Elements including metals in the atomizer and aerosol of disposable electronic cigarettes and electronic hookahs
The concentrations of elements in the aerosol of NJOY King were measured at low (A) and high (B) air-flow rates, and are shown for each element in the pie charts as the percentage of the total concentration of all elements. Sodium was not measured in the aerosol from NJOY King puffed at a low air-flow rate. The total concentration of all elements is given at the bottom of each pie chart. Numbers adjacent to each element are concentrations in μg/10 puffs for that element. All concentrations are the average of three aerosol samples from three different ECs, and only elements that were higher than or equal to 0.002 μg/10 puffs are presented in this figure.
