From: Compartmental analysis of metals in waterpipe smoking technique
Sketch illustrates the ‘Shisha’ set-up including the ‘head’ for containing the tobacco, the plastic hose for drawing smoke contains the filter and the water vessel through which the smoke is bubbled. The metal concentration distribution through the compartments of a waterpipe is also included. The values are averages of all metals (Bi, Cr, Cu, Fe, Mg, Mn, Mo, Ni, Pb, V, and U) and for four commercially available waterpipe tobacco samples. Sketch commissioned by authors [16].
