Identification, Emission and Abatement Methods of VOCs Derived from Cigarette Smoke

For a long time now, cigarette smoking has been recognized as a primary source of toxic chemical exposure for people. Among said toxic chemicals, VOCs are identified as being the highest contributing category to the overall toxicity of cigarette smoke. Thus, in this review an identification of the various VOCs present in cigarette smoke (mainstream, sidestream and environmental tobacco smoke) was first conducted, followed by a survey of the different factors affecting their emission level. Then, a study of the presently used techniques for the abatment of cigarette smoke-derived VOCs was performed. Finally, an assesment of some potentially interesting catalytic systems for the reduction of VOCs emission was carried out.
