Implications of Nicotine Sorption on Indoor Surfaces on its Use as a Marker for Environmental Tobacco Smoke

摘要

Nicotine has been widely used as a marker for environmental tobacco smoke (ETS) because its only significant source in indoor air is tobacco product combustion, it is easily detected, and different types of cigarettes emit it at similar rates. A strong correlation between nicotine concentrations and those of respirable suspended particles and other ETS consituents has been reported in real indoor environments where smoking occurs. However, other researchers have questioned the suitability of nicotine as a marker for ETS because of observations of differences between its dynamic behavior and that of other ETS constituents in laboratory chambers.
