Table 4 lists the 26 metal isotopes present in the mainstream smoke
produced with e-charcoal. Figure 4 depicts the six toxic metals in box
chart form and shows a marked decrease in toxic metals present in
the mainstream smoke during a 30 minute smoking session with
steam stones and e-charcoal. This finding confirms, perhaps the expected
result, that the toxic metals we detected are released from the charcoal
— a serious consideration for those who choose to smoke hookah in
a traditional fashion, which has been substantiated by earlier studies
[17,20,40].
To date this research indicates the metals do not consistently travel
through the apparatus to the filters during a simulated smoking session
and depend on the heat source and its physical characteristics at the time
of smoking, as well as performance of the filters. However, it is clear that
there are differences in metal amounts present in the smoke when using
traditional charcoal compared to e-charcoal.
