isoprene and carbon dioxide) in mainstream cigarette smoke on a puff-resolved basis. The...

In 2001, the US Institute of Medicine coined the term "Potential Reduced-Exposure Product", referring to novel tobacco products which yield reduced tobacco smoke constituents with a reasonable expectation to lower consumer health risks. Although...

Historically studies on the deposition of tobacco smoke particulate matter have been based on measurements of inhaled and exhaled solanesol, an involatile long-chain alcohol specific to tobacco. This study examined the utility of determining...

A study was conducted to determine the regional deposition of tobacco smoke aerosol in the respiratory system of smokers, using real-time measurement of respiration and inhaled and exhaled smoke.Six current smokers were recruited, giving informed...

For the risk assessment of cigarette smoke, it is desirable to have a reliable estimate of the mass of chemical compounds retained in the body during smoking. Filter studies can provide reliable estimates of mouth exposure to compounds in cigarette...

The long-term health effects of cigarette smoking have been extensively investigated and are well known. Many studies have reported the effects of short-term switching on smoking behaviour. However, few long-term studies have been conducted recently...

Tobacco specific nitrosamines (TSNA) in cigarette smoke are an important class of toxicants. Therefore the quantification of TSNA via spent filters from smokers is a valuable addition to the filter analysis method. Previous research has shown that...

A framework of laboratory, clinical and consumer evaluations is being developed that will allow a scientific assessment of whether use of new technologies and tobacco products is likely to result in (1) substantial reductions in exposure to tobacco...
