%X <p>“Sub-ohm” atomizers with reduced resistance can deliver more power than conventional electronic cigarettes.<br />Typical battery outputs are 100 W or more. These devices are particularly popular among young users, and can<br />be a significant source of volatile carbonyls in the indoor environment. Emissions from next-generation sub-ohm<br />vaping products were characterized by determining e-liquid consumption and volatile aldehydes emissions for<br />several combinations of popular high-power configurations. Tests explored the effect of dilution air flow (air vent<br />opening), puffing volume, and coil assembly configuration.</p>
