CORESTA Meeting, Smoke Science/Product Technology, 2011, Graz, ST 35 Cigarette smoke toxicant exposure estimates in smokers switched to reduced toxicant prototype cigarettes SHEPPERD C.(1); ELDRIDGE A.(1); McADAM K.G.(1); MARINER D.(1); PROCTOR C.(1); MEYER I.(2) (1) British American Tobacco, Group R&D, Southampton, UK; (2) Principal Investigator, Momentum Pharma Services, Hamburg, Germany We have conducted a study that addresses the first part of the IOM's definition of a potential reduced-exposure product by analyzing biomarkers of exposure (BoE) in smokers switched to prototype cigarettes which, when measured on smoking machines,...
Bull. Spec. CORESTA Congress, Brighton, 1998, p. 167, ST18 Determination of nicotine evaporation from mainstream smoke using denuder tubes MARINER D.C.; FROST B.E. Rothmans International Services Limited, R&D, Basildon, Essex, England. The rate of nicotine transfer to a smoker and the site of absorption within the human respiratory tract may depend on the distribution of nicotine between the vapour and particulate phases of mainstream smoke. A technique has been developed to...
Bull. Spec. CORESTA Congress, Brighton, 1998, p. 167, ST19 Factors related to nicotine physio-chemistry and retention in human smokers SINCLAIR N.M.; FROST B.E.; MARINER D.C. Rothmans International Services Limited, R&D, Basildon, Essex, England. It has been alleged that tobacco companies add ‘ammonia forming compounds’ to cigarette tobacco to "increase as well as control the delivery of the alkaloid nicotine to the respiratory tract of the smoker". It is claimed that such compounds make...
Bull. Spec. CORESTA Congress, Brighton, 1998, p. 191, ST45 Quantifying ETS exposure SEWART A.P. Rothmans International Services Limited, R&D, Basildon, Essex, England. Epidemiological studies into the alleged health effects of ETS typically use questionnaires which, at best, quantify ETS ‘exposure’. However, exposure is not, in itself, sufficient; what is required is a measure of the substance that enters the body...
CORESTA Meeting, Smoke/Technology, Hamburg, 1997, ST03 Benzo(a)pyrene analysis in mainstream cigarette smoke MARINER D.C.; TUCK D.J.; FROST B.E. Rothmans International Services Limited, R&D, Basildon, Essex, England. Benzo(a)pyrene, along with other polycyclic aromatic hydrocarbons, is formed during the incomplete combustion of organic matter and its presence in tobacco smoke is well documented. The low levels present in tobacco smoke and the complexity of the...
CORESTA Meeting, Agronomy/Phytopathology, Montreux,1997, AP66 Genetic modification of tobacco: public perception GREGG E.O. Rothmans International Services Limited, R&D, Basildon, Essex, England. Alteration in the characteristics of plants and crops has traditionally been achieved by breeding techniques; however, recent developments in molecular biology now allow the introduction of specific, desirable traits into plants by direct genetic...
CORESTA Meeting, Smoke/Technology, Hamburg, 1997, ST25 Packaging issues in Europe SINCLAIR N. Rothmans International Services Limited, R&D, Basildon, Essex, England. Traditionally, CORESTA activities have focused on the tobacco plant, processed tobacco plant, processed tobacco and the finished product rather than the packaging in which the product is sold. In Europe, environmental (green) factors, culminating in...
CORESTA Meeting, Smoke/Technology, Hamburg, 1997, ST26 Principles of public health risk assessment SEWART A. Rothmans International Services Limited, R&D, Basildon, Essex, England. Attempts by various regulatory authorities to perform risk assessments on substances such as Environmental Tobacco smoke (ETS) have been controversial and fraught with error. An understanding of Risk Assessment methodology is therefore useful. Public...
Tob. Sci., 1994, 38-23, p. 90-93, ISSN. 0082-4523 Delayed topping effects on the yield, value, and leaf chemical components of photoperiod-sensitive flue-cured tobacco STOCKS G.R.; WHITTY E.B. University of Florida, Gainesville, FL, USA; Rothmans International Services Limited, Denham, Uxbridge, Middlesex, UK The propensity of flue-cured tobacco (Nicotiana tabacum L.) cultivars to produce higher yields due to early topping is well documented. However, most studies on time of topping have not documented yield and chemical components by stalk position. This...
