CAAA90.
emission rate of a cigarette depends on the type of
tobacco, the density of its packing, the type of wrapping
paper, and the puffing rate of the smoker (Hines et al.,
1993).
Table 9.2 indicates that emission rates of sidestream
smoke are greater than are those of mainstream smoke

Table 9.2 shows main- and sidestream emissions for
some components emitted from cigarettes. The actual
