BIOSIS COPYRIGHT: BIOL ABS. In order to understand the behaviour of tobacco additives in the burning cigarette it is important to know whether they transfer intact to the smoke or whether there is any decomposition during smoking. There are practical problems in comparing the chemical analysis of whole smoke from cigarettes with and without additives. Changes to the smoke chemistry may be insignificant in analytical terms and therefore missed from a general scan. Targeted analysis of key components potentially overcomes th igarette smoke chemistry. The variables that affect the outcome of combustion are temperature, rate of change of temperature, oxygen concentration and chemical environment (matrix and gas phase). The key to this work has been in performing pyrolysis experiments under a range of different conditions and relating the experimental conditions to those within the burning zone of the cigarette to give a prediction of smoke chemistry. To test the theory in practise, the transfer and the
